And again, it costs 3 times as much, with 2 of those credits being "throw away", since you are licensing [someone else's VIN + new strategy] combination. That doesn't seem fair.
I still don't understand why they can't just license your VIN, once. Then the vehicle writer can just look for the VIN of the ECU you are writing to for validation, and ignore the VIN on the tune file because it is irrelevant.
