Polaris RZR 900 Dynojet Power Vision 3 ECU Tuner

Precision ECU Tuning for the Polaris RZR 900

Unlock the full potential of your Polaris RZR 900 with the Dynojet Power Vision 3 ECU tuner. This handheld device connects directly to your machine's engine control unit, giving you the ability to load optimized calibrations, monitor real-time engine data, and diagnose fault codes — all from one compact tool.

Direct ECU Access
The Power Vision 3 reads and writes directly to your RZR 900's factory ECU. Load performance calibrations that adjust fuel mapping, ignition timing, and rev limits to match your modifications. Whether you're running an exhaust upgrade, intake kit, or clutch kit, the tuner adapts your ECU calibration to complement the changes.

Real-Time Data Logging
Monitor critical engine parameters in real time on the built-in color display. Track RPM, coolant temperature, throttle position, battery voltage, and more while you ride. Data logging lets you record and review runs to fine-tune your setup for peak performance.

Diagnostic Scanner
Read and clear diagnostic trouble codes directly from the ECU without needing a dealer visit. The Power Vision 3 gives you the same fault code access as a dealership scan tool, helping you identify and resolve issues quickly.

Stores Factory Calibration
Before writing any new tune, the Power Vision 3 saves a complete backup of your RZR 900's stock ECU calibration. You can restore the factory tune at any time, keeping your options open for warranty service or future changes.
