Fuel Controllers

There are so many components in a UTV, and keeping each of them maintained helps make your vehicle run better and last longer. Fuel tuning, an instrumental measure of how your UTV is running, is no longer just for mechanics and professionals. PJ’s Performance is excited to offer you an at-home alternative from our friends at Muzzys.

Muzzys is taking air and fuel tuning to the next level with the Muzzy Digi-Tune. The Digi-Tune uses the latest technology to provide one of the easiest and most accurate methods of tuning your fuel injected quad.

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.

Every Muzzy Digi-Tune comes pre-programmed and optimized for each model.  There is no mapping or re-mapping necessary. It’s easy to adjust the tuner for elevation using the three buttons on the faceplate. Because the Muzzy Digi-Tune is so user-friendly, you can get a better ride experience with ease.

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.

*Not compatible with all air/fuel meters. Air/fuel meter must have 0-5 volt output. Please specify Air/Fuel meter being used at time of purchase. The Digi-tune PRO may require air/fuel meter specific programming prior to shipping.
