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. rusEfi is now a true standalone ECU - the code controls fuel injection, ignition, fuel pump and idle air valve solenoid. Input signals are cranking events and MAF signal, fuel and timing are currently plain and simple table lookups. The main goal of this project is to have perfect code - no hacks, just a straightforward understandable implementation. This combined with open hardware design should really make the next generation of aftermarket engine control units! Right now the next big thing would be to start a couple more of different engines, I am looking for crazy-enough gearheads to join the fun! Step by step, we will make this the next big thing in engine tuning. Now some technical details: - STM32F4DISCOVERY is a development board featuring 32-bit ARM Cortex-M4F core, 1 MB Flash, 192 KB RAM processor with floating-point unit. No more horrors of fixed point math. - ChibiOS/RT real-time operating system is used. Don't let the horrors of peripheral programming hurt you. - Both GCC/Eclipse and IAR toolchains are supported. - KiCad is used to design the circuit boards. - While we are still in the development phase, instead of a one-fits-all PCB we are going to run a set of tiny, function-specific boards like analog inputs or connector board. Plenty of progress was made since the initial release presented on this video: - TunerStudio integration - Multiple engine-specific configurations are supported now. Stay tuned or check our forum Read this article to see how simple all this is. |
