Credits 101

What Are Credits?

Credits are the currency used by HP Tuners to purchase licenses for tuning specific vehicles. A license is tied to three key pieces of information:

1. VIN (Vehicle Identification Number)
2. Serial Number of the controller
3. Operating System (OS) on the controller

Once a vehicle is licensed, your HP Tuners interface device can write modified tune files back to that specific vehicle. Unlicensed vehicles cannot be tuned.

Key points:

• Most vehicles require between 2 and 6 credits to license.
• Universal Credits can be used for any supported vehicle, regardless of year, make, or model.
• Older MPVI units (e.g., MPVI) used brand-specific credits (e.g., GM, Ford, Dodge). These credits are still valid if unused.

Recovering Credits

HP Tuners does not allow the transfer of credits from one interface to another due to security concerns. However, there are exceptions:

• Upgrading Your Device: If you are exchanging your old device for a new one, credits from the old device can be transferred.
• Lost or Stolen Devices: In some cases, credits may be recoverable.

For assistance with recovering credits, please contact HP Tuners Support.
