ThunderMax ECMs & Auto-Tune

ThunderMax ECM kits replace your factory ECM with a self-tuning engine controller. Wide-band oxygen sensors and closed-loop Auto-Tune adjust your air/fuel ratio as you ride, so pipes, air cleaners and cams run right without dyno tuning. Kits include the ECM with Auto-Tune module, harness, sensors, software and a USB cable, and are made in the USA.

Also From ThunderMax and Thunder Heart

Shop replacement O2 sensors, pigtail harnesses, a stand-alone Twin Cam ignition, an M8 oil cooler fan and Thunder Heart harness controllers for custom builds.

Find the Right ECM

ECM kits are specific to your model family, year range and engine. Use the bike search and check the fitment chart on each product before you order.
