This project

I am a software developer and cars are just a hobby. Looking at the existing aftermarket engine control units I believe time has come for a simple, clear and usable EFI project. We have boards under $20 running at speeds above 100MHz, we have some great real real-time operation systems - I believe these things combined should make a very simple EFI possible.

In this initial release, this code controls fuel injection and idle valve. Input signals are cranking pulses and MAF voltage, inside there is a table-based lookup for fuel squirt lengths and idle valve PWM which get the engine to the desired idle RPM.

Depends on Chibios:

Not a strong dependence on STM32F4 platform
