Generic MPVI4 OBDII Diagnostic Interface — USB-C OBD2 Scanner, Fast Dual-Core Logging (1GB RAM)

The MPVI4 updates HP Tuners' OBDII interface line with a faster processor, more memory, and a redesigned cable fit for everyday garage use. It pairs with the free VCM Suite software to read trouble codes, capture high-speed data streams, and connect with a wide range of vehicle control modules. Built for enthusiasts and professional shops, this interface brings standalone data logging and improved wireless capability (via future firmware) to diagnostics and tuning tasks.

How does the MPVI4 improve data logging and diagnostics?

The MPVI4 is engineered for cleaner, faster logging thanks to a dual-core 1.7GHz processor and 1GB of RAM, giving you smoother data capture and quicker on-device processing. That hardware boost reduces dropped parameters and supports higher bandwidth logging comparable to wired setups.

• High-speed standalone data logging for more parameters at greater sample rates
• Processor and memory upgrades reduce latency and improve log clarity
• Improved tapered OBDII fitment for a secure, stable connection

Which vehicles and systems can MPVI4 communicate with?

MPVI4 supports thousands of vehicles across 40+ manufacturers including cars, trucks, and powersports platforms. It communicates with multiple control modules to read DTCs, view live data, and interact with ECMs and TCMs where supported.

• Compatibility spans many late-model cars, daily drivers, trucks, and powersports units
• Works with VCM Suite to access engine and transmission modules and more
• Note: some ECUs require separate credits for full licensing (credits not included)

What does the MPVI4 include and what additional items are required?

The package ships with the MPVI4 interface and a USB-C cable and includes 0 credits for licensing vehicle controllers. VCM Suite software is downloadable free, but some operations or specific controllers require purchase of credits or additional hardware such as PROLINK+.

• Includes MPVI4 OBDII interface and USB-C cable
• Free VCM Suite 5.2+ software download required for operation
• 0 credits included—additional credits sold separately for controller licensing

How will wireless and pro features affect my workflow?

MPVI4 is built with improved Wi‑Fi transfer speeds planned for a future firmware update, which will speed up file transfers and remote workflows. Pro features like standalone logging and PROLINK+ compatibility let shops and tuners capture detailed sessions without tethering to a laptop.

• Future firmware will enable faster wireless transfers for quicker workflows
• Standalone logging reduces dependence on constant laptop connection
• Pro feature set integrates with professional accessories for advanced tuning

Who this is for: The HPT MPVI4 suits performance enthusiasts, DIY tuners, and professional shops that need reliable, high-bandwidth data capture and broad module access. If you require fast logging, secure OBDII fitment, and a device designed to grow with firmware and accessory upgrades, MPVI4 is built to fit those needs. Note that while the interface and software facilitate diagnostics and tuning, specific ECU operations may need purchased credits or supplementary hardware.
