Remote calibration for the C8 Corvette E-Ray, covering the LT2 V8 and its hybrid front axle.
Fuel options
Single fuel is pump gas only. Dual fuel and flex fuel cover E85 and blends.
Before you order
Contact Johnson Tuning to confirm your hardware, fuel system and tuning platform.
HP Tuners requirements
For a supported 2024–2026 E-Ray, budget 8 Universal Credits for the E99 engine controller. The original ECM must complete HP Tuners’ E99 Global B upgrade before engine tuning. Confirm your VIN, model year, controller and service eligibility with Johnson Tuning first; the upgrade page currently names 2024–2025 E-Ray applications.
If transmission tuning is included, the original T46 TCM also needs its separate upgrade and 6 additional credits (14 total for ECM + TCM). MPVI4 and current VCM Suite are required for T46 tuning. An ECM-only order does not include TCM calibration.
Shop MPVI4 and available credit bundles. The store offers 0, 2 or 4 credits with the interface; contact Johnson Tuning to arrange any remaining credits. Hardware, credits and controller upgrade services are separate from the remote tune. Confirm the final requirement against HP Tuners’ supported vehicle list before ordering.
