Remote calibration for the C8 Corvette Stingray and its LT2 V8.
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
Supported 2020–2026 Stingray E99 engine controllers require 8 Universal Credits and HP Tuners’ original-ECM Global B upgrade before engine tuning. Confirm the controller and upgrade service eligibility before ordering; the current E99 service page specifically lists Stingray applications through 2024.
If transmission tuning is included, the original T46 TCM also requires its separate Global B upgrade and 6 additional credits (14 total for ECM + TCM), MPVI4 and current VCM Suite. 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 your VIN, model year, controller/OS and transmission with Johnson Tuning and HP Tuners’ current supported vehicle list before ordering.
