THUNDERMAX ECM with Auto Tune - Non-Throttle By Wire 309-460

Factory ECM tuning is a compromise—it's built to satisfy EPA regulations and broad compatibility, not maximize your bike's performance. The ThunderMax ECM with Auto-Tune replaces that limitation with a closed-loop system that continuously adjusts your air/fuel ratio in real-time, delivering sharper throttle response, improved driveability, and the ability to properly tune for your specific modifications without a dyno visit. Whether you're running premium exhaust, aggressive cams, or forced induction, this is how modern performance tuning should work.

Installation is straightforward: bolt out the factory ECM, install the included wide-band O² sensors and harness, load your bike's map from hundreds of available options, and ride. The auto-tune module handles the rest, continuously self-correcting as you ride. Software updates, new maps, and technical support are free for life—no subscription, no surprise costs.
