long story, 6.7 Cummins. programmed with Auto Cal. driving and truck just shut off. lost communication with ECM. was able to program it again not realizing it was a different VIN than the ECM originally. trying to reload the tunes back in and getting a $053E VIN Security Restriction, .ctz file does not match controller vin.


is there a way to overwrite this and get the correct vin back in to the ecm so i can reload the tunes?
