The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to an iOS® or Android® device, allowing owners to adjust air/fuel mixture and ignition timing, log race set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time, and more. The newest version of the app has been revised to be more user-friendly, with new features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction Control tuning, lap timer, and helpful engine and suspension tuning guides.
