Thundermax - Electronically Commutated Motor W/ Auto Tune fits '21 & Up Softail Models

Thundermax is THE name to know if you own an EFI-equipped Harley-Davidson motorcycle. Their standalone tuning system is top-of-the-line, combining proprietary AutoTune technology and wide-based oxygen sensors to provide unbeatable performance and rideability. It comes 100% assembled and ready to install, wire-cutting and splicing not necessary! All you have to do is replace the stock ECM and oxygen sensors, load a map, and get to ridin'! With this tuning system in tact, a fueling point is automatically adjusted at every degree-and-a-half of throttle. In other words, you'll have greater control and a smoother engine! There's a built-in barometric sensor which ensures you won't have to worry about ambient air changes. The WideBrand O2 sensors constantly read the Air Fuel Ratio and deliver live, real time feedback to the ECM. Translation: you won't have to "accept" the changes made to the map, as soon as you key off, the changes are written.

Whether you use Thundermax's exclusive tuning software or simply load up a basemap, this ECM is fully adjustable any way you like it!
