    Ed Wright locked PCM

    Will your tuner work with my locked Ed Wright PCM ?
    If not, is there someone I can send it to, to unlock it besides Ed Wright.

    Thanks,

    You can generally overwrite the existing tune but he messes with the checksums and most tuning software will not touch it as it is too risky. The checksums are your only method to ensure you are dealing with a valid bin file. (Especially with the 8 Segment 99+ bins)

    Are you wanting to edit his tune? Otherwise you should be able to overwrite it with a stock tune or one that you have modified with no issues.

    Somebody should bitch-slap all who lock tune files.
    Publicly posting a good method to read and check
    them would be The Hand.

    But, the repository might already hold something
    for you that's as good or better than a mail-order
    best-guess.

    Cool...

    Don't need the Ed Wright tune.
    I'll just write over it.

    So this is a 100% certain deal with an Ed Wright 1998
    locked PCM.
    I can just write over Ed's 'tune' with HP Tuner ?
    I know 'edit' can't do it.

    Thanks,

    Only thing is, with '98s you need to be very careful
    about where you pick up that stock tune from, there
    are several different OS variants that are incompatible.
    There are warnings about this, I've seen but never
    bothered with the practical details. But you should
    be able to get one that works; just "safe sex"....
