ECM Problem of coarse
we have a 87 iroc 5.0 5speed, has cam, headers, 2chamber flowmaster.
i can short A B and get flash 12, all tests at aldl are good, test at ECM wires only found huge ground pull when keyon( also smells burnt), I can't access data with Modus scanner nor tech 1. The car pings like crazy and I need to get the data. My best guess is new ECM
p.s. The ground wires to the ECM connectors ohms good with keyoff

Re: ECM Problem of coarse
We just changed the ECM and now the MODIS can communicate, I checked all readings and now the car doesnt ping=)
Now all we need is a performance prom....Any help on where to locate one?
