THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune — Black – 12-17 Dyna, 12-13, 15 Softail, 14-22 Sportster

The ThunderMax Engine Control Module Kit with Integral Auto Tune replaces the factory ECM to deliver precise air/fuel control and improved throttle response across all riding conditions. 🔧⚙️

The kit includes the ThunderMax ECM with Auto-Tune module, plug-in harness, two wide-band oxygen sensors, TMax software with USB communication cable, and a comprehensive user manual for quick installation and setup. 🧰

Hundreds of downloadable maps tailored to bike model and components let you load the closest map, then the integral auto-tune continuously self-adjusts the air/fuel ratio using closed-loop wide-band sensors — no dyno required. 📥🔥

Live monitoring and datalogging allow examination of diagnostic codes, number of starts, engine temperature and rpm; maps adjust ignition timing, AFR by cylinder, and startup tables, and the system supports turbo, nitrous and supercharger applications. 📈

Easy installation: replace the factory ECM, install the oxygen sensors and harness, load the correct map, and ride — free software updates and technical support are available online. 🇺🇸
