It has just a bit more timing and a bit more fuel over level 1. Level 2 Tune: This tune is developed for a Pro-R with aftermarket exhaust on 91-93 octane.This tune can be run with an aftermarket exhaust without any issue, but our level 2 tune is the best option for aftermarket exhaust as it's slightly richer for more power. This tune adds +10-11rwhp (15-16 crank horsepower) putting you at roughly 240 crank horsepower with just a flash! We would highly suggest our clutch kit with this tune to help with belt grip and gain additional low to mid range power. Level 1 Tune: This tune can be run on a bone stock Pro-R on 91-93 octane fuel.Currently no programmers like the PV3 are available and no ETA, so sending your ECU in for a bench flash is the only way to get a great tune. Works with all models including ones with Dynamix and/or evap models. AA's modified fuel curve will still get decent mileage cruising, but is corrected over the factory lean AFR when needed.ĪA ECU flash for 2022 RZR Pro-R 4 Cylinder Models **Requires ECU to be sent in for programming**.Many others simply focus on wide open throttle timing/fueling. AA's wicked timing curve is safe for the fuel used, but we do a much better job of finding timing limits for ramp up/more torque.Ideal peak RPM is 8200-8500 with the flash, but 8800 is for ramp up overshoot/top speed. Rev limit at a safe 8800 RPM(stock is 8650).More throttle % in low gear and reverse.
Speed limiter removed in low and high gears (Most will be able to run over 100mph!).The progressive fan also ramps up in quicker to keep you running cooler than OEM. Fan on/off at 185 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp.Much quicker throttle response and power delivery giving a whole new feel to the vehicle.Big horsepower gains depending on the level of tune/modifications(see below tune descriptions for more details).
