Hi,
is there a way to run this kind of ecu on the bench and check channel 91 for immo status like on the later M3.83?
I had a look at the wiring but there is no direct K-Line to the ecu. Only to the dash and immo box...
D6, D9, D10 - +12V
D11, D12, E11, E12 - ground
A7 -W wire.
Thats all i found but W-line is to the immo box.
maybe someone can help with this old stuff
