HP Credits

These are HPTuners Universal Credits only. If you are looking for a device you can find the MPVI2 here.

HPTuners uses a credit-based licensing system. Universal Credits are used as currency to purchase licenses for the different modules in a vehicle.
Licensing a module gives you the ability to tune it. The number of credits necessary to purchase a license varies depending on the vehicle.
Many vehicles are 2 credits for licensing the ECM/PCM, and may have additional options such as a TCM, FICM, or CCM.

Vehicle licenses are tied to the VIN, PCM OS, and PCM Serial Number. If those values don’t change, the vehicle will remain licensed on that
interface and can be tuned indefinitely.

A list of supported vehicles and credits required can be found here.
