    MPVI2+ Wont write gen2 viper

    Read the car fine, was even able to log. Try to write and it just says controller init timed out. after requesting access/downloading bootloader/executing utility routine. and now it wont even log, though I could read it again.

    on todays beta using an mpvi2+

    Make sure you disconnect the scanner from the vehicle (in the VCM scanner software) BEFORE attempting to write. You cant have the device connected to the scanner program AND write to the vehicle at the same time. Wont work.
