What is ThunderMax ECM?

ThunderMax ECM is an award-winning, high-performance engine control module (ECM) specifically designed for EFI-equipped Harley Davidson® motorcycles. This advanced stand-alone tuning system utilizes AutoTune technology and wide-band oxygen sensors to optimize your bike's performance and rideability. It is the ideal solution for Harley Davidson® owners looking to achieve smoother throttle response, improved engine efficiency, and overall performance enhancement.

Key Features of ThunderMax ECM:

  • AutoTune technology for automatic fuel management
  • Wide-band oxygen sensors for precise air-fuel ratio adjustments
  • No wire cutting or splicing required—simple installation
  • 100% assembled and ready for installation right out of the box
  • Real-time feedback to optimize engine performance

Easy Installation for Instant Performance Enhancement

The ThunderMax ECM comes pre-assembled and ready to install, meaning you can quickly upgrade your Harley Davidson® with no complex wiring or modifications. Simply replace your factory ECM and oxygen sensors, load your desired map, and you’re ready to experience improved throttle response, smoother engine performance, and optimal fuel efficiency.

ThunderMax ECM Installation Process:

  1. Remove the factory ECM and oxygen sensors from your motorcycle.
  2. Install the ThunderMax ECM and connect the wide-band oxygen sensors.
  3. Load your map (or use the pre-programmed basemap) to begin automatic tuning.
  4. Start riding and enjoy smoother, more responsive performance!

AutoTune Technology for Precise Fuel Management

ThunderMax ECM features AutoTune technology, which automatically adjusts the air-fuel ratio at every 256 RPM and for every degree and a half of throttle. This automatic fueling adjustment ensures your engine operates smoothly and efficiently under all riding conditions.

The system also includes a built-in barometric sensor, which compensates for any changes in ambient air pressure, so you don’t have to manually adjust for changes in weather or altitude. The wide-band O2 sensors provide live, real-time feedback to the ECM, ensuring your motorcycle’s engine is always running at peak performance.

Benefits of AutoTune with ThunderMax ECM:

  • Automatic fueling adjustments every 256 RPM and degree-and-a-half throttle for smoother performance
  • Real-time feedback from wide-band oxygen sensors for precise air-fuel ratio control
  • Barometric sensor for automatic compensation based on changes in weather or altitude
  • No manual changes needed—once you turn off your bike, the adjustments are saved

Fully Adjustable Tuning for Custom Performance

The ThunderMax ECM is designed to be fully adjustable, offering the flexibility to fine-tune your bike’s performance based on your specific riding preferences. You can use ThunderMax tuning software to make advanced adjustments to fueling and engine settings, or you can simply load a basemap for quick and automatic tuning.
