Griffin Motorsports - Stage.I Remote Tuning Package featuring the HP Tuners MPVI4 Interface - Professional Vehicle Tuning & Data Logging.
Modern engines are incredibly capable—but only when the calibration matches the hardware. Ported Blowers, E85, Upgraded Fuel Injectors, Head & Cam Packages and cooling mods all demand precise control over spark, fueling, torque management, and safety strategies. Guesswork doesn’t cut it anymore.
The HP Tuners MPVI4 is the industry-standard vehicle interface that unlocks full access to your ECU and TCM, allowing you to flash custom calibrations, log high-resolution data, and safely optimize your LS/LT/Global B platform—whether you’re tuning the car yourself or working with a professional remote tuner.
This is the same tool used by OEM calibration engineers, professional race teams, and top tuners worldwide.
What the MPVI4 Is
The MPVI4 is a high-speed vehicle interface (VCI) that connects your car to HP Tuners VCM Suite, giving you:
Full ECU and TCM read/write capability
High-speed data logging with expanded channel access
Support for custom tuning files created by you or your tuner
Compatibility with gasoline, E85, flex-fuel, boosted, and NA LT setups
If you’re modifying your engine, this isn’t optional—it’s foundational.
Designed for Remote Tuning
If you’re working with a professional tuner, MPVI4 is the required communication bridge:
Read and flash tune files your tuner sends you
Log high-resolution data exactly how they request
Email logs and revisions back and forth with confidence
Make changes on your schedule—no shop visits required
Most top LT tuners require HP Tuners for remote support because of its reliability, data depth, and consistency across platforms.
Why MPVI4 Is a Major Upgrade Over Previous Generations
Compared to earlier MPVI interfaces, the MPVI4 delivers:
Faster processing and improved stability
Expanded logging bandwidth for modern ECUs
Improved USB-C connectivity
More efficient handling of complex LT torque models and flex-fuel data
Support for the latest GM operating systems
When you’re logging ethanol content, fuel pressure, airflow models, and torque intervention all at once, speed and reliability matter.
Platform Capabilities (What You Can Control)
With MPVI4 and VCM Suite on an LT engine, you can tune and log:
This level of access is why HP Tuners remains the gold standard for GM performance tuning.
Perfect Pairing with GMS E85 & Fueling System Upgrades
When combined with Griffin Motorsports E85 and fueling solutions, the MPVI4 becomes even more powerful:
Works seamlessly with Advanced Fuel Dynamics E-Sense ethanol sensors
Allows tuners to leverage accurate ethanol content & fuel temp data
Essential for dialing in high-flow pumps, injectors, and PTFE fuel systems
Enables safe optimization of boost + E85 combinations on LT4 platforms
In short: the hardware gives you capability—the MPVI4 lets you use it safely.
