723251 Fits Twin Cam Touring 2008 2013 and Twin Cam Trike 2009 2013

Transform the performance of your Touring or Trike model with the ThunderMax EFI system. This self-tuning fuel management system replaces the stock ECM and uses wide-band AutoTune technology to refine your engine's tune in real-time. It is designed to work with any configuration, from stock bikes to those with high-performance exhausts and air cleaners. By constantly monitoring air-fuel ratios, it ensures maximum performance and fuel economy regardless of ambient conditions or fuel quality. Riders will experience a smoother engine, crisper throttle response, and the ability to adjust idle speeds for better heat management. Installation requires 18mm oxygen sensor bungs in the exhaust system. This system is an industry-leading choice for those who want a perfectly tuned Harley-Davidson without the need for constant dyno sessions.
