Grasping at straws here, as I think I know the answer, but maybe someone here has had this run of bad luck and has a quick fix. When attempting to load a different tune into the car using the MVI2 device and TDN, the tune write was interrupted somehow. The unit had been loading and swapping tunes fine for days and then that event occurred. Now after the interruption or error, whatever occurred, the unit is now a brick. "Controller INIT: Failed", is the error when attempting to load the tune files. I have tried to connect to the unit with Polaris digital wrench to verify that the ECM was good or communicating, but that failed as well now too, "No Response from ECU". Unit will not even attempt to crank, dash lights are lit up like a Christmas tree. Anyone else? Thank in advance!
