yiap. IF i succeed, i will try to make a webpage about it, because, although there are many projects, the documentation, is very little...

well. the "Sure" thing, is at least when cranking, that if i where to control the ignition as well, i would have a problem... but since the injection, is anyway happening at a closed valve ( i think?? ) and since, during crank, i will anyway supply more fuel, i dont think there will be a b...

so you mean, that etc:

the first cylinder will have good timing,
but then, when its time to spray the second, or even worse, the 4th, the rpm , will have change so much, that it will be dificult to get the correct timing??

hello forum. i was wandering. on electronic controled idle valves, does the valve, completely closes when you press the throttle? or it remains on the position it was before you pressed???

well, it would require , that the engine, makes a full revolution before it starts injecting, but i dont think it will be such a problem?? you can do an asychronous inject, anyway when the crank signal is received??

cool. i am only interested in the injection for now... (ignition will be from the cars ECU).
if i use a segmented disk, and a VR sensor, then the timming will be more aqurate, correct?? (basically i was thinking to use, an optical sensor, with a DIY disk, mounted on camshaft pulley)

well, by now, i have llearned more things. so yes, my question would be "can i run injection on cam signal only" ;) the thing is this: the signal of my distributor is constant 12v, and goes low when "signals" , if i mesure the pulses, then , at iddle , the distributor gives 1000 ...

also. the car uses a 3wire ignition coil. so the coil receives signal from the ecu , to produce the spark...

hello forum. i am in the procces, of converting my car , from carbiratur, to Fuel injection !! .. 1) i would like, for the start, to keep the ignition system, as it is, and not control it from the ECU... 2) now to my problem... My car, is a 1992 Audi 80. (1.6 lt). it seems, that it has no, crank pos...
