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 Polaris 1000/900/925T engines as possible. Your ecu can be sent to our Somerset WI facility for reprogramming otherwise, pre flashed ECUs can be purchased outright for additional cost. Please choose With ECU option for the outright purchase of a EVO pre programmed factory ECU. With this option, in most cases there is no need to send us your ECU. You can also have your ECUs programmed by one of our Flashing Dealers (see Dealers section for a list of dealers with flash capability).
