Huge horsepower & speed gains! The factory 60 or 68 horsepower (depending on year) Ranger 900 is very limited from the factory, and we are here to help. The Ranger 900 motor is essentially the same motor that is in the RZR 900 S. The key to more horsepower on this platform is opening the throttle fully by removing torque limits, and then gaining up RPM which is limited not only in programming, but by clutching also. In this tune we remove torque limitations holding back horsepower at all RPM's, extend rev limits, and tune fuel & timing tables for the higher R's. This combination provides excellent results and the horsepower/speed you are looking for! Clutching is HIGHLY recommended with this setup.
MUCH quicker throttle response and power delivery especially in high gear
100% Throttle in high and low gear, and more linear power in reverse gear
Throttle by wire limiters disabled
AA's wicked timing and fuel curve for either 87 or 91 octane
More mid range fuel for increased mid range power and response
Cooler running motor with the fan temps decreased to 195 on / 185 off
Factory speed limiters removed (Normally 50mph on a crew, 60mph on regular Rangers)
Regular cab models can see speeds from 70-75mph, and crew models can see speeds up to 65-70mph.
2 foot limits disabled (brake/gas at the same time)
Optional seatbelt limiter disabled
Rev limit raised to a safe 8600 RPM
Removed torque limits that keep the motor from revving higher
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
Crew cab models will need a cable extension if you plan on mounting the PVCX. If you plan on simply flashing and removing the PVCX, you would not need the extension.
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 85hp on 91 octane fuel. With the 87 octane timing curve, you would see around 80-82 horsepower. Peak power is made between 7900-8200rpm, 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 5-7 horsepower.
