The THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto-Tune is designed for select 2021–2024 Harley-Davidson Touring motorcycles. Manufacturer part number 309-591, this kit replaces the factory ECM and plugs into the existing harness. It includes an 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 system uses wide-band oxygen sensors and closed-loop control to continuously adjust the motorcycle's air/fuel ratio for changing riding conditions. Hundreds of maps are available for download based on factors such as motorcycle model, engine size, exhaust system, air cleaner, pistons and cams. The integral Auto-Tune system uses the selected map to support tuning without dyno tuning. Adjustable settings include front and rear cylinder air/fuel ratio maps, ignition timing maps, startup maps, idle speed, rev limit and speedometer calibration.
TMax software provides live monitoring, recording and examination of diagnostic codes and datalogs, including starts, engine temperature and RPM operation. The kit works with popular exhaust systems, is compatible with high-performance camshafts and supports turbo, nitrous and supercharger applications. Technical support, software, firmware updates and map analysis are available online at no charge.
