I tried all that, so I pulled this pcm out and have it on my desk right now. wiring is hooked up as follows Black plug, 30 and 31 12v, Blue plug , 3 12v, 1 ground, 30 serial data. Still doing the same B.S. chances are they did something stupid and bricked the pcm before I tried to read Calibration. Just gotta do a little more digging, if there is some difference ill figure that out. So the 03 P59 i have was a brick and i fixed that after i cloned it, saved the file on my desktop one night when I was drunk with Hammer. Cloned it and fixed the old one. Don't know about the lt1 or 94 v6 this is my second one. First one runs and i drive it and been tuning it.
