    Default 2000 truck with locked PCM, buying new PCM

    the PCM on my truck is locked through nelson performance. im going to try and sell the PCM to someone and buy a new PCM. if my memory serves me right i remember seeing a 03 v8 truck at my local junk yard. can i take that PCM and run my 2000 truck with it?

    No, you can only use a PCM from a 99-02. 03+ uses a 1 meg flash chip. 99-02 are only 512k.

    Weve dealt with a couple locked Nelson PCM's, if you contact Nelson he will send you a stock PCM at no charge with the catch that you send him back the locked one.

    You might get caught out there too.
    If VATS are turned off then you will be able to swap it in to another vehicle, if the VATS are still enabled then because the PCM is locked you won't be able to perform a VATS relink either!.
    Contact wait4me on this forum, he could unlock the PCM for you if Nelson won't do it.
