I went to trouble shoot a 2008 LS3 Pro charged corvette engine swap that they couldnt get running. The E38 pcm wasnt doing anything except pulsing the fuel pump like crazy, car wouldnt run. I was able to download the mail order tune that came with the pro charger kit and to my surprise found a 2006 LS2 tune in the 2008 E38 PCM. How is that even possible, is that what fried the pcm? The car did start a few times with this pcm but never ran but a few seconds then it quit starting all together.
