    MPV2 stopped working on JTEC ECU

    Hi
    I'm having problems writing JTEC ECUs with my MPV2. When I try to write it shows ?Baud Rate: Timed Out?. I?ve tested 3 different jeeps and the problem was the same. I?m only having this problem with these type of ecu.

    Thanks.

    Support ticket opened. Today I tested with another jtec and the error was "Controller Init: Failed". VCM Scanners works wasn't able to tune the vehicle
