I bricked my 99 Trans Am PCM last night, trying to full flash with just a jumper box on the battery.. damn thing locked up right after the flash and won't respond worth a damn.. It runs, but it can't be reflashed. Can I get any 99-07 LS1 style PCM and flash my COS5 into it? I was thinking about buying one of the ones off eBay for $100 shipped.. that program the VIN into the pcm before they ship it. Do I need to buy a new license if I do that? Other option is going to junkyard and buying one out of a Blazer/S10 (my 03 blazer PCM is the same Delphi PCM, i'm pretty sure I can full flash it to the LS1 OS).. What do you guys do when you brick one?
