Purchasing used ppm for customer, new and aftermarket on national back order. All used parts suppliers warn that a used gm pcm may not be programable. Is it possible ? Are there any work arounds?
There is a few programmers that can clone your original ecm to the used one. Best one for GM I use is I/O Terminal. It also does GM Body and Steering Racks, Ford BCM.. I also have used Flex for Gm Ecms
