Introducing HP Tuners’ newest and most advanced vehicle interface. Designed for custom calibration, diagnostics, and data acquisition, MPVI4 sets the foundation for what’s next.

MPVI4 is your all-in-one solution for scanning, diagnosing, and customizing your vehicle—whether you’re troubleshooting a problem, improving fuel economy, or chasing better performance. Faster logging. Stronger connection. Smarter architecture. MPVI4 is ready when you are.

Includes 8 credits. HP Tuners uses a credit-based licensing system. 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. For some models additional credits may be required for TCM, FICM, FSCM, and CCM tuning (sold separately).

Please be aware that this is a powerful programming tool. It will unlock the onboard ECU on the vehicle being tuned to the point where an inexperienced tuner may inflict engine damage accidentally. There are no built-in safeties. Please see applications tab for vehicle credits and specific notes that may pertain to your vehicle.
