    Unfortunately the Vortec PCM's are not supported. Your best bet is to do the 0411 PCM swap with help from Lextech's repinning spreadsheet (send him a PM for info). It's not all that difficult to do and the PCM is much better than the 96-00 Vortec...

    Sorry malibu795 they aren't the same ECM's, the 96-97 had one type, then it changed again for 98-00 (the one we supported but have since retired active work on).
    I no longer monitor the forum, please either post your question or create a support ticket.
