The locked factory ECU era is over. Replace the factory Bosch MG1 ECU in your 2021+ Can-Am Maverick X3 with the Acclivity Axiom stand-alone controller. Keep the factory connectors and mounting positions, without sending the factory ECU away to be unlocked.

The single-fuel packages each include the selected fuel calibration only, not all four tunes.

The Acclivity X3 expansion harness is available separately for $299. It supports adding flex-fuel, oil-pressure, fuel-pressure and coolant-pressure sensors, plus a wideband O2 sensor on vehicles without a factory wideband O2 sensor. The harness-only purchase does not include sensors or tuning. Confirm the required sensor components and calibration with FastUTV.

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.
