Fast UTV aRacer ECU & Tuning Package
Transform your 2015+ Polaris RZR 170 with a complete, plug-and-play aRacer Super X PRO ECU package engineered and calibrated by Fast UTV. The stock RZR 170 produces approximately 11 horsepower at the crank and 6 horsepower at the wheels. Our Stage 1 calibration doubles measured wheel output to 12 WHP while removing the factory speed limiters, and the higher stages build from there.
The system is ready to run after installation and includes any three tuning levels from the four stages below. Every calibration is developed for stock engine internals. Required supporting upgrades are a full exhaust system, air intake system, and tunable clutch system.
