THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune — Black – 20-24 Touring, 21-24 Trike, 21-24 CVO

ThunderMax Engine Control Module Kit with Integral Auto Tune delivers closed-loop, wide-band tuning that continuously self-adjusts to optimize the motorcycle's air/fuel ratio for all riding conditions. ⚙️

• Includes ECM with Auto-Tune module, plug-in harness and two wide-band oxygen sensors for precise closed-loop control.
• Hundreds of downloadable maps for bike model, engine size, exhaust and cam configurations — load the map of your choice and the integral auto-tune will do the rest.
• Live monitoring, recording and diagnostic datalogs including number of starts, engine temperature and rpm.
• Adjustable front and rear cylinder AFR maps, ignition timing, startup maps, idle speed, rev limit and speedometer calibration.
• Compatible with popular exhaust systems and high-performance camshafts; supports turbo, nitrous and supercharger applications.

Easy installation: replace the factory ECM, install the oxygen sensors and harness, load the correct map for your bike and ride; does not require dyno tuning, though some aftermarket exhausts may require sensor-port modification for clearance.

New maps, software and firmware updates, map analysis and technical support are available online at no charge. Made in the USA.
