he Polaris RS1 is a game changing vehicle. EVP is the first to dyno and tune this unique vehicle and have achieved significant horsepower gains through timing, fueling, torque limit modifications, rev limits, speed limits, etc. 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. NEW- Revised decel fueling - eliminates the lean pop that the stock tune has when running an aftermarket exhaust! Rev Limiters raised 100% Throttle Improved throttle response in all modes (E-Gas Settings Improved) 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) Engine Speed TQ Limiters removed ("Shaft Saver delete") Vmax Delete (Speed Limiter Removed)
