THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune — Black – 18-24 Softail

ThunderMax Engine Control Module Kit with Integral Auto Tune delivers closed-loop, wide‑band tuning and hundreds of downloadable maps for a tailor-fit calibration. 🔧🏍️

The kit includes the ThunderMax ECM with Auto-Tune module, plug-in harness, two wide-band oxygen sensors, TMax software and USB communication cable for map loading and live datalogging.

Load a map for your bike and the integral auto-tune will continuously self-adjust air/fuel ratio for all riding conditions without requiring dyno tuning.

Use the Windows software to monitor, record and analyze diagnostic codes, starts, engine temperature and rpm, and to adjust AFR maps, ignition timing, idle speed, rev limit and speedometer calibration.

Compatible with popular exhaust systems, high-performance camshafts and supports turbo, nitrous and supercharger applications; some aftermarket exhausts may need sensor port modifications for clearance.

Quick‑start installation replaces the factory ECM, installs the sensors and harness, loads the correct map and gets you riding fast; new maps, software and tech support are available online at no charge.

Made in the USA. Not interchangeable or upgradable from part # 1020-2118.
