JensIf you read this, I figured out why your tech said you do not need the 7's wire, he is thinking of a pre 84 model with beeing unaware the 84 and up have knock control units. Gosh this brings up other issues such as, I'm sure you do not have the 2-plug actav. for the transi on the motronic, which also confuses the Engine side verses the transi side interchannging of readings mmmmmmmmm Sincerely Jens
ikerrThanks, not sure I understand what to do about the transmission plug. Car is running alright, but not to fast. Need to install a vacuum/boost guage to see what is going on. Of course, you know there is no longer any 3500 rpm full throttle cut off. I'll know about my mileage soon, which may help provide a clue, except that I'm driving faster now :-) Thanks for all your, and everyone's, help. Step by step! - Ian '85 745i '72 2002
