Because of possible clearance issues, some aftermarket exhaust systems may require modifications or relocation of their O² sensor port bungs. This ECM uses 18mm wide band o2 sensors! If your exhaust does not currently have 18mm ports you will need to weld new ones in! Bungs available here! ThunderMax is an industry award-winning, performance ECM designed specifically for EFI-equipped Harley Davidson® motorcycles. This highly advanced, stand-alone tuning system utilizes proprietary AutoTune technology with wide-band oxygen sensors to deliver unmatched performance and rideability. ThunderMax comes 100% assembled, and ready to install with no wire-cutting or splicing required. Simply replace the factory ECM and oxygen sensors, load a map, and enjoy your new ride! Every degree and a half of throttle; every 256 RPM, there is a fueling point that is automatically adjusted. That means more control and a smoother running engine. With the built-in barometric sensor, you never have to think about ambient air changes. WideBand O2 sensors constantly read the Air Fuel Ratio and give live, real-time feedback to the ECM. That means, no “accepting” the changes made to the map, once you key off the changes is written. The ThunderMax ECM is fully adjustable with our ThunderMax tuning software or can be used just by loading a base map. The choice is yours. Click here to view software downloads!
