RVS Performance is the industry leader in Polaris ATV ECU tuning and clutching. We have released our Ranger 570 ReFlashes. We flash your ECU to our own custom tune. Huge 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 ATV market to extract the most performance from the Prostar 570 engines as safely possible. Your ecu must be sent to our shop in North Branch, MN 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. HP gains from 5+ at the wheels depending on tuning stage and supporting mods!

  • Speed Limiter Removed
  • Rev Limiters raised
  • Improved throttle response in all modes
  • Improved ignition timing advance optimized for 91 Octane for maximum power on all stages
  • Fueling adjusted for aftermarket components (intakes, exhausts) for optimal Air/Fuel Ratios
  • No need to run a "piggyback" fuel controller with our reflash for most bolt on mods (You are responsible to make sure your mods are compatible with our programming - Most aftermarket companies' exhausts and intakes are compatible with our programming)
  • Torque Limiters removed for a much more responsive and fun vehicle
  • Cooling fan on temperature is lowered by 20 Deg F, but can be set to whatever temperature the customer wants


Stage 1 - Stock exhaust and intake, 91 oct - 5HP

Stage 1.5 - Stock exhaust, aftermarket intake, 91 oct - 6HP

*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.
