HP Tuners Announces MPVI4 — The Next Evolution in Vehicle Tuning

BUFFALO GROVE, IL — October 28, 2025 — HP Tuners, the leader in automotive calibration and diagnostic solutions, is proud to announce the release of MPVI4, the latest generation of its flagship OBDII interface. Designed for professionals and enthusiasts alike, MPVI4 delivers faster performance, cleaner data, and an even more refined user experience.

Built on a foundation of innovation and precision, MPVI4 represents HP Tuners’ ongoing commitment to improving the customer experience through cutting-edge technology.

Smarter, Faster, Stronger

Equipped with a dual-core 1.7GHz processor and 1GB of RAM, MPVI4 offers over 30 times more memory than previous generations, enabling faster reads, writes, and logging speeds. This expanded capability brings scanning performance on par with VCM Scanner, delivering professional-grade data accuracy in every use case.

A new tapered OBDII design ensures a stronger, more secure connection for both shop and mobile environments, minimizing dropped communications during tuning or diagnostics.

Built to Evolve

MPVI4 connects seamlessly with VCM Suite 5.2, HP Tuners’ complete tuning and diagnostic software package that includes VCM Editor and VCM Scanner. Users can read, edit, write, and log with greater efficiency than ever before — whether they’re tuning on the dyno, scanning at the track, or troubleshooting in the field.

Every MPVI4 comes standard with Pro Feature Set, providing compatibility with PROLINK+ for analog and CAN-based data inputs, as well as standalone data logging functionality for professional-grade analysis.

Ready for Every Vehicle

From daily drivers to dedicated race builds, MPVI4 supports thousands of vehicles from over 40 manufacturers, including performance cars, trucks, SUVs, and powersports platforms. Designed for flexibility, it gives tuners and enthusiasts a single device that works across their entire garage.

Upgrade Program Coming Soon

To ensure existing customers can take advantage of the latest hardware, HP Tuners will soon offer an interface upgrade program for all previous generations, allowing MPVI, MPVI2, MPVI2+, and MPVI3 owners to upgrade to MPVI4 at a discounted rate.
