The locked factory ECU era is over. Replace the factory ECU with the Acclivity Axiom stand-alone controller and FastUTV calibration for your 2021+ Can-Am Maverick X3 with Bosch MG1 ECU. No factory ECU unlocking is needed. Plug-and-play hardware connects at the factory ECU location; the selected tuning and supporting hardware must match your vehicle.

Other fuels and upgraded configurations require vehicle-specific calibration review. No Turbo RR power target is implied for a non-intercooled vehicle.
Performance and Installation
Wheel-horsepower figures are FastUTV tuning targets for the stated vehicle, fuel and hardware configuration, not guaranteed results. Actual output varies with vehicle condition, modifications, fuel quality, environment and dyno method. Provide the exact model, trim and modifications before calibration. Install all supplied supporting hardware before using its tune; do not use an ethanol or upgraded-injector calibration on unmatched hardware.
Flex-fuel and custom big-turbo packages have no fixed horsepower claim. FastUTV matches the supplied fuel-system hardware and MAP sensor, where included, to the vehicle configuration.

Fitment and Setup
2021 and newer Can-Am Maverick X3 models equipped with the factory MG1 ECU. Confirm ECU connector, vehicle configuration, modifications and the required calibration with FastUTV before installation. Plug-and-play describes the hardware connection; a calibration appropriate to the engine and fuel is still required.
