Yamaha announces an updated version of its Power Tuner app is now available for download.

As with previous versions, the free-of-charge application establishes wireless connectivity between the YZ/WR range of four-stroke motorcycles and the user’s smartphone, enabling easy adjustment of air/fuel mixture and ignition timing to fine-tune engine performance while supplying a wealth of data.

The new app will provide 2023 YZ450F owners with more functionality and improved user interface in an even easier to use app. New features include:

  • Intuitive Quick Setting slide bar for quick, easy engine mapping adjustments
  • Helpful new FAQ-style engine and suspension tuning guides
  • New integrated lap timer
  • New Traction and Launch Control tuning capabilities
  • Improved real-time information dashboard monitor screen

Simple Tuning with New Quick Setting Slide Bar

With Yamaha’s new Power Tuner App, 2023 YZ450F owners can opt to quickly modify engine characteristics on a range between Smooth and Aggressive by using the intuitive new Quick Setting slide bar. This single scrollbar offers seven different power delivery options for simplified tuning.

For owners wishing for more specialised tuning, the previously available grid matrix screen for both fuel injection (FI) and ignition timing (IG) allows a vast range of adjustments based on throttle opening and engine rpm/ The range of adjustments for FI and IG values has been significantly increased with this new app.

FAQ-Style Engine & Suspension Tuning Guides

To further simplify tuning, the app now includes helpful new engine and suspension tuning guides to assist users in finding their ideal setup. The engine tuning section provides a general overview and discusses the thought process behind using the FI and IG grid matrix screens to help guide riders toward reaching their desired power delivery settings.

Suspension guides are developed in partnership with KYB and include recommended settings and solutions for a wide variety of conditions and machine behaviours to help speed up the setup process.

Lap Timer Feature

A new lap timer has been added, controlled via the multi-function switch located on the left handlebar. After each ride, lap time data recorded to the motorcycle’s ECU can be checked via the app, allowing the user to better track the effects of setting changes through lap-by-lap analysis.

Traction and Launch Control Tuning

The YZ450F’s newly adopted Traction Control System offers three settings (LOW, HIGH, OFF) selectable through the Power Tuner App. The new Rev Limit feature added to the existing Launch Control System can be set in 500 rpm increments for optimum launches when the gate drops.

Improved Real-Time Dashboard Monitor

The new app’s smartphone monitoring functionality has also been expanded. In addition to previously available functions like the race log and engine diagnosis, an enhanced real-time monitoring screen displays motorcycle speed, throttle position, engine rpm, fuel consumption, coolant temperature, intake air temperature, battery voltage, smartphone battery level and the current time.

The new Yamaha Power Tuner App retains all the functionality of the previous version including ability to download/share maps, diagnostic features and programmable reminders. It includes three pre-loaded engine maps, and the rider can make on-the-fly selection between two designated maps using the motorcycle’s push-button handlebar toggle switch.

The new app is compatible with other Yamaha models that feature the Yamaha Power App – but note that some of the new functionality is exclusive to the 2023 YZ450F.

The app is free-of-charge on Google Play or the App Store.
