What Is MPVI4?

Performance and Precision

Every generation of HP Tuners’ hardware has pushed the limits of what’s possible — and MPVI4 is no exception.

• Dual-core 1.7GHz processor with 1GB RAM — over 30x more memory than MPVI3.
• Standalone data logging performance on par with VCM Scanner, providing the same level of speed, clarity, and accuracy trusted by professionals.
• Refined tapered OBDII design for a stronger, more reliable connection every time.

These improvements mean less waiting, cleaner data, and a faster, more responsive tuning experience across every supported platform.

Scan. Diagnose. Tune.

At its core, MPVI4 is designed to make custom tuning straightforward and repeatable — whether you’re in your garage or on the dyno.

Using VCM Suite, your tuning process follows four simple steps:

1. Read your vehicle’s stock calibration with VCM Editor.
2. Edit key parameters like fueling, ignition, or transmission tables.
3. Write the updated calibration back to your vehicle using MPVI4.
4. Log performance data with VCM Scanner to verify your results.

Each step is faster and smoother than ever, with cleaner data and precise control that lets you focus on results instead of setup. With enhanced scanning performance matching the precision of VCM Scanner, MPVI4 makes data capture and analysis more efficient than ever — whether you’re troubleshooting, logging on the dyno, or refining your tune on the road.

Compatible with More Than Ever

MPVI4 expands HP Tuners’ already extensive platform coverage, offering support for thousands of vehicles from 40+ manufacturers.

From high-performance sports cars and daily drivers to trucks and powersports, MPVI4 gives you one tool for your entire lineup. It’s fully compatible with PROLINK+, allowing users to integrate analog and CAN data inputs for enhanced monitoring and diagnostics.

No matter what you drive, or how many vehicles you tune, MPVI4 keeps you connected.

Built for the Future

Underneath its refined design, MPVI4 is built on a modern architecture designed to grow with you.

With Bluetooth 5.2 connectivity and built-in hardware for future Wi-Fi integration, MPVI4 is ready for new features, firmware updates, and expanded support as HP Tuners continues to innovate.

Whether you’re scanning data at the track, tuning at the dyno, or logging performance off-road, MPVI4 is ready for wherever your tuning journey takes you.
