RVS Performance has released its Polaris RZR 1000-S ECU reflash. Big horsepower gains have been realized through timing, fueling, and torque limit modifications. We also build additional safety into our tune by lowering the fan on temperature by 20 deg F. The OEM fan on temperature is is too high (well over 200 deg F). In addition the fan on/off temperatures can be set for each customer depending upon where they live and the conditions typically ridden in. Other great features are added and/or changed to enhance the drivability and fun factor of the vehicle. We have brought our vast experience to the SXS market to extract the most performance from the RZR 1000/900 and Ranger 900 engines as possible. 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.
*Intake modification means a snorkel kit or air box modification that allows more air to flow through the intake system. In most cases an aftermarket air filter does not qualify as the restriction points are typically the inlet into the air box.
*Aftermarket exhaust can be a slip-on or full system. Please tell us what exhasut you are running in the special instructions box at checkout.
Turn around on ECU tuning is typically 1 business day and free return shipping is USPS Priority mail 2-3 days in the US.
