What up guys, does anyone here have a JB4 software tune? I'm looking to try something related to my diagnostic app (completely harmless, of course) on one of those cars. However, it has to be a car that uses K-line and not CAN, i.e. up to 03/2007 as a build date in most cases. Anyone got one? Again, I guarantee nothing bad will happen to your car, I just want to test some diagnostic communication. Thanks very much in advance!
