Hi guys,
I'm working at the moment at a friends AC Cobra with a '95 LT1 and PCM. The wiring harness is custom from PSI conversion, F-body based. As already said, EEhack won't connect but TunerPro does. Another strange thing I discovered, the data line just goes to pin D30, not pin D29. In the wiring diagrams both pins should be used together for the data stream. I added another pin but with no different result.
I used the same laptop with the same configuration as in my '95 Corvette, so it should have been plug and play.
BTW we used his ALDL cable that doesn't have a 12V supply, my cable has a power supply. I don't use an USB converter, as my laptop has a comport.
Any ideas whats the reason for this? Maybe too high resistance for the ground? Bad cable?
Thanks and best regards,
Max
