What was your ECU situation again? No Check engine light with igntion to "ON"? Do you have power to the red fuse holder above the ECU? There are situations where the ignition driver chip dies (and there are NO replacements)
Motronic ECUs can be bench tested (to some degree) but not by amateurs. I know of 2 people in the world that do this regularly in the aftermarket. One is in Estonia and one is in Denver. The Denver guy is Steve Eiche however, Steve recently got ripped off by montanarally (on this forum) after Steve fixed montanarally's ECU and montanarally failed to complete payment after Steve shipped the ECU. Steve is rethinking helping us in the future (way to go montanarally).
