    Locked Up MM3

    I wanted to adjust the values on my boost gauge on the unit and I don't know how I must have hit a wrong selection and now I have this.

    The unit is locked up and wont shut off.

    It won't acknowledge any button press.

    I don't think it is letting me put in the pic.

    Its stuck on Parameter config, number of warm-ups since DTC cleared.

    Its stuck on the selection to reset to default with the yes and no button on the side.

    If there is a way I can post a picture if needed please let me know.

    This is my daily driver and I drive at least 120 miles a day for work.

    X2- maybe longer than 30 seconds even- let all the power/memory drain out.
