    Controller Unlocker Web Service Exception

    I get this error "Controller Unlocker Web Service Exception " is there something wrong with the HPT server today? I am trying to read a 2017 Corvette and naturally the customer is from out of town and waiting!

    Are you using 4.0 or 4.1 software?

    I am using 3.6.26 I have tuned several 2017 Corvettes without issues other than getting into your server. I am also using the old MPVI 1 box not your new interfaced.

    Update to 4.0.12, 3.6 is no longer supported.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    "2Note: 2017+ GM 8-Speed and 10-Speed Tranmission Control Modules require unlock via HP tuners GM TCM Unlock service before tuning."

    If its the 8-10spd TCM, you have to send it out for modification as far as i know
