How do you adjust for load?I am in process of development of ECU which will integrated to throttle body 70x70mm board at moment. One sided to make cheaper. I afraid it will take few month to complete.
But I have other simple idea - want to share. May be someone will implement or help me to implement. I believe it is possible create simplest ECU which will calculate injection duration and ignition angle based only on rpm. No other sensors. Small tune can be performed by mechanical fuel pressure regulator. In future it can be separate board which regulate fuel pressure by simple circuit board (themperature and barometric corrections). I would be happy to find someone who can help me in electronics to do this joint project from the scratch and will do all mechanical stuff and testing.
In this case processor should perform 1000th times fewer calculations will be cheap and reliable.
