HP Tuners' newest and most advanced vehicle interface — designed for custom calibration, diagnostics, and data acquisition across thousands of makes and models. The MPVI4 is your all-in-one solution for scanning, diagnosing, and customizing your vehicle whether you are troubleshooting a problem, improving fuel economy, or chasing better performance. Faster logging. Stronger connection. Smarter architecture.

Key features: Dual-core 1.7GHz processor with 1GB RAM delivering over 30x more memory than the MPVI3. Bluetooth 5.2 for wireless connectivity. Wi-Fi 802.11 a/b/g/n up to 150Mbps (available with a future firmware update) for dramatically improved wireless transfer speeds. High-speed standalone data logging with expanded bandwidth comparable to a wired VCM Scanner experience. New tapered OBDII connector for a stronger, more secure connection. Three multicolor RGB indicator lights. Comes standard with the Pro Feature Set. Compatible with PROLINK+ straight out of the box.

Works with VCM Suite 5.2 and higher. Compatible with hundreds of supported controllers and thousands of makes and models — late-model muscle cars, daily drivers, trucks, and powersports vehicles. One device for everything in your garage.

Credits are required to license controllers and vary by make and model — credits are sold separately. Select your credit bundle at checkout to get started immediately.

In the box: MPVI4 Interface, USB-C cable, Quick Start Guide.

Important — models not currently supported on MPVI4: 2003–2007 Ram 5.9L Diesel, most 1995–2004 Dodge/Ram/Jeep/Mercury models with legacy NGC1 and JTEC controllers, and select other legacy applications. If you are purchasing this for a 2003–2007 5.9 Cummins, this device is not yet supported — see our HPTuners MPVI3 or EFILive FlashScan V3 options instead. Full unsupported model list available on the HP Tuners website.
