Tuning tools for enthusiasts and workshops

HP Tuners is an American company developing tools to read and modify a vehicle’s engine and transmission control. The tools are used by professional tuners and workshops, but also by enthusiasts who want to understand their car better and adjust it after new parts such as an intake, exhaust, camshaft or forced induction. The coverage includes a wide range of vehicles, mainly from GM, Ford and the Stellantis brands Dodge, Ram, Jeep and Chrysler, with new models added over time.

HP Tuners’ key products

VCM Suite consists of VCM Editor, where you read and edit the calibration, and VCM Scanner, where you log data and read fault codes in real time. The connection to the vehicle is made through an MPVI interface that plugs into the diagnostic port. To write a new calibration to a vehicle you use credits, which license that specific vehicle. For data acquisition there are also extra modules and accessories, for example for wideband lambda measurement. See each product for what is included.

Frequently asked questions

What are HP Tuners credits?

Credits are used to license a vehicle so you can write a modified calibration to it. The number of credits depends on the vehicle and which control units are being tuned. Scanning and data logging normally do not require credits.

Can I save the original calibration?

Yes, it is good practice to always read and save the vehicle’s original file before changing anything. That way you can return to the starting point if needed.
