2020–2022 3.0L LM2 Duramax Calibration

Custom 2020–2022 calibration service from Automotive Innovations. Calibration is developed for the specific vehicle, engine, control module, and hardware configuration.

Available package options include standard multi-tune calibration and shift-on-the-fly (SOTF), with either four-week or lifetime support. Transmission calibration availability depends on the vehicle and controller combination; confirm compatibility before ordering.

Automotive Innovations brings 18 years of calibration experience and in-house Dynojet 224XLC calibration development. This is a custom calibration service, not an instant download. After purchase, provide your VIN, vehicle details, ECM/TCM information, stock file where applicable, and modifications.

For off-road/competition use only where permitted by applicable law. All emissions-related work must comply with applicable federal and state laws.
