HP Tuners MPVI4 — All-In-One ECU Tuning & OBDII Scan Tool Interface

Product details

The HP Tuners MPVI4 is the next-generation, all-in-one interface for scanning, diagnosing, data logging, and custom tuning your vehicle. Whether you're dialing in a diesel workhorse, a daily driver, a late-model muscle car, or powersports, the MPVI4 connects to your OBDII port and unlocks the full power of HP Tuners' VCM Suite — the industry standard in DIY and pro-level ECU tuning. If you've been weighing MPVI3 vs MPVI4 , the MPVI4 is the clear upgrade: a faster dual-core processor, Wi-Fi connectivity, expanded onboard memory for standalone data logging, and an improved OBDII connector for rock-solid connections. Why the MPVI4 Belongs in Your Toolbox One device, three jobs — scan, diagnose, and tune. The MPVI4 doubles as a powerful OBD2 scan tool and a full ECU tuner. Wireless freedom — built-in Bluetooth 5.2 and Wi-Fi (802.11 a/b/g/n) for faster data transfer and cable-free logging. High-speed standalone data logging — expanded bandwidth and memory capture more channels at higher resolution, even disconnected from your laptop. Massive vehicle coverage — compatible with thousands of years, makes, and models, from diesel trucks to gas muscle and powersports. Stronger OBDII fitment — a redesigned tapered connector grips the port tighter for a more reliable link. PRO Feature Set included — works with PROLINK+ and ships ready for advanced tuning workflows.
