    2020 Corvette, can I send in PCM from other Corvette to unlck/tune?

    Doesnt look like they offer buying a new pcm outright and unlocking it for you so you can swap it and start tuning. Can i send in a stock PCM from another 2020 (or can it be from a 2021, 22 23?) and have it unlocked and right VIN etc put in it? You cant pull the factory tune out of the car as it sits to email to them like we would normally do on unlocking older PCMs using a pcm from another car

    No. These E99 ecms don't like being swapped around.

    Basically the only way is you send us your ecm
    You do NOT install a different ecm into your vehicle in the meantime
    We then unlock your ecm and send it back to you

    from there is pretty much turn key.

    So there is NO way to do a PCM swap out service for customers? No way to eliminate the downtime of pulling car apart, having on a lift for a week to wait for HPT to turn PCM around???

    I know once there was an unlocked on put in you cant stick another one in for the meantime
