ThunderMax Engine Control Module Kit with Integral Auto Tune - '04-'13 Dyna/Softail/Sportster

The ThunderMax ThunderMax Engine Control Module Kit with Integral Auto-Tune offers a comprehensive tuning solution for Harley-Davidson models from 2004 to 2013, including Dyna, Softail, and Sportster bikes. This kit replaces the factory ECM with a plug-in ThunderMax ECM that mounts directly in place of the stock unit, providing a seamless upgrade that enhances engine performance and driveability. The package includes a plug-in harness, two wide-band oxygen sensors, TMax software, and a communication USB cable, enabling quick and straightforward installation. The system's compatibility with various exhaust systems, high-performance camshafts, and forced induction setups like turbo, nitrous, and superchargers makes it versatile for a wide range of custom builds.

ThunderMax’s Auto-Tune module continuously adjusts the air/fuel ratio for optimal combustion under all riding conditions. Using wide-band oxygen sensors and a closed-loop control system, it self-tunes on the fly, removing the need for traditional dyno tuning. Hundreds of downloadable maps tailored to your bike's specifics—such as model, engine size, and modifications—allow riders to select a base tune, and the auto-tune feature handles the fine-tuning automatically. The included TMax software provides live data monitoring, recording diagnostic codes, engine temperature, RPM, and other critical parameters, giving riders insight into engine performance and health.

Adjustable features include front and rear cylinder AFR maps, ignition timing, startup maps, idle speed, rev limits, and speedometer calibration, giving users control over their bike's tuning parameters. The system improves throttle response, exhaust sound, and overall rideability, offering a significant upgrade over stock ECMs. Made in the USA, the ThunderMax ECM kit supports modern tuning needs without requiring dyno sessions, saving time and money. Regular software, firmware updates, and technical support are available online at no charge, ensuring your tuning setup stays current with evolving technology and your riding preferences.
