How do HP Tuners credits work when licensing a vehicle for tuning?
- Credits buy licenses. They're HP Tuners' currency; you spend them to license a vehicle's controller so the interface can write to it.
- A license is tied to three things: the VIN, the controller's serial number and its operating system. As long as those stay the same, you can reflash that vehicle as many times as you like at no extra cost.
- Cost per vehicle: typically 2–6 credits (HP Academy); many engine computers take 2 (HP Tuners). Transmission and other controllers are licensed separately.
- Universal credits: MPVI2 and newer interfaces use universal credits for any supported vehicle; the original MPVI used brand-specific credits.
- Capacity: one interface can hold thousands of vehicle licenses.
