AutoTune Technology: Real-Time Adjustments for Seamless Rideability

ThunderMax's AutoTune technology is what sets it apart. With this technology, the ECM continually adjusts the fuelingat every 256 RPM and every degree-and-a-half of throttle. This results in a smoother-running engine and increased control across all riding conditions. Whether you're cruising or accelerating, ThunderMax ensures your Harley Davidson® runs at peak performance.

How ThunderMax AutoTune Enhances Performance:

• Automatic fuel adjustments based on real-time data from wide-band O2 sensors.
• Every 256 RPM and throttle degree is adjusted for precise fueling.
• Barometric sensor automatically compensates for air pressure changes, ensuring your bike runs optimally in any condition.

With ThunderMax, you don’t have to worry about manually adjusting fuel settings or re-accepting tuning changes. The AutoTune technology takes care of everything for you, providing instant fueling corrections without intervention.

Fully Adjustable with ThunderMax Tuning Software

While ThunderMax ECM works excellently with its pre-loaded basemap, it is also fully adjustable using ThunderMax tuning software. This gives you complete control over your engine’s performance, allowing you to tweak everything from fueling to throttle response based on your preferences or riding conditions.

ThunderMax Tuning Software Features:

• Advanced tuning control for fuel management, throttle response, and more.
• Real-time adjustments for dynamic tuning during rides.
• Customizable settings to suit different riding styles or performance goals.

Whether you prefer the convenience of the pre-programmed basemap or want to fine-tune every aspect of your motorcycle's performance, ThunderMax gives you the flexibility to choose.
