RZR XP Turbo Tuning Info
The Bully Dog GT tuner and BMP custom tunes are the most lethal combination ever brought to the RZR world! We have extensively tested with the 2017-Up RZR XP Turbo to make the most horsepower possible using our state of the art dyno center. All of our tunes feature a locked throttle by wire along with a raised rev limiter, raised speed limiter, optimized timing curve, optimized boost map and optimized fuel curve. We offer various levels of tuning to best suite your needs. The level 3 tune is the max on pump fuel. We recommend going with another lower HP tune for the rare occurrence you run into bad fuel. This would allow you to tune down and still be able to safely continue your ride.
Our programming uses many inputs to control HP output safety:
1. After intercooler temp - influences timing and desired boost to prevent detonation and pre-ignition.
2. After turbo temp vs pre-turbo temp - keeps turbo in safe usable efficiency range.
3. After intercooler pressure - influences timing and fuel flow
4. Knock sensor - Detunes engine to a safe level if knock is indicated and maintains until key is cycled
Turbo XP GT Monitors and Data Logs: Speed, RPM, Baro (Pre Turbo Pressure), Throttle %, Battery Volts, Coolant Temp, Timing (MAG & PTO), Injector Pulse Width (MAG & PTO), Manifold Absolute Pressure, Perceived Engine Load %, Boost PSI, Target Absolute Boost/Pressure, Boost Temp Pre-Intercooler, Air/Fuel (with the purchase of additional system).
Many are having trouble tapping in boost gauges with this system. Since the GT runs off of the factory sensors, it will not give you any trouble. The other big benefit is the ability to read target boost. This shows you the values we program into the ECU. If your actual boost is lower than the target boost you know something is wrong (IE boost leak, ECU detune because of bad fuel.. ect).
