Aloha,

BMW 87 325iC m20b25 n/a ITB's

Is there a chart showing test procedure and results values at 55 pin connector for MS/2 ?

Like the one on Bentleys' manual for oem ? like this one...

Where and how to access ECU: I have tried to illustrate where and how to access the ECU, it is in the glove box compartment. To access it open your glove box and undo the two screws holding the plastic cover that is at the "ceiling" of the glove box compartment, under there you will

Trying to double check all results at connector since ICV is not buzzing, 1-3-5 injectors not firing, Autotune function always leans out maps, etc.

Mahalo,
Frank

I don't think so because you can wire it any number of ways.
