What is epicEFI?

epicEFI is a fork of the open source engine management firmware rusEFI designed to run on STM32 microcontrollers. Over the years lots of hardware has been designed and manufactured that runs and supports the custom firmware. The manufactured boards support a large set of features, including but not limited to DBW, Knock control, GDI injection and much more. epicEFI runs the vast majority of engines, from single-cylinder two-stroke engines in ignition only mode, to direct-injected, dual DBW GDI BMW V12s.

Advantages to the rusEFI firmware

epicEFI adds various features and nice-to-haves in regards to the mainline rusEFI firmware, namely:

• Unsyncronized fully sequential start without a camshaft sensor
• Universal missing tooth decoders for crankshaft and camshaft position input
