Product Description
Polaris RZR XP 900 / RZR XP4 900 (2011-2014) Digi-Tune PRO
Taking air/fuel tuning to the next level, the Muzzy Digi-Tune uses the latest technology to provide one of the easiest and most accurate methods of tuning the Polaris RZR XP 900 and RZR XP4 900.
The Muzzy Digi-Tune PRO comes pre-programmed and optimized for each model. There is no mapping or re-mapping necessary. Adjustments for elevation and/or modifications can be done "on-the-fly" using three buttons on the faceplate.
WHAT'S THE PRO VERSION: What sets the new PRO version apart from the standard Digi-Tune is the ability to remove or add fuel from the stock curve which provides complete tuning flexibility.
WHY IT'S BETTER: The Digi-Tune is a load based fuel adder which works with the factory ECU. The Digi-Tune's simple push button interface and powerful load based technology renders complex table-based throttle position and RPM re-mapping systems a thing of the past.
LOAD BASED TUNING: The Digi-Tune ushers in the latest in tuning science – gone is the old throttle position and RPM (Alpha-N) based tuning, replaced by a powerful and highly effective LOAD BASED tuning methodology. Load based tuning is superior to old school systems because different CVT ratios place different loads on the engine. RPM and throttle position based systems cannot tell the difference from one ratio to another. The Digi-Tune knows the difference and adds the proper amount of fuel for every gear ratio, in every situation.
Features: Easy installation. No computer required. Adds or removes fuel - PRO version ONLY. Pre-programmed and optimized for each model. Easy adjustability. Water and shock resistant.
