microRusEfi seems to be a success, it's now available for sale as kit or fully assembled 4 cylinder ECU with drive by wire.
In the meantime we are making first little steps towards GDI

Got GDI to start - and no plans to develop this further unless anyone would volunteer to be a test mule

I've been playing with this for some time and finally I have at least something I am not embarrassed to share.
So, my idea is that modern MCUs are fast enough so that a relatively high-level programming would be possible. stm32f4discovery gives me 168MHz for about $15,
http://www.chibios.org was the first RTOS I've stumbled upon - this hides most of the lower-level hardware control and even gives me threads.
To begin, at first I was trying to control only fuel or only ignition (with stock ECU controlling the other piece of the puzzle), but soon enough I've realized that I should also control the idle air valve. Crank signal and MAF voltage are currently my only two inputs and I've extracted the fuel map from the stock ECU.
So, currently I control fuel injection and idle. Stock ECU does ignition. This thing starts and I can set idle RPM programmatically.There is still a bug somewhere because things are not super smooth if I push the throttle pedal rapidly, but still
