The THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto-Tune is designed for select 2018–2020 Harley-Davidson Softail motorcycles. Manufacturer part number 309-589, the kit includes a ThunderMax ECM with Auto-Tune module, plug-in harness, two wide-band sensors, TMax software, a communication USB cable, a Quick-Start Easy Install guide, and a Comprehensive User's Manual.
The ThunderMax ECM replaces the factory ECM and plugs into the existing harness. Installation involves replacing the factory ECM, installing the new oxygen sensors and harness, loading the correct map for the motorcycle, and riding. Hundreds of maps are available for download based on motorcycle model, engine size, exhaust system, air cleaner, pistons, cams, and other configurations. The integral auto-tune system uses wide-band oxygen sensors in a closed-loop control system to continuously adjust the motorcycle's air/fuel ratio for riding conditions.
TMax software supports live monitoring, recording, and examination of diagnostic codes and datalogs, including number of starts, engine temperature, and RPM operation. Adjustable front- and rear-cylinder air/fuel ratio maps, ignition timing maps, and startup maps are supported, along with rider adjustments for idle speed, rev limit, and speedometer calibration. The system is compatible with popular exhaust systems and high-performance camshafts, supports turbo, nitrous, and supercharger applications, and does not require dyno tuning. Technical support, software, firmware updates, and map analysis are available online at no charge. The product is made in the USA.
