Inliners International Forums General Discussion Hi Performance Help needed to change 4 piles into 1

I spent yesterday on the MS project. I found a problem that I think is in the GM adapter board. When using the stock ECM the test truck starts and runs as it should. When the MS is plugged It does not communicate with the laptop. When I remove the GM adapter board and plug in the Stim board it connects to the laptop and seems to work fine. I plugged in the GM adapter board in the truck without the MS and checked to see if I was getting 12v where I thought it should be, DB37 pin #26. I wasn't, but I was getting 12v on several pins where I don't think I should, pin #s 20, 22, 23, 24,25, & 29. I will need to check out GM plug to see if I have some extra solder on the GM plug that I didn't remove when I pulled it from the donor ECM. It won't get done before the demo at the convention. Beater
