ECU hardware for customers arranging their own calibration. $2,399.00 retail price. This Acclivity Axiom ECU replaces the supported factory controller without factory ECU unlocking. No FastUTV tuning, fuel maps or turn-key calibration are included.
Included and Not Included
- Vehicle-specific Acclivity Axiom ECU.
- No FastUTV tuning or calibration service.
- Paid software-feature activations are optional and purchased separately.

Choose Your Expansion Harness
Select ECU only, or add one compatible Polaris expansion harness using the configuration selector. No expansion harness is included in the $2,399.00 base price. Core and Apex are alternative configurations, not a requirement to buy both.
- Axiom Core Harness | Add $209.00 | $2,608.00 with ECU
- Manufacturer part number: PN-22490-1. Connections: Boost control, Flex fuel, AFR.
- Axiom Apex Harness | Add $309.99 | $2,708.99 with ECU

Harness connection support does not include sensors, a switch, boost-control solenoid, tuning or software entitlements. Purchase required features separately and have your tuner verify the complete configuration. Gallery images show the ECU, software and optional harness configurations. Included hardware is determined by your selected configuration, not every item pictured.
Choose Optional Software Upgrades
Select individual software activations needed by your tuner. FastUTV arranges manual dealer activation after checking ECU identification and compatibility. Activation is not a calibration and does not include physical hardware. Rolling Anti-Lag and Rolling Launch remain coming soon and cannot be purchased.
Staged Injection Control is the eight-injector version. Can-Am DESS is not offered for this vehicle.
Calibration Required Before Use
A suitable calibration must be installed and verified before starting or driving the vehicle. Plug-and-play describes the hardware connection, not readiness to run without tuning.
