THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune - Touring 309-591

Factory ECM limitations leave performance on the table—whether you're running custom exhaust, high-flow heads, or forced induction. The ThunderMax Engine Control Module Kit takes real-time closed-loop tuning into your hands, automatically adjusting air/fuel ratio and ignition timing across all riding conditions without a dyno visit. Installation is straightforward: bolt in the new ECM, swap the O2 sensors, load your bike's specific map, and ride with noticeably sharper throttle response and optimized performance.

What sets ThunderMax apart is its integral Auto-Tune module—it continuously learns and self-adjusts your tune based on live sensor data, meaning your bike stays properly calibrated whether you're cruising at part throttle or hammering through the gears. Combined with hundreds of downloadable maps tailored to your exact setup and free lifetime software updates, you get a professional-grade tuning solution that adapts to modifications without recurring dyno fees.
