    Unable to write to PCM, System ID's are dfferent?

    Hoping someone can help shed some light on this issue...

    I'm having trouble writing a tune to my unlocked PCM.

    The PCM is from Livernois Motorsports.

    The PCM originally replaced my 2016 Challenger Hellcat's stock PCM, but I now want to add it to my 2018 Charger Hellcat, but when I attempt to write my tune, I get a message back stating "unable to write, system ID's are different".

    Is there a quick fix for this?

    I have licenses for both vehicles (PCM & TCM).

    Original tuning completed with same MPVI2, as well as, same tuner.

    Thank you for your time,

    Dakota

    i had a recall on a f150 updated pcm. it wiped the hp tune off i wasn't able to reinstall the hp tune hpTuners made me purchase credits again stating the recall re-calibration changed the pcm id. I was't happy about that but it wasn't my money.

    Hmm interesting... Mike@OSTDyno was able to change the vin and recalibrate the pcm to my 2018 Hellcat, but wasn?t able to overwrite the EPROM... Not sure why, but he has to send it off to have the portion done...
