Thundermax ECM with Integral Auto Tune System

Take complete control of your Harley-Davidson’s performance with the ThunderMax ECM with Integral Auto-Tune System from Kruesi Originals. Designed as a direct replacement for the factory ECM, the ThunderMax system continuously self-adjusts your motorcycle’s air/fuel ratio using advanced wide-band oxygen sensors for unmatched throttle response, ride quality, and engine performance.

Built for Harley riders demanding maximum performance and reliability, the ThunderMax Auto-Tune system automatically adjusts for riding conditions, engine modifications, exhaust systems, cams, air cleaners, and elevation changes without requiring constant dyno tuning. Simply install the ECM, replace the oxygen sensors, load the correct base map for your setup, and ride.

With hundreds of downloadable maps available, the ThunderMax system supports everything from mild bolt-on upgrades to aggressive high-performance bagger builds, including turbocharged, nitrous, and supercharged applications. Riders can also fine-tune idle speed, rev limits, ignition timing, and speedometer calibration for a truly customized riding experience.

Whether you're upgrading your Touring, Softail, Dyna, or Sportster Harley-Davidson, the ThunderMax ECM delivers smoother power delivery, improved rideability, optimized fuel management, and increased overall performance.
