Full calibration access for the Global B C8 Corvette (Stingray / Grand Sport / E-Ray / Z06 / ZR1). We unlock the factory control modules through the HP Tuners send-in service, then calibrate the ECM (and TCM, when included) to run as one.
Once unlocked: boost, cam timing, air/fuel, injector and ignition timing, rev limiters, torque management, and hundreds more parameters. What ships locked from the factory becomes a fully editable tune.
The unlock is a one-time send-in service. After that, all scanning, logging, and calibration runs through the OBDII port using an MPVI4 interface (MPVI4 not included in pricing)
What is included:
- Complete custom calibration (street & loaded dyno), NA or boosted by application
- ECM Global B unlock and licensing
- Overnight shipping to and from HP Tuners
- Required credits and neural network tokens
- 2 hours of dyno time (additional time billed at $175/hr)
Add TCM tuning (+$499): unlocks the T46 transmission control module for full ECM and TCM calibration, giving complete control over shift behavior alongside the engine tune.
