AutoTune Technology: Real-Time Fueling Adjustments for Optimal Performance

One of the standout features of ThunderMax ECM is its integration of AutoTune technology. This technology uses wide-band oxygen sensors to automatically adjust fueling in real-time, providing a smoother, more responsive engine performance.

How ThunderMax AutoTune Works:

  • Automatic fueling adjustments are made at every 256 RPM and 1.5-degree throttle increment for more precise control.
  • Wide-band oxygen sensors continuously monitor and optimize the air-fuel ratio for peak engine efficiency.
  • The built-in barometric sensor adjusts fueling based on ambient air conditions, ensuring your bike runs optimally regardless of altitude or weather changes.
  • Real-time feedback means you don’t have to manually accept adjustments—the changes are written automatically once you turn off the bike.

Benefits of AutoTune Technology:

  • Improved throttle response and acceleration.
  • Smoother, more consistent engine performance.
  • Optimized fuel efficiency for a better ride.
  • No need to “accept” changes—everything is done automatically.
