as you ppl know, there is 3 diferent ecus for the valver.
S 101 261 102 - C575 - F7P 720
S 101 262 105 - C57D - F7P 722
S 101 262 102 - C57D - F7P 722
The F7P 720 doesnt have cat or lambda sensor (no 5º inj cold start either). My question is if anyone knows if this engines ecu (S 101 261 102 - C575) would run on a F7P 722 with a proper eprom?
Willy has got only one ecu (I think). Can you change valver to willy and the other way only by using other eprom?
