Evolution Powersports ECU Power Flash 2017-2021 Polaris RZR XP Turbo & Turbo S 168
These tunes will transform your already fast Turbo into an absolute animal! Podium proven time and time again, we relentlessly test and push limits to ensure our riders get the horsepower, boost and performance they CRAVE! Various power levels and performance tunes are available for both Stock and Big Injectors. See the charts below to help choose which Stage is right for you. *Each Tune is tailored for the specific components installed on your machine, so some Stages require additional hardware. Purchasing this EVP ECU Power Flash (Tune) requires you remove your vehicle's ECU and ship it. Alternatively, you can Tune Yourself by purchasing a Tuning Device.
EVP has made more power on this model than any previous generation stock turbo - stock injector vehicle Our tunes not only improve boost, fuel, timing, rev limit and speed limit changes, we also help the cooling system issues by lowering the fan on temperature by 20 Deg F. This makes a huge difference in the average temperature the engine operates at and prevents run away coolant temps on hot days and high loads. Each tune is customized with fueling corrections for intakes, exhausts, etc. Polaris made many changes to both the fuel system and tuning of the Bosch ME17 ECU. The biggest change is the fuel system was changed from a return style, rising rate setup to an automotive type return less configuration. The new hardware includes a separate fuel pump controller which varies the pressure to the fuel rail based upon input from an inline fuel pressure sensor and programming. The controller accomplishes this by raising and lowering the voltage to the pump. When the vehicle is keyed on, the fuel pressure initially rises to approximately 70psi. Once the engine is started, the fuel pressure drops to 40 psi and stays there until the engine sees boost pressure. In boost, the controller raises the fuel pressure back to 70 psi. The system makes for a much better running and safer setup as compared with earlier models. Tune Features Massive wheel horsepower gains Rev limiters raised by 500 RPMS both high and low gears - custom rev limits upon request Speed limiters raised: High gear-15 MPH Low gear-10 MPH Reverse-9 MPH No piggyback fuel controllers to mess with Dramatically lowered coolant temperatures by manipulating the fan on/off temperatures (EVP was the first company to do this) Stage Tune Suffix Identifiers: R: The Turbo Wastegate Crack Pressure Must Be Adjusted for Higher Boost (see our video on the 'Additional Information' tab) Non R: Tunes do not require any wastegate adjustment.
