= Launch Control =
Two-step / launch control: holds a fixed RPM off the line by cutting fuel and/or retarding and cutting ignition, so the driver can hold the throttle flat and launch on release. Activation can be by clutch, button, speed and/or throttle, and a separate rolling-launch mode is provided for roll racing.


== Launch Control Settings ==
All launch activation and effect settings: how launch is armed and triggered (clutch, button, speed, TPS, or rolling-launch), the launch RPM and cut window, and what happens at the limit — ignition retard, ignition and/or fuel cut, and fuel trim.

= Anti-Lag ALS =
Anti-lag (ALS): keeps a turbo spooled off-throttle by retarding timing, adding fuel and holding the throttle/idle air open so combustion continues in the exhaust. Strongly stresses the turbo and exhaust — the MAP/TPS/RPM/CLT/EGT limits here end ALS on timeout or instantly to protect the hardware.

= Traction Control and Vehicle Speed =
Vehicle speed, gear detection and traction control. Configure the speed source (local sensor or CAN) and individual wheel-speed inputs, then traction control compares driven vs driven-wheel speed and reduces torque on slip — via ETB closing, ignition retard, and/or spark skip.


== Vehicle speed sensor ==
Where vehicle speed comes from and how it is scaled — a local speed sensor or the CAN bus — plus gear detection derived from speed and RPM.

= Boost Control =
Turbo/supercharger boost control. Drives a wastegate or boost-control solenoid in open loop (base duty table) and/or closed loop (PID toward a target table), with overboost cut protection. Open- and closed-loop values can be trimmed by gear, CLT and IAT, and a table-switch input allows a second set of tables (e.g. low/high boost).


== Boost control options ==
Master boost settings: enable and control mode (open and/or closed loop), the wastegate/solenoid output(s) and PWM frequency, overboost-cut protection (including the feather and table-switch variants), and the RPM/TPS/MAP thresholds below which boost control is disabled.

= Generic PWM =
Up to four general-purpose PWM channels (GP PWM x, x = 1–4).

An optional switch pin selects or blends the table, 'off value' applies while that switch is off, and 'duty if error' is the safe fallback used if an input sensor faults.

All four channels are identical; only their index differs.

= User tables =

Per-table fields, identical for every table:
* '''Enabled''' / '''Enable Pin''' - turn the table on, optionally gated by a switch input.
* '''X Axis''' / '''Y Axis''' - the channels used to index the table (the '''Hash''' fields are internal axis identifiers, not user-set).
* '''Action''' - what the looked-up value controls; leave 'None' to use the table only for monitoring or as an input to something else.
* '''PWM Output Pin''' / '''PWM Frequency''' / '''PWM Duty if error''' - used when Action is PWM Output; the error duty is the safe fallback when the axes are invalid.

= User counters =
Up to four user counters (user counter x, x = 1–4). Each is an integer value that increments, decrements, and resets from button inputs, optionally wrapping between a minimum and maximum. Use one as a manually-stepped selector — a map switch, boost level, launch RPM step, etc. — whose value feeds other functions.

Per-counter fields, identical for every counter: '''Minimum/Maximum value''' and '''Wrap around''' bound the count, and the '''Increment''' / '''Decrement''' / '''Reset''' switch inputs (with their pin modes) step it.

All four counters are identical; only their index differs.

= Math channels =
Up to eight math channels (math channel x, x = 1–8). Each applies a selectable '''Function''' to up to five '''inputs''', where each input is either a constant '''Value''' or a '''Variable''' (any channel). Optional exponential '''Averaging''' smooths a noisy result (0 = none, 90–95 for noisy signals). The output becomes a channel you can log or feed into tables, logic outputs and CAN messages. The per-input '''Hash''' fields are internal identifiers, not user-set.

All eight channels are identical; only their index differs.

= Bit builders =
Up to eight bit builders (bit builder x, x = 1–8). Each assembles a single integer from up to eight bits, where every bit is either '''Fixed''' or driven by a '''Variable''' — any non-zero variable value sets that bit to 1. Use it to pack several on/off signals (typically [[Advanced#Logic outputs|logic outputs]]) into one value for CAN transmission or table lookup.

All eight builders are identical; only their index differs.

= Analog Multi-Switch =
Up to four analog multi-switches (analog multi-switch x, x = 1–4). Each reads one analog input and resolves its voltage to a discrete '''Position''' via the position curve — the standard way to read a multi-position rotary switch (for example a 5-position map selector) over a single wire using a resistor ladder.

All four switches are identical; only their index differs.

= Logic outputs =
Up to ten logic outputs (logic output x, x = 1–10) — the ECU's general-purpose programmable on/off logic. Each output evaluates up to five '''conditions''' (comparisons on any channel), combines them with the selected boolean '''Conditions logic''', and when the result is true drives an output '''pin''' and/or takes an engine '''action''' (do nothing, cut fuel, cut spark, cut both, kill the engine, or limit RPM). '''Turn on/off delay''' debounce the result and '''Inverted''' flips it (active when conditions are NOT met). Set the pin to NONE to use the result virtually (e.g. as a [[Advanced#Bit builders|bit builder]] input).

All ten outputs are identical; only their index differs.

Config:Idle

2026-06-06T22:58:36Z

Ogalic:

= Idle settings =
Configuration for engine idle: the target speed, the open- and closed-loop control that holds it, idle ignition timing, and the idle air hardware (IAC solenoid, stepper, or electronic throttle).


== Idle settings ==
Core idle behaviour: how idle is controlled and the conditions under which the ECU decides the engine is idling.


==== Idle control mode ====
See also idleRpmPid

* '''Open Loop + Closed Loop'''
* '''Open Loop'''


==== TPS threshold ====
Below this throttle position, the engine is considered idling. If you have an electronic throttle, this checks accelerator pedal position instead of throttle position, and should be set to 1-2%.


==== Force idle below throttle threshold ====
Force idle STATE below DriveIntent threshold.


==== Force timing only below pedal threshold ====
Force idle ignition (delta target only) below DriverThreshold threshold, only for ignition timing


==== Idle force delayed by DFCO ====
Do not force idle ignition while DFCO is active for either of the above.


==== Delta target rpm smoothing factor ====
Smoothing factor for delta target rpm ignition adjustment


==== RPM upper limit ====
How far above idle speed do we consider idling, i.e. coasting detection threshold.
For example, if target = 800, this param = 200, then anything below 1000 RPM is considered idle.


==== RPM deadzone ====
If the RPM closer to target than this value, disable closed loop idle correction to prevent oscillation


==== Max vehicle speed ====
Above this speed, disable closed loop idle control. Set to 0 to disable (allow closed loop idle at any speed).


== Idle overrides ==
Optional tables and ramps that override normal idle fuel and timing: separate idle/coasting ignition and VE tables, return-to-idle target ramping, and cranking-taper handling.


==== Separate idle ignition table ====
This activates a separate ignition timing table for idle conditions, this can help idle stability by using ignition retard and advance either side of the desired idle speed. Extra advance at low idle speeds will prevent stalling and extra retard at high idle speeds can help reduce engine power and slow the idle speed.


==== Use idle ignition table while coasting ====
When enabled, the idle ignition table is also applied during coasting (overrun), not only at idle. Limited by [[Idle#Max RPM for idle advance while coasting|Max RPM for idle advance while coasting]].


==== Max RPM for idle advance while coasting ====
Maximum RPM for which idle advance while coasting is enabled


==== Separate idle VE table ====
This activates a separate fuel table for Idle, this allows fine tuning of the idle fuelling.


==== Override Idle VE table load axis ====
Allows you to change the default load axis used for the VE table, which is typically MAP (manifold absolute pressure).

* '''None'''
* '''MAP'''
* '''TPS'''
* '''PERCENT BARO'''


==== Ramp target RPM on return to idle ====
Ramp the idle target down from the entry threshold over N seconds when returning to idle. Helps prevent overshooting (below) the idle target while returning to idle from coasting.

* '''no'''
* '''yes'''


==== Ramp target duration ====
idle return target ramp duration


==== Separate idle tables for cranking taper ====
This uses separate ignition timing and VE tables not only for idle conditions, also during the postcranking-to-idle taper transition (See also afterCrankingIACtaperDuration).


==== Separate coasting idle table ====
Override the IAC position during overrun conditions to help reduce engine breaking, this can be helpful for large engines in light weight cars or engines that have trouble returning to idle.


== Open Loop Idle ==
Open-loop idle adders. Each active accessory load (A/C, transmission in gear, fans, CAN idle-up) raises the base idle air and/or the target RPM so the engine does not sag when the load engages.


==== A/C adder ====
Additional idle % while A/C is active


==== A/C RPM target ====
Idle target speed when A/C is enabled. Some cars need the extra speed to keep the AC efficient while idling.


==== Transmission idle up adder ====
Additional idle % while transmission idle up is active


==== Transmission idle up RPM target ====
Idle target speed when transmission idle up is enabled. Some transmissions need extra idle speed when engaged.


==== Fan #1 adder ====
Additional idle % when fan #1 is active. In PWM mode this is scaled according to PWM %


==== Fan #1 RPM target ====
Idle RPM target adder when fan #1 is active. Raises the idle RPM target so the closed-loop PID does not fight the open-loop IAC adder.


==== Fan #2 adder ====
Additional idle % when fan #2 is active. In PWM mode this is scaled according to PWM %


==== Fan #2 RPM target ====
Idle RPM target adder when fan #2 is active. Raises the idle RPM target so the closed-loop PID does not fight the open-loop IAC adder.


==== CAN idle-up target RPM adder ====
can box idle up demand


==== CAN idle-up % adder ====
can box idle up demand %


== Closed Loop Idle ==
Closed-loop idle PID. The ECU trims idle air (IAC duty or ETB angle) to hold the target RPM, working on top of the open-loop position. See https://content.epicefi.com/wiki/index.php/Guides:PID_Control for tuning the gains.


==== P gain ====
Proportional value.
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control


==== I gain ====
Integral value
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control.


==== D gain ====
Derivative value
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control.


==== Min ====
PID controller output minimum duty value.


==== Max ====
PID controller output maximum duty value.


==== iTerm Min ====
iTerm min value


==== iTerm Max ====
iTerm max value


==== PID Extra for low RPM ====
Increases PID reaction for RPM<target by adding extra percent to PID-error


==== Use PID output gain table ====
This flag allows to use a special 'PID Multiplier' table (0.0-1.0) to compensate for nonlinear nature of IAC-RPM controller


== ETB idle settings ==
Idle settings specific to electronic throttle (ETB) cars, where idle air is metered by the throttle plate itself instead of a separate IAC valve.


==== ETB idle maximum angle ====
This sets the range of the idle control on the ETB. At 100% idle position, the value specified here sets the base ETB position.


== Dashpot emulation ==
Dashpot (coasting-to-idle) emulation. Adds a temporary slug of idle air when dropping back to idle from a coast, then holds it and decays it away, softening the transition and preventing stall — emulating a mechanical throttle dashpot. Separate values are provided for when A/C is on.


==== Dashpot coasting-to-idle Initial idle Adder ====
This value is an added for base idle value. Idle Value added when coasting and transitioning into idle.


==== Dashpot coasting-to-idle Hold time ====
How long initial idle adder is held before starting to decay.


==== Dashpot coasting-to-idle Decay time ====
How long it takes to remove initial IAC adder to return to normal idle.


==== Dashpot coasting-to-idle Initial idle Adder(AC ON) ====
This value is an added for base idle value(AC ON). Idle Value added when coasting and transitioning into idle.


==== Dashpot coasting-to-idle Hold time(AC ON) ====
How long initial idle adder is held before starting to decay(AC ON).


==== Dashpot coasting-to-idle Decay time(AC ON) ====
How long it takes to remove initial IAC adder to return to normal idle(AC ON).


== Ignition idle settings ==
Idle ignition timing. Lets idle be stabilised with spark as well as air — advancing to recover from a sag and retarding to bleed off speed, for faster correction than air alone.


==== Open loop idle timing (RPM-error) ====
Use Idle Target Error Delta timing curve


==== Include corrections in idle timing ====
If enabled, adds the result from the RPM-error curve to the corrected idle advance. If disabled, it discards all corrections (IAT, CLT, PID etc.) and uses the curve value directly.


=== Closed loop ignition timing (PID) ===
Closed-loop idle ignition timing: a fast PID that adjusts spark advance around the idle target for quick correction, working alongside the slower air-based idle PID.


==== Enable PID control ====
Gain is in degrees advance per rpm away from target, a good starting point is 0.1 = 10 deg per 100 rpm


==== P gain ====
Proportional value.
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control


==== I gain ====
Integral value
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control.


==== D gain ====
Derivative value
See https://content.epicefi.com/wiki/index.php/Guides:PID_Control.


==== Min adjustment (retard) ====
PID controller output minimum duty value.


==== Max adjustment (advance) ====
PID controller output maximum duty value.


==== Soft entry time ====
When entering idle, and the PID settings are aggressive, it's good to make a soft entry upon entering closed loop


= Idle hardware =
Physical idle air hardware: the IAC solenoid or stepper outputs and their drive settings. Electronic-throttle cars meter idle air through the throttle plate instead — see [[Idle#ETB idle settings|ETB idle settings]].


== Solenoid ==
PWM idle air control (IAC) solenoid valve output(s). Supports a single valve or a Subaru/BMW-style double solenoid.


==== Idle Solenoid Primary output ====
Primary output pin driving the PWM idle air control (IAC) solenoid valve.

To find the actual value for your hardware, see [[Hardware]].


==== Double Solenoid Mode ====
Subaru/BMW style where default valve position is somewhere in the middle. First solenoid opens it more while second can close it more than default position.


==== Idle Solenoid Secondary output ====
Second output pin for double-solenoid idle valves (some Subaru and Mazda), where one solenoid opens the valve further and the other closes it past the default position. Only used in [[Idle#Double Solenoid Mode|Double Solenoid Mode]].

To find the actual value for your hardware, see [[Hardware]].


==== Idle Solenoid output(s) Mode ====
Output mode for the idle solenoid pin(s). See [[Hardware:ECU output mode selection|ECU output mode selection]].


==== Idle Solenoid Frequency ====
PWM frequency for the idle air control solenoid output. Match it to your valve: too low buzzes audibly and meters air unevenly, too high and the valve cannot respond. Two-wire IAC solenoids are typically driven around 200–300 Hz.


= Idle target RPM =
Target idle RPM as a function of coolant temperature. A cold engine targets a higher idle, tapering down to the warm idle as it heats up.


= Idle open loop position =
Open-loop idle air position (IAC % or stepper steps) versus coolant temperature. This is the base feed-forward opening; closed-loop control trims around it.


= Idle cranking position =
Idle air position held while cranking, versus coolant temperature. Sets how far the valve opens to get the engine to fire, before the crank-to-run taper takes over.


==== ETB idle maximum angle ====
This sets the range of the idle control on the ETB. At 100% idle position, the value specified here sets the base ETB position.


== Cranking Idle Valve Curve ==
2D curve — X: Coolant (-40 to 120), Y: Percent (0 to 100).


= Idle after start (crank-to-run) taper =
After the engine starts, the extra cranking idle air is tapered out over a number of engine cycles (versus coolant temperature) down to the running idle position.


== Idle valve Crank-to-Run Taper ==
2D curve — X: Coolant (-40 to 120), Y: cycles (0 to 500).


= Idle PID output gain =
Optional PID output multiplier (0.0–1.0) versus RPM, used to compensate for the non-linear relationship between IAC position and RPM. Enabled by [[Idle#Use PID output gain table|Use PID output gain table]].


= Idle PID error gain =
Extra PID gain applied as a function of RPM error, letting the controller react harder the further idle is from target.


= Coasting idle position override =
Idle air position used during overrun/coasting (versus coolant temperature) when the separate coasting idle table is enabled, used to manage engine braking and return-to-idle.


= Valve force close / stepper re-park =
Gradually drives the idle valve closed and re-parks the stepper once the engine is clearly off-idle (above an RPM and TPS threshold). Prevents manifold pressure leaking through the valve at cruise and resets accumulated stepper step-loss without a full homing cycle.


==== Force close: RPM threshold ====
Gradually close the idle valve and re-park the stepper when RPM is above this value AND TPS is above idleValveForceCloseTps. Prevents manifold pressure leakage through the valve at cruise, and resets accumulated stepper step-loss errors. Set to 0 to disable.


==== Force close: delay (s) ====
Seconds to wait after RPM and TPS conditions are both met before beginning to close the idle valve. Prevents closing on brief throttle blips.


==== Force close: TPS taper start (%) ====
TPS at which the idle valve starts closing toward zero (taper start). Used together with idleValveForceCloseRpm and idleValveForceCloseTpsEnd.


==== Force close: TPS taper end (%) ====
TPS at which the idle valve reaches fully closed and the stepper is re-parked (taper end). Position is linearly interpolated from current to zero between idleValveForceCloseTps and this value. Should be greater than idleValveForceCloseTps.


==== Force close: re-park overstep (steps) ====
Number of extra steps to overstep toward closed when re-parking after force-close. Compensates for stepper drift without needing the full startup homing sequence. 5 is a good starting point.


= Open loop ignition idle timing (RPM-error) =
Open-loop idle timing curve: ignition advance/retard as a function of how far RPM is from the idle target. Enabled by [[Idle#Open loop idle timing (RPM-error)|Open loop idle timing (RPM-error)]].


== Idle Target Error ==
2D curve — X: Delta (-500 to 500), Y: Deg (-30 to 30).


= Idle fuel table =
Separate VE/fuel table used at idle when [[Idle#Separate idle VE table|Separate idle VE table]] is enabled, for fine control of idle fuelling independent of the main table.


= Idle ignition table =
Separate ignition timing table used at idle when [[Idle#Separate idle ignition table|Separate idle ignition table]] is enabled. Advance at low idle speed prevents stalling; retard at high idle speed bleeds off power to settle the idle.


= Rotational idle =
Rotational idle (a race/anti-lag-style lumpy idle): deliberately cuts spark and/or fuel in a rotating pattern at idle to produce a distinctive idle sound, with three accumulators that shift the pattern for different exhaust notes. Can be engaged manually by pin or automatically by TPS/CLT.

==== Add/Remove air percentage ====
Percentage of air to add/remove to the idle.


==== Override ETB Idle Authority (0 to disable override) ====
Override the ETB authority for the rotational idle.


==== Fuel Multiplier (1.5 = 150% , 0 to 2.5) ====
Rotational idle fuel multiplier


==== Rotational Absolute Timing (-30 = 30 ATDC, 0 = original timing, 10 - -100) ====
Rotational idle absolute ignition (-20 = atdc 20 degrees)


==== Old rotational idle logic (true = old, false = new) - see tooltip ====
Old rotational idle logic, New logic is based on global spark counter, the three layers of accumulators and adders run at the same time, offset shifts the pattern forward or backward with relation to each other, this should allow different sound patterns by combining different offsets;


==== Rotational Fuel Offset (should be 0, this shifts fuel cut in relation to ignition signal) ====
Rotational idle fuel offset (should be 0, this shifts fuel cut in relation to ignition signal). At 0, in sequential injection/ignition the fuel pulse is cut before the ignition pulse. so fuel is not wasted.

Raises idle air and/or target RPM when an automatic transmission is put in gear (switch input), so the engine does not sag under the torque-converter load.


==== Transmission idle up switch ====
Switch input that signals the transmission is in gear, activating transmission idle-up.

To find the actual value for your hardware, see [[Hardware]].

==== Idle control mode ====
See also idleRpmPid

* '''Open Loop + Closed Loop'''
* '''Open Loop'''


==== TPS threshold ====
Below this throttle position, the engine is considered idling. If you have an electronic throttle, this checks accelerator pedal position instead of throttle position, and should be set to 1-2%.


==== Force idle below throttle threshold ====
Force idle STATE below DriveIntent threshold.


==== Force timing only below pedal threshold ====
Force idle ignition (delta target only) below DriverThreshold threshold, only for ignition timing


==== Idle force delayed by DFCO ====
Do not force idle ignition while DFCO is active for either of the above.


==== Delta target rpm smoothing factor ====
Smoothing factor for delta target rpm ignition adjustment


==== RPM upper limit ====
How far above idle speed do we consider idling, i.e. coasting detection threshold.
For example, if target = 800, this param = 200, then anything below 1000 RPM is considered idle.


==== RPM deadzone ====
If the RPM closer to target than this value, disable closed loop idle correction to prevent oscillation


==== Max vehicle speed ====
Above this speed, disable closed loop idle control. Set to 0 to disable (allow closed loop idle at any speed).


== Idle overrides ==


==== Separate idle ignition table ====
This activates a separate ignition timing table for idle conditions, this can help idle stability by using ignition retard and advance either side of the desired idle speed. Extra advance at low idle speeds will prevent stalling and extra retard at high idle speeds can help reduce engine power and slow the idle speed.


==== Use idle ignition table while coasting ====


==== Max RPM for idle advance while coasting ====
Maximum RPM for which idle advance while coasting is enabled


==== Separate idle VE table ====
This activates a separate fuel table for Idle, this allows fine tuning of the idle fuelling.


==== Override Idle VE table load axis ====
Allows you to change the default load axis used for the VE table, which is typically MAP (manifold absolute pressure).

* '''None'''
* '''MAP'''
* '''TPS'''
* '''PERCENT BARO'''


==== Ramp target RPM on return to idle ====
Ramp the idle target down from the entry threshold over N seconds when returning to idle. Helps prevent overshooting (below) the idle target while returning to idle from coasting.

* '''no'''
* '''yes'''


==== Ramp target duration ====
idle return target ramp duration


==== Separate idle tables for cranking taper ====
This uses separate ignition timing and VE tables not only for idle conditions, also during the postcranking-to-idle taper transition (See also afterCrankingIACtaperDuration).


==== Separate coasting idle table ====
Override the IAC position during overrun conditions to help reduce engine breaking, this can be helpful for large engines in light weight cars or engines that have trouble returning to idle.


== Open Loop Idle ==


==== A/C adder ====
Additional idle % while A/C is active


==== A/C RPM target ====
Idle target speed when A/C is enabled. Some cars need the extra speed to keep the AC efficient while idling.


==== Transmission idle up adder ====
Additional idle % while transmission idle up is active


==== Transmission idle up RPM target ====
Idle target speed when transmission idle up is enabled. Some transmissions need extra idle speed when engaged.


==== Fan #1 adder ====
Additional idle % when fan #1 is active. In PWM mode this is scaled according to PWM %


==== Fan #1 RPM target ====
Idle RPM target adder when fan #1 is active. Raises the idle RPM target so the closed-loop PID does not fight the open-loop IAC adder.


==== Fan #2 adder ====
Additional idle % when fan #2 is active. In PWM mode this is scaled according to PWM %


==== Fan #2 RPM target ====
Idle RPM target adder when fan #2 is active. Raises the idle RPM target so the closed-loop PID does not fight the open-loop IAC adder.


==== CAN idle-up target RPM adder ====
can box idle up demand


==== CAN idle-up % adder ====
can box idle up demand %


== Closed Loop Idle ==


==== P gain ====
Proportional value.

==== iTerm Min ====
iTerm min value


==== iTerm Max ====
iTerm max value


==== PID Extra for low RPM ====
Increases PID reaction for RPM<target by adding extra percent to PID-error


==== Use PID output gain table ====
This flag allows to use a special 'PID Multiplier' table (0.0-1.0) to compensate for nonlinear nature of IAC-RPM controller


== ETB idle settings ==


==== ETB idle maximum angle ====
This sets the range of the idle control on the ETB. At 100% idle position, the value specified here sets the base ETB position.


== Dashpot emulation ==


==== Dashpot coasting-to-idle Initial idle Adder ====
This value is an added for base idle value. Idle Value added when coasting and transitioning into idle.


==== Dashpot coasting-to-idle Hold time ====
How long initial idle adder is held before starting to decay.


==== Dashpot coasting-to-idle Decay time ====
How long it takes to remove initial IAC adder to return to normal idle.


==== Dashpot coasting-to-idle Initial idle Adder(AC ON) ====
This value is an added for base idle value(AC ON). Idle Value added when coasting and transitioning into idle.


==== Dashpot coasting-to-idle Hold time(AC ON) ====
How long initial idle adder is held before starting to decay(AC ON).


==== Dashpot coasting-to-idle Decay time(AC ON) ====
How long it takes to remove initial IAC adder to return to normal idle(AC ON).


== Ignition idle settings ==


==== Open loop idle timing (RPM-error) ====
Use Idle Target Error Delta timing curve


==== Include corrections in idle timing ====
If enabled, adds the result from the RPM-error curve to the corrected idle advance. If disabled, it discards all corrections (IAT, CLT, PID etc.) and uses the curve value directly.


=== Closed loop ignition timing (PID) ===


==== Enable PID control ====
Gain is in degrees advance per rpm away from target, a good starting point is 0.1 = 10 deg per 100 rpm


==== P gain ====

Ogalic: /* Cranking */

= Cranking =
The cranking menu handles fuel and ignition during cranking conditions. Cranking conditions are defined as RPM below the cranking threshold.

= Cranking settings =

==== Cranking RPM limit ====
This sets the RPM limit below which the ECU will use cranking fuel and ignition logic, typically this is around 350-450rpm.
set cranking_rpm X

=== Fuel ===

==== Injection mode ====
This is the injection strategy during engine start. See [[Config:Fuel#Mode|Fuel settings]] for more detail. It is suggested to use "Simultaneous".

==== Cranking fuel table ====
For cranking either use the specified fixed base fuel mass, or use the normal running math (VE table).

=== Ignition ===

==== Timing Advance mode ====

* '''Constant mode''' - Timing is automatically tapered to running as RPM increases.

* '''Table mode''' - The "Cranking ignition advance" table is used directly.

==== Fixed cranking advance ====
Ignition advance angle used during engine cranking, 5-10 degrees will work as a base setting for most engines.

There is tapering towards running timing advance.

==== Fixed Cranking Dwell ====
Dwell duration while cranking

=== Advanced ===

==== Flood clear ====
When enabled if TPS is held above 95% no fuel is injected while cranking to clear excess fuel from the cylinders.

==== Faster engine spin-up ====
If enabled, try to fire the engine before a full engine cycle has been completed using RPM estimated from the last 90 degrees of engine rotation. As soon as the trigger syncs plus 90 degrees rotation, fuel and ignition events will occur. If disabled, worst case may require up to 4 full crank rotations before any events are scheduled.

==== Use Advance Corrections for cranking ====
This enables the various ignition corrections during cranking (IAT, CLT and PID idle).

You probably don't need this.

==== Separate Flex Fuel cranking table ====
Enable a second cranking table to use for E100 flex fuel, interpolating between the two based on flex fuel sensor.

= Cranking Air Amount vs CLT =
If electronic throttle is used, this table defines the limit of the blade angle that the idle controller authority has, the idle controller will not open the throttle valve more than this amount.

If not using electronic throttle, this table defines the maximum duty or stepper range.

==== ETB idle maximum angle ====
This sets the range of the idle control on the ETB. At 100% idle position, the value specified here sets the base ETB position.

= After-start enrichment (ASE) =
After start Enrichment, or ASE, is an initial, short lived duration of extra fuel enrichment to help the engine stabilise after cranking and initial fire-up. This table defines the fuel multiplier for ASE.

= Priming pulse =

==== Disable fuel pump prime on power on ====
This disables the fuel pump prime.

==== Disable injector prime pulse ====
Do not fire the initial priming pulse of the injectors.

==== Fuel pump prime delay after power ====
How long to delay fuel pump prime from ignition-on detection

==== Injector Priming delay (after fuel pump delay) ====
Delay to allow fuel pressure to build before firing the priming pulse.

==== Priming pulse fuel mass ====
This is the fuel mass in mg that will be injected on priming pulse.

= Cranking Base Fuel (Engine Cycle vs CLT) =
This is the percentage of required fuel, 100% means inject fuel for stoichometric combustion. This is then modified by the multipliers for IAT, TPS ect, to give the final cranking pulse width.
A reasonable starting point is 70%.

= CLT Cranking Fuel Multiplier (E0) =
This is the cranking fuel multiplier at zero ethanol content (also used when no flex fuel is used).

= CLT Flex Cranking Fuel Multiplier (E85) =
This is the cranking fuel multiplier at 85% ethanol content (requires [[Flex Fuel]] sensor).

= CLT Cranking ignition advance =
Optional timing advance table for cranking, see [[Config:Cranking#Timing Advance mode|Timing Advance mode.]]

The Ignition menu is used to configure all aspects of ignition control, including [[Knock Control]].

= Ignition advance =
This is the main ignition table, in degrees BTDC before any corrections. This defines the baseline ignition angle.

= CLT timing correction =
This table defines the coolant temperature ignition correction. Used to prevent knock on very hot engines.

= IAT timing correction =
This table defines the intake air temperature ignition correction. Use this table to prevent knock on bad intake setups or poor charge air cooling.

= Dwell Table =
This table defines the dwell time for the ignition system, defined in miliseconds. This table is defined in the Y axis by the battery voltage, used to correct for poor spark during cranking by introducing more dwell time.

= Ignition Hardware Angle Correction =
Compensates for trigger delay due to belt stretch, or other electro-mechanical issues. Also used to compensate for the ignition system delay.
{{Warning|This is correction in degrees by RPM. Beware that raising this value is directly added to the advance and this advances ignition timing!}}

= Ignition Hardware =

==== Spark ====
If ignition is enabled.

==== Mode ====

* '''Single coil''' - Simple distributor

* '''Individual coils''' - One coil per cylinder (coil-on-plug or coil-near-plug). Requires sequential mode or [[Config:Setup#Guess sync RPM threshold(rpm)|phase guessing]].

* '''Wasted spark''' - Fires pairs of cylinders together, either one coil per pair of cylinders or one coil per cylinder. Choose this if you have coil-on-plug or coil-near-plug but no camshaft sensor or you do not want to use [[Config:Setup#Guess sync RPM threshold(rpm)|phase guessing]]. Enable [[Config:Ignition#Individually wired Wasted Spark|Individually wired Wasted Spark]] for such a setup.

* '''Two distributors''' - A pair of distributors, found on some BMW, Porsche, Toyota and other engines.

==== Dwell duty cycle limit ====
Clamp dwell duration to this % of time slot (100=do not clamp)

Just like injectors, ignition coils have duty cycle, if duty cycle gets close to or exceeds 100%, ignition stops working

==== Individually wired Wasted Spark ====
This is needed if your coils are individually wired (COP) and you wish to use batch ignition (Wasted Spark).

==== Override ignition table load axis ====
Override the Y axis (load) value used for the ignition table.
{{Warning Mild|Advanced users only: If you aren't sure you need this, you probably don't need this.}}

==== Timing Mode ====

* '''Dynamic''' - Ignition behaves normally using the ignition table and any corrections applied to it.

* '''Static''' - Fixes the timing to the value set below.
{{Warning Mild|Only used fixed timing to verify trigger configuration with a timing light, never during normal driving conditions.}}

==== Fixed Timing ====
The fixed timing value when fixed timing is used.
{{Warning Mild|Only used fixed timing to verify trigger configuration with a timing light, never during normal driving conditions.}}

=== Ignition Outputs ===

==== Ignition Output Mode ====
See [[Hardware:ECU output mode selection|ECU output mode selection]].

==== Ignition Output x ====
This is the physical output pin for the ignition output.

To find the actual value for your hardware, see [[Hardware]].

=== Enable/Disable ignition outputs ===

==== Ignition x disable ====
This disables the specified ignition output. Used for testing/debugging.

= Ignition Table Switch =
This is used for ignition table switching.

== Ignition Table Switch x Settings ==

==== Ignition Table Switch x Pin ====
This is the pin to toggle the table switch.

==== Ignition Table Switch x Pin Mode ====
See [[Hardware:ECU input mode selection|ECU input mode selection]].

==== Ignition Table Switch x Parameter ====
This changes the ignition table switch X axis parameter

==== Ignition Table Switch x Blend Mode ====
Blend mode adds or multiplies the switch table with base, default is switch.

==== Ignition Table Switch x Y axis override ====
This changes the ignition switch table Y axis.{{Warning Mild|Advanced users only: If you aren't sure you need this, you probably don't need this.}}

== Ignition Table Switch x ==
This is the ignition switch OR blend table as defined by [[Config:Ignition#Ignition Table Switch x Blend Mode|Ignition Table Switch x Blend Mode]]

= Cylinder Ignition Trim =
This is individual cylinder ignition trim.

== Ignition trim cyl x (deg) ==
This table trims the ignition by the specified number of degrees in relation to load.

== Switchable Ignition Adders ==

==== Ignition adder x pin ====
This is the physical input pin that enables the ignition adder.

==== Ignition adder x pin mode ====
See [[Hardware:ECU input mode selection|ECU input mode selection]].

==== Ignition adder x value ====
Random ignition adder x value (-60 to 60 degrees)

= Knock Control =
This is the epicEFI software-defined knock control. The knock control on epicEFI is software-based, ie. the software does the raw sensor sampling, the digital filtering, [[wikipedia:Band-pass_filter|bandpassing]] and windowing (only listening to knock on specific crank angles).

Special thanks to [https://github.com/mck1117 Matthew Kennedy] for implementing this feature and testing it on his engines (of which he destroyed a few in the process).
{{Warning|The Knock retard functionality is a tool to detect engine knock, but with wrong settings it can cause engine damages. Use with caution!}}

==== Software Knock Sense Enable ====
Enable or disable knock control.

==== Linear scale ====
Changes knock sensor values from logarithmic (dB) to a linear scale starting at 0.

==== Linear scale gain ====
~~PLACEHOLDER~~

==== Cylinder Bore ====
Cylinder diameter in mm

==== Estimated Knock Frequency ====
If you want to define the knock frequency manually, use this input field. If this field is non-zero, the [[Config:Ignition#Cylinder Bore|Cylinder Bore]]-based knock frequency calculation is ignored.

==== Detection mode ====

* '''First harmonic''' - The basic calculated or defined frequency

* '''Second harmonic''' - The first harmonic frequency, but doubled. This is possible because the pressure wave can fit two half-waves across the bore instead of one. It’s weaker than the first harmonic, but its much cleaner (less contaminated by valvetrain, piston slap, mechanical noise) and extremely useful at high RPM where the fundamental gets buried in engine noise.

==== Detection Window Start ====
The windowed knock control start window in degrees BTDC.

==== Sampling Duration ====
The angular duration of the knock window. Defined in crankshaft angle.

==== Enable Knock Spectrogram ====
Available via TS Plugin see https://rusefi.com/s/knock

==== Enable Knock Spectrogram Filter ====
This defines a filter for the spectrogram.

==== Knock Spectrum Sensitivity ====
This defines the relative sensitivity of the knock spectrogram.

=== Select the nearest sensor for each cylinder ===

==== Cylinder x ====
This defines what cylinder is closes the the physical knock sensor.

=== Response ===

==== knockRetardAggression ====
Ignition timing to remove when a knock event occurs. Advice: 5% (mild), 10% (turbo/high comp.), 15% (high knock, e.g. GDI), 20% (spicy lump),

==== knockRetardReapplyRate ====

After a knock event, reapply fuel at this rate.

==== knockFuelTrim ====
Fuel trim when knock, max 30%

==== knockSuppressMinTps ====
Below TPS value all knock suppression will be disabled.

==== knockSuppressMinRpm ====
Below RPM value all knock suppression will be disabled

== Knock threshold ==

Knock sensor output knock detection threshold depending on current RPM. This is the threshold above which engine noise is considered as knock and [[Config:Ignition#Response|response]] starts to get applied.

= Max knock retard =
This table defines the maximum allowed knock retard.

= Per cylinder knock gains =
This table defines the per-cylinder knock gain (used when lots of cylinders share a single knock sensor).

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use batch ====
Enable batch [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use simultaneous ====
Enable simultaneous [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Cycles ====
Switch fuel strategy every this many cycles of the engine.

==== Min RPM ====
Minimum RPM for the tool to run.

== Injector Advance Assisted Tuning ==

epicEFI firmware includes the '''Injector Advance Tuning Tool'''. This enables the optimization of the injector close angle (also called end-of-injection) by offsetting it on a schedule. This enables you to test out the injection end angle by listening how the engine runs.

Let's say the injector needs to close at 90 degrees crankshaft angle and the tool is enabled and configured for -10 and +10 degrees. The injection end-of-injection will be changed by each step each number of cycles from 80 to 100 degrees.

This is the integral component of the short term fuel trim.

== Short term fuel trim Add Authority (+) ==
Define how much fuel the short-term trim system is allowed to add at a given RPM vs. load (MAP/AFR) point.

* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

This is the master switch for the tool.

==== Use sequential ====

==== Cycles ====

==== Min RPM ====
Minimum RPM for the tool to run.

== Injector Advance Assisted Tuning ==

epicEFI firmware includes the '''Injector Advance Tuning Tool'''. This enables the optimization of the injector close angle (also called end-of-injection) by offsetting it on a schedule. This enables you to test out the injection end angle by listening how the engine runs.

Let's say the injector needs to close at 90 degrees crankshaft angle and the tool is enabled and configured for -10 and +10 degrees. The injection end-of-injection will be changed by each step each number of cycles from 80 to 100 degrees.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====

This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use batch ====
Enable batch [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use simultaneous ====
Enable simultaneous [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Cycles ====
Switch fuel strategy every this many cycles of the engine.

==== Min RPM ====
Minimum RPM for the tool to run.

== Injector Advance Assisted Tuning ==

epicEFI firmware includes the '''Injector Advance Tuning Tool'''. This enables the optimization of the injector close angle (also called end-of-injection) by offsetting it on a schedule. This enables you to test out the injection end angle by listening how the engine runs.

Let's say the injector needs to close at 90 degrees crankshaft angle and the tool is enabled and configured for -10 and +10 degrees. The injection end-of-injection will be changed by each step each number of cycles from 80 to 100 degrees.

This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

== Injector Advance Assisted Tuning ==

epicEFI firmware includes the '''Injector Advance Tuning Tool'''. This enables the optimization of the injector close angle (also called end-of-injection) by offsetting it on a schedule. This enables you to test out the injection end angle by listening how the engine runs.

Let's say the injector needs to close at 90 degrees crankshaft angle and the tool is enabled and configured for -10 and +10 degrees. The injection end-of-injection will be changed by each step each number of cycles from 80 to 100 degrees.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

== Injector Advance Assisted Tuning ==

epicEFI firmware includes the '''Injector Advance Tuning Tool'''. This enables the optimization of the injector close angle (also called end-of-injection) by offsetting it on a schedule. This enables you to test out the injection end angle by listening how the engine runs.

Let's say the injector needs to close at 90 degrees crankshaft angle and the tool is enabled and configured for -10 and +10 degrees. The injection end-of-injection will be changed by each step each number of cycles from 80 to 100 degrees.

This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use batch ====

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use batch ====
Enable batch [[Config:Fuel#Mode|fuel mode]] into the scheduled switching.

==== Use simultaneous ====
Enable simultaneous [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Cycles ====
Switch fuel strategy every this many cycles of the engine.

==== Min RPM ====
Minimum RPM for the tool to run.

Ogalic: /* Injector deadtime assisted tuning */

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the [[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]] to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Use batch ====
Enable batch [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Use simultaneous ====
Enable simultaneous [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Cycles ====
Switch fuel strategy every this many cycles of the engine.

==== Min RPM ====
Minimum RPM for the tool to run.

This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems, or you want to limit the minimum pulsewidth. Do not use otherwise.}}

== Injector deadtime assisted tuning ==

epicEFI firmware includes an '''Injector Deadtime Tuning Tool''' that works by alternating between sequential injection and batch injection on a schedule.

This method works because switching between these two modes changes the number of injection events per engine cycle. In batch mode, the injector fires '''twice per cycle''', while in sequential mode it fires '''once per cycle'''.

In both cases, the total amount of fuel delivered per cycle remains the same. The difference is that in batch mode the fuel is split into two injection events, whereas in sequential mode it is delivered in a single event. Since injector deadtime is added to every injection event, the total added deadtime per cycle differs between the two modes.

If the deadtime values are not accurate, switching between batch and sequential injection will result in a measurable change in AFR at the exhaust.

The epicEFI Injector Deadtime Tuning Assist automatically switches between sequential and batch modes on a set schedule, allowing you to log the AFR difference. You can then adjust the deadtime table until no AFR change is observed between the two modes, indicating that the injected fuel quantity is consistent in both cases.

It’s advisable to disable [[Config:Fuel#Short term fuel trim Setup|short-term fuel trims]] and to run this test with the engine fully warmed up.

At first, the engine may struggle to stay running when the mode switch occurs. This is expected if your deadtime values are off, since those inaccuracies are usually already “hidden” in the VE table.

If the engine goes too lean and won’t stay running, you can use the '''[[Config:Fuel#Global Fuel Correction (1=100%)|Global Fuel Correction]]''' to richen the mixture enough to keep it alive.

The Global Fuel Correction does not affect injector deadtime. It simply scales the overall fuel delivery, allowing you to keep the engine running while you dial in the correct deadtime values.

==== Enable deadtime tuning cycle ====
This is the master switch for the tool.

==== Use sequential ====
Enable sequential [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Use batch ====
Enable batch [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Use simultaneous ====
Enable simultaneous [[Config:Setup#Fuel strategy|fuel mode]] into the scheduled switching.

==== Cycles ====
Switch fuel strategy every this many cycles of the engine.

==== Min RPM ====
Minimum RPM for the tool to run.

Ogalic: /* Primary Injector Small Pulsewth vs BatV multiplier */

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

Ogalic: /* Primary Injector Small Pulsewidth Table */

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use the [[Config:Fuel#Primary Injector Small Pulsewidth Table|small pulsewidth correction table]] to correct small injector pulse width behaviour.

{{Warning|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Primary Injector Small Pulsewidth Table ==

This is the injector [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]]. This table is used to re-map a small pulsewidth to a bigger one or vice-versa.

This is used to improve idle behaviour and other transient situations.

{{Warning_Mild|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

== Primary Injector Small Pulsewth vs BatV multiplier ==

This is the [[Config:Fuel#Use small pulsewidth correction lookup curve|small pulsewidth correction]] in relation to battery voltage. Small pulse width behavour can change with battery voltage, and this can be used to correct that behaviour.

{{Warning|This feature should only be needed if running very big injectors (>1500cc) and you have idle fueling problems. Do not use otherwise.}}

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== Injection Enabled ====
Fuel Injection is enabled

==== Disable Fuel Pump ====
Disable fuel pump

==== Disable injector prime pulse ====
Do not prime injectors

==== Mode ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== Alpha-N uses IAT density correction ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Override AFR table load axis ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Injection phase control mode ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== Injector flow ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== Injector flow units ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== Fuel rail pressure sensor ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== Injector flow compensation mode ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== Injector reference pressure ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== Use small pulsewidth correction lookup curve ====
Use small pulsewidth lookup

=== Fuel characteristics ===

==== Gasoline (E0) Stoichiometric ratio ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== Ethanol (E100) Stoichiometric ratio ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== Current Ethanol Content ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== Global Fuel Correction (1=100%) ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== Fuel flow rate smoothed alpha (display only) ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== Use absolute fuel pressure for dead time calculation ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== Injection Output x ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== Injector x disable ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== Cylinder x ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== Override the Y axis (load) value used for the injector advance table. ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

==== Override VE table load axis ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== Fuel strategy ====
See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

==== '''Injection Enabled''' ====
Fuel Injection is enabled

==== '''Disable Fuel Pump''' ====
Disable fuel pump

==== '''Disable injector prime pulse''' ====
Do not prime injectors

==== '''Mode''' ====
This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}

==== '''Alpha-N uses IAT density correction''' ====
When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

==== '''Override VE table load axis''' ====
Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== '''Override AFR table load axis''' ====
Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

==== '''Injection phase control mode''' ====
Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

==== '''Injector flow''' ====
This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

==== '''Injector flow units''' ====
Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

==== '''Fuel rail pressure sensor''' ====
Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

==== '''Injector flow compensation mode''' ====
This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

==== '''Injector reference pressure''' ====
This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

==== '''Use small pulsewidth correction lookup curve''' ====
Use small pulsewidth lookup

=== Fuel characteristics ===

==== '''Gasoline (E0) Stoichiometric ratio''' ====
Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

==== '''Ethanol (E100) Stoichiometric ratio''' ====
Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

==== '''Current Ethanol Content''' ====
Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

==== '''Global Fuel Correction (1=100%)''' ====
This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

==== '''Fuel flow rate smoothed alpha (display only)''' ====
This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

==== '''Use absolute fuel pressure for dead time calculation''' ====
This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

==== '''Injection Output x''' ====
This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

==== '''Injector x disable''' ====
This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

==== '''Cylinder x''' ====
Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

==== '''Override the Y axis (load) value used for the injector advance table.''' ====
Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

== Long term fuel trims ==

=== Trim bank 1 ===

=== Long term fuel trim ===

'''Gathering Data'''

Enables lambda sensor long term fuel corrections data gathering into LTFT trim tables

'''Time const'''

Commonly referred as Integral gain.
Time constant for correction while in this cell: this sets responsiveness of the closed loop correction. A value of 30.0 means it will try to make most of the correction within 30 seconds, and a value of 300.0 will try to correct within 5 minutes.
Lower values makes the correction more sensitive, higher values slow the correction down.

'''Max add'''

Maximum % that the long term fuel trim can add

'''Max remove'''

Maximum % that the long term fuel trim can remove

'''Learning deadband'''

When close to correct AFR, pause correction. This can improve stability by not changing the adjustment if the error is extremely small, but is not required.

'''Apply Correction'''

Apply LTFT trims into fuel calculation on top of VE table.
We do not adjust VE table automatically, please click 'Apply to VE' if you want to adjust your VE tables and reset trims.

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

'''Override VE table load axis'''

Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

'''Fuel strategy'''

See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

'''Injection Enabled'''

Fuel Injection is enabled

'''Disable Fuel Pump'''

Disable fuel pump

'''Disable injector prime pulse'''

Do not prime injectors

'''Mode'''

This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}'''Alpha-N uses IAT density correction'''

When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

'''Override VE table load axis'''

Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

'''Override AFR table load axis'''

Override the Y axis (load) value used for the AFR table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

'''Injection phase control mode'''

Defines when fuel is injected relative to the intake valve opening. Options include End of Injection or other timing references.

=== Injector Settings ===

'''Injector flow'''

This is your injector flow at the fuel pressure used in the vehicle.

See units setting below.

'''Injector flow units'''

Select whether to configure injector flow in volumetric flow (default, cc/min) or mass flow (g/s).

'''Fuel rail pressure sensor'''

Select which fuel pressure sensor measures the pressure of the fuel at your injectors.

'''Injector flow compensation mode'''

This is the injector flow compensation mode.

* '''Manifold Referenced Pressure Regulator''' - The car is equipped with a manifold-pressure referenced pressure regulator.
* '''Returnless fuel system''' - The car is equipped with a returnless fuel system (regulator in tank or dead-head system).
* '''Sensed fuel pressure''' - The car is equipped with a fuel pressure sensor.

'''Injector reference pressure'''

This is the pressure at which your injector flow is known.

For example if your injectors flow 400cc/min at 3.5 bar, enter 350 here.

This is gauge pressure reference to atmospheric.

'''Use small pulsewidth correction lookup curve'''

Use small pulsewidth lookup

=== Fuel characteristics ===

'''Gasoline (E0) Stoichiometric ratio'''

Stoichiometric ratio for your primary fuel. When Flex Fuel is enabled, this value is used when the Flex Fuel sensor indicates E0.

E0 = 14.7

E10 = 14.1

E85 = 9.9

E100 = 9.0

'''Ethanol (E100) Stoichiometric ratio'''

Stoichiometric ratio for your secondary fuel. This value is used when the Flex Fuel sensor indicates E100, typically 9.0

'''Current Ethanol Content'''

Some pump gas has ethanol in it. Please adjust this to match what you fill up with.

Use this as default ethanol content for fueling when no flex sensor present.

This will scale Air/Fuel ratios and fueling accordingly.

'''Global Fuel Correction (1=100%)'''

This is the global fuel correction applied to the final pulse width.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

'''Fuel flow rate smoothed alpha (display only)'''

This controls the logged "fuel flow rate" and how much smoothing is applied to that logged value. This has no actual impact on fuelling and the fuelling model.

'''Use absolute fuel pressure for dead time calculation'''

This changes the deadtime calculation to use absolute pressure. Otherwise, differential pressure is used.

== Injection hardware ==

=== Injector Outputs ===

'''Injection Output x'''

This is the physical output pin for the injector output for cylinder x.

=== Injector Enable/Disable ===

'''Injector x disable'''

This menu is used to disable individual injector outputs for troubleshooting.

=== Cylinder Banks - Closed Loop Feedback ===

'''Cylinder x'''

Select which fuel correction bank this cylinder belongs to. Group cylinders that share the same O2 sensor 1.

== Injector Deadtimes (BatV vs fuel pressure) ==
This table defines the [[Injector Dead Time]]. The dead time is the time in milliseconds that it takes for the injector to open and start spraying fuel. It is pressure and voltage dependant.

This table configures the relation of pressure/voltage and deadtime in ms.

== Injector Timing Advance ==
This is injection angle in relation to TDC ignition stroke. Values are ATDC. i.e. If ignition timing is 14 advance, this value has to be -14 to match that event. -400 in this table would put injection well into the intake stroke. 50 here is 50 degrees after TDC compression stroke

'''Override the Y axis (load) value used for the injector advance table.'''

Override the Y axis (load) value used for the injector advance table.

{{Warning|Please note that this is a rudimentary correction and should be used only for troubleshooting and diagnostics.}}

This is your injector flow at the fuel pressure used in the vehicle
See units setting below

'''Secondary injector flow compensation mode'''

None = I have a MAP-referenced fuel pressure regulator
Fixed rail pressure = I have an atmosphere-referenced fuel pressure regulator (returnless, typically)
Sensed rail pressure = I have a fuel pressure sensor

[[File:Fuel menu.jpg|thumb|Fuel menu]]

= Fuel =
This menu is used for any fuel-related configuration and tuning.

This menu enables the configuration of:

* Physical hardware - output pins
* VE tables
* Fuel trims (short and long)
* Lambda control (AFR correction)
* IAT/CLT/Other corrections
* Table switch
* And others...

You can find the individual options below.

= VE Table =
This is the main VE table used for fuel calculations.

'''Override VE table load axis'''

Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

'''Fuel strategy'''

See [[Setup#Fuel strategy|Fuel strategy.]]

= Injector setup =
This menu enables the configuration of the physical injector layout and output configuration

== Injection configuration ==

=== Injection ===

'''Injection Enabled'''

Fuel Injection is enabled

'''Disable Fuel Pump'''

Disable fuel pump

'''Disable injector prime pulse'''

Do not prime injectors

'''Mode'''

This configures the injection model:

* '''Simultaneous''' - All injectors are opened at the same time, with the fuel load being divided over the whole 720 degree cycle (a 4 cylinder engine will squirt 4 times over 720 degrees).
* '''Sequential''' - All injectors are opened at their commanded angle and the cycle is tracked over 720 degrees. Requires [[Cam Sensor]] or [[Setup#Guess sync RPM threshold(rpm)|phase guessing]] to function properly.
* '''Batch''' - Injectors are opened at their commanded angle along with their wasted pair. The same principle as wasted spark.
* '''Single Point''' - The same as simultaneous but with a single channel, with fuel calculations to suit.
{{Warning|Injectors are always wired to their respective cylinders and epicEFI handles the firing order and injector opening. Batch wiring is only needed when the ECU does not have enough outputs to wire single injectors to a single channel.}}'''Alpha-N uses IAT density correction'''

When set to true, it enables intake air temperature-based corrections for Alpha-N tuning strategies.

'''Override VE table load axis'''

Override the Y axis (load) value used for the VE table.

{{Warning|This is for advanced users only. If you aren't sure you need this, you probably don't need this.}}

=== Trim bank 1 ===

=== Long term fuel trim ===

'''Gathering Data'''

Enables lambda sensor long term fuel corrections data gathering into LTFT trim tables

'''Time const'''

Commonly referred as Integral gain.
Time constant for correction while in this cell: this sets responsiveness of the closed loop correction. A value of 30.0 means it will try to make most of the correction within 30 seconds, and a value of 300.0 will try to correct within 5 minutes.
Lower values makes the correction more sensitive, higher values slow the correction down.

'''Max add'''

Maximum % that the long term fuel trim can add

'''Max remove'''

Maximum % that the long term fuel trim can remove

'''Learning deadband'''

When close to correct AFR, pause correction. This can improve stability by not changing the adjustment if the error is extremely small, but is not required.
