Plugged the PCM in about 30 minutes ago and powered it all up. PCM primed the fuel pump and is working. Did a read entire with HP tuners so I can pull out VATS and other unneeded things. VATS is like EWS in the BMW world.
I did have one issue with how the unloader relay works…when I turned the key to on (not crank) the engine started cranking. I used a start relay because that is how GM does it and the fuse/relay panel I got came wired that way. I will just have to run a wire direct to the starter solenoid the way BMW wants it. Easy fix….
