Evolution Powersports has released its long anticipated Polaris Ranger 900 Programming. Polaris limits the throttle opening of the stock Ranger programming to 50%. We reprogram this to allow 100% throttle. Huge horsepower gains have been realized through throttle opening, 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.
Evolution Powersports has vast knowledge of the Polaris Bosch ECU from our work in the automotive world. We have brought this expertise to the SXS market to extract the most performance from the Ranger 900 engines as possible. Your ecu must be sent to our Somerset WI facility for reprogramming - otherwise, pre flashed ECU's can be purchased outright for additional cost. You can also have your ECUs programmed by one of our Flashing Dealers (see Dealers section for a list of dealers with flash capability)
- Rev Limiters raised to 9000 for both high and low gear
- Improved throttle response in all modes (E-Gas Settings Improved)
- 100% Throttle in both high and low gear
- Improved ignition timing advance optimized for 91 Octane for maximum power
- Fueling adjusted for aftermarket components (intakes, exhausts and cat deletes) for optimal Air/Fuel Ratios No need to run a "piggyback" fuel controller with our reflash for most bolt on mods (You are responsibe to make sure your mods are compatible with our programming - All EVO and most other aftermarket companies' exhausts are compatible with our programming as well as all EVO intakes)
- Torque Limiters removed ("Shaft Saver delete") 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 Vmax Delete (Speed Limiter Removed)
