'''Spark'''

Ignition is enabled

'''Mode'''

Single coil = distributor
Individual coils = one coil per cylinder (COP, coil-near-plug), requires sequential mode
Wasted spark = Fires pairs of cylinders together, either one coil per pair of cylinders or one coil per cylinder
Two distributors = A pair of distributors, found on some BMW, Toyota and other engines
set ignition_mode X

'''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.
Advanced users only: If you aren't sure you need this, you probably don't need this.

'''Timing Mode'''

Dynamic uses the timing map to decide the ignition timing
Static timing fixes the timing to the value set below (only use for checking static timing with a timing light).

'''Fixed Timing'''

Fixed timing, useful for TDC testing
