I just copied the post from the welcome thread to get the technical stuff started.
I have a Audi Coupé Quattro 20V (7A engine / 5-cylinder) which comes standard with a Hitachi (2-connector) engine control unit and i already upgraded it to the later 4-connector Hitachi version.
that gave me a better idle control valve, a real tps sensor (not just idle and full throttle switch), and i was so able to connect the newer hitachi ecu to the vw dignostics tool. -> vcds or vagcom
setup right now:
- tps sensor
- 2x knock sensor (one for cylinder 1,2,3 and one for cylinder 4,5)
- Ignision Distibutor with hallsensor
- 2x vr sensor at the flywheel (1x VR crankhome 1 teeth and 1x VR 135 crankteeth)
- 3-pin pwm idle control valve
- MAF
- 5x Bosch 315cc injection valves
- narrow band o2-sensor
the main problem is, that the idle is pretty shitty and you have to tune the engines idle rpm and AF-ratio with the engine running in diagnostic mode and some sort of o2-test equipment. On top of this in many times the engine dies in diagnostic mode. that whole thing is quite a pain in the ass.
so i want to bring it to some sort of this in the future:
- rusefi ecu
- tps sensor
- 2x knock sensor
- map sensor
- intake air temperature sensor
- baro correction (i read its not yet supported atm?!)
- crank sensor (60/2 if required)
- camsensor
- electrical gaspedal (i have a audi a4 b5 gaspedal laying around)
- electrical throttle body (i don't know which one yet)
- wide band o2-sensor
and i think the injectors can stay. they should be good for now.

Re: Audi Coupe Quattro 20V (7A)
the wide band sensor would require a wideband controller since rusEfi wbo controller would not happen until somebody implements it one day. We have hardware progress and now I am totally not having time to even solver the 2nd revision of the board.Horsty wrote:- electrical gaspedal (i have a audi a4 b5 gaspedal laying around)

ETB. Why do you need/want it? If you are a software developer it could be a cool thing to play with, but as of today we pretty much do not have ETB here. Again, would not happen until somebody develops it

Re: Audi Coupe Quattro 20V (7A)
etb is actually just a nice to have and not really needed.
it would make the whole cruise control thing theoretically a little bit easier i guess.
oohh... i have propably overlooked that there is no wbo controller yet... damn, my fault.

Do not reinvent the wheel!
you need to set everything as 2.2T AAN engine.
and Turbo too
I have 2.2T (ADU) for a long time.
built 7A engine turbine.
If you do not push the boost greater than 1 bar all will work in the stock motor
