Upload your personal repository to Google Drive or Dropbox. If your laptop dies at the racetrack, you lose nothing.

Professional tuners spend hours—sometimes weeks—dialing in a custom remote or dyno tune for a client. That file is their intellectual property. However, many unscrupulous users will pay for a remote tune, read the file with their MPVI (which they own), and then upload it to the Repository.

Now, anyone with credits can download that professional’s $500 custom tune for the cost of a single credit (~$50). This is effectively piracy.

First, let's clarify the terminology. HP Tuners itself does not officially operate a "one-stop shop" cloud repository like some competitors (e.g., Cobb Tuning’s Accessport Manager). However, the community has built robust repositories across various platforms.

An HP Tuners tune repository is a collection of .hpt files (the native file format for HP Tuners VCM Suite) shared by users. These files contain every parameter of a vehicle’s ECU and TCM (Transmission Control Module), including:

These repositories live on forums, social media groups, and dedicated file-hosting websites. The most famous of these is the HP Tuners Repository section on the official HP Tuners forum, as well as massive communities on Facebook (e.g., "HP Tuners Tuning Help") and Gearhead-EFI.
