HP Tuners credits

The licensing currency HP Tuners charges to unlock a specific vehicle (VIN) for tuning on your interface.

Credits are HP Tuners' pay-per-vehicle licensing system. To write a tune to a vehicle you must first license its VIN, which consumes credits stored on your MPVI interface; reading a stock file and logging are generally free, but writing a modified calibration requires the VIN to be licensed. The credit cost varies by vehicle and is typically higher the first time a given VIN is licensed, with reduced or no additional cost to re-tune the same VIN later on the same interface. Plan credits before you start so you are not stranded mid-project. You purchase credits through your HP Tuners account and they load onto the interface. In the software, your credit balance and licensed-VIN status appear in VCM Editor under the Help/About or Credits/Interface info dialog, and you'll be prompted to license a VIN the first time you attempt to write to a new vehicle.
