  • 2015+Rzr 900 ECU Reflash

    Free Shipping!

    RVS Performance is your industry leader in Polaris ECU tuning. Leading the way with the Ranger and RZR 900 and continuing to add more machines as fast as we can. Huge horsepower gains have been found through removing throttle limits, adjusting timing, fueling, and torque limiters. We also build additional safety into our tunes by lowering the fan ON temperature by 20 deg F. The OEM fan ON temperature is set to high (well over 200 deg F). In addition the fan ON temp can be set to each customer depending on where they live and the conditions typically ridden in. Other features are added and/or changed to enhance the drivability and fun factor of the vehicle. We have brought our 20+ years or performance tuning to the SxS market to extract the most performance from the RZR 900 engine as possible while keeping reliability and safety in mind.

    Your ecu must be sent to our shop for reprogramming - otherwise, pre flashed ECU's can be purchased outright for additional cost. With this option, there is no need to send us your ECU.
