Evolution Powersports Polaris RZR 900 ECU Programming
This ECU reflash unlocks significant horsepower gains through optimized timing, fueling, torque limit modifications, rev limiters, and speed limiters. The OEM programming restricts throttle opening and engine power. Our tune enables 100% throttle opening to extract 15+ wheel horsepower on 2015+ models with stock intake and exhaust. Older models gain 5+ wheel horsepower, with even larger gains possible when combined with aftermarket intake and/or exhaust components.
Built with enhanced safety features, the programming lowers the cooling fan activation temperature by 20°F from the OEM setting (which exceeds 200°F). Fan on/off temperatures can be customized based on your location and typical riding conditions. Turf Mode and ADC features are preserved on compatible vehicles.
Key Features:
- 15+ wheel horsepower gain on 2015+ models with stock components; 5+ on older models
- Rev limiters raised to 9000 RPM for both high and low gear
- Improved throttle response in all modes with optimized E-Gas settings
- 100% throttle opening in both high and low gear
- Ignition timing optimized for 91 Octane fuel
- Fueling adjusted for aftermarket intakes, exhausts, and cat deletes
- No piggyback fuel controller needed for most bolt-on modifications
- Torque limiters removed for improved responsiveness
- Cooling fan temperature lowered by 20°F (customizable)
- Speed limiter raised
