The locked factory ECU era is over. Replace the factory ECU with the Acclivity Axiom stand-alone controller and FastUTV calibration for your 2022+ Polaris RZR Pro R. 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.

- 211 wheel horsepower
- Stage 4 | 110 octane
- 215 wheel horsepower
Stage 5: E85 and BC Stage 2 Cams
The $3,499.00 complete package includes the Acclivity ECU, BC Stage 2 camshafts, required software activations and FastUTV Stage 5 E85 calibration. Camshaft installation must be completed and verified before final calibration. Installation and dyno time are not included.
- Stage 5 | E85

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.
Stage 1-5 figures are naturally aspirated targets, not boosted horsepower claims. Flex-fuel output depends on the verified vehicle configuration. No turbocharger, supercharger, upgraded injectors or fuel pump is included in the packages listed above.

- R.I.D.E. modular control architecture with drive-by-wire, CAN communication and PWM-capable outputs.
- Configurable high-impedance injector drivers and programmable trigger/digital inputs.
- Internal high-speed logging, live tuning, diagnostics and calibration management.
Fitment and Setup
2022 and newer Polaris RZR Pro R UTV models. 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.
Shipping and Pickup
Continental-US ECU shipping uses FastUTV's $25 flat-rate ECU service. Corona pickup is available after order-readiness confirmation at 160 Vander St, STE C, Corona, CA 92878. No immediate shelf stock is implied.
