Big horsepower & speed gains! The factory 570 Ranger is just like the RZR and ACE 570 is very limited from the factory. The 45hp motor is capable of much more and we are here to deliver! The factory limits you with torque limits to only allow so much horsepower to be made, very low 50mph speed limits, and a very timid rev limit. We unlock everything in this motor to gain another 5-7 horsepower. You'll notice MUCH quicker throttle response and power delivery especially in high gear.
100% Throttle in high and low gear, throttle by wire limiters disabled (on those models with TBW)
AA's wicked timing and fuel curve for either 87 or 91 octane
More mid range fuel for increased mid range power and response and a better fuel curve all around
Cooler running motor with the fan temps decreased to 195 on / 185 off
Tuner will allow you to view and erase most trouble codes
Easily program back to stock or switch tunes if needed
Easily data log 25 parameters on the fly and review on a Windows computer later
Choose between different tunes for 87 octane or 91 octane
Level 1: the most common and is meant for the factory exhaust system, and no other major engine modifications. When properly clutched, this tune is capable of 52-53+hp on 91 octane fuel. With the 87 octane timing curve, you would see around 50 horsepower. Peak power is made between 7500-7700rpm, so clutching is highly recommended for best performance.
Level 2: has all the features of the level 1 tune, but the fueling is designed for an exhaust system. Gains would depend on the exhaust that you are using, but normally would show another 3-5 horsepower.
Due to the time to it takes to custom program these tuners, we will ship within 24-48 hours of purchase.
