C8 Corvette LT2 6.2 Flex Fuel Tune

Compatible with 2020–2026 Chevrolet Corvette Stingray & 2024–2026 E-Ray (LT2 6.2L)

Take full advantage of both pump gas and E85 with a custom Flex Fuel Tune for your LT2-powered C8 Corvette. Professionally calibrated using HP Tuners software, this tune automatically adjusts engine parameters based on the ethanol content detected by your vehicle, delivering optimized performance whether you're running premium pump fuel, E85, or any blend in between.

Designed for modified LT2-powered Corvettes, this calibration is ideal for vehicles equipped with common bolt-on upgrades such as aftermarket intakes, headers, exhaust systems, and intake manifolds. With a properly installed DSX Flex Fuel Kit, your Corvette can seamlessly transition between fuel types without requiring separate tunes.

Each calibration is tailored to your vehicle and includes adjustments to ignition timing, fuel mapping, throttle response, torque management, and other key engine parameters for maximum performance and drivability.
