The VF Engineering Hex Tune delivers more than just power -It’s engineered to provide consistent and reliable performance
on the street or at the track in a way that inspires confidence ever time you press the pedal. The HEX Tuning software upgrade for the S55 3.0L
turbocharged engine found in the F8X M3 & M4 is a proper ECU recalibration that works in conjunction with the ECU’s self diagnostic and safety features, including but not limited to, advanced OEM knock detection. This approach not only allows for more consistent and reliable power than “piggyback” tunes, it also ensures that the ECU functions as originally intended while providing noticeably increased horsepower and torque
delivery even with different fuel qualities, under a wide range of driving conditions, and in various climates around the world.
HEX Tuning software by VF engineering is expertly calibrated over many months of testing, both on the road for real world results, and in-house on our Mustang AWD and DynoJet 2WD chassis dynamometers. Each Stage power level is engineered to provide increased horsepower and torque across the entire rev range by optimizing ignition timing, boost pressures, cam timing and vanos settings, throttle maps, and many other calibration tables in within the ECU to function in absolute synchronicity.
