Trying to help out a friend with his supercharged Corvette. He purchased his HPT interface used with 4 credits. He is unable to license his vehicle to the interface. When he tries, the only option he gets is to continue without licensing. the vehicle. he does have a 2 bar custom OS on the car. One weird thing I noticed is that the VIN in his PCM does not match the physical vin on his car. another weird thing I noticed is that it says YYYYYYYYYYYY for the VCM ID. He did mention something about having to swap PCM's before. Any help would be appreciated.
