Does Your EFI Bike Pop? Spit? Backfire? Start Hard? Run Hot? Crappy Fuel Mileage? Would you like to have full control of your EFI system, freedom to make major or minor adjustments without a master’s degree in electronics and computers? Here is a simple solution - ThunderMax with AutoTune! The ThunderMax is a completely new product that replaces the factory Electronic Control Module (ECM), not an add-on box or signal modifier. The ThunderMax is purpose-built to deliver uncompromising performance but you don’t have to be a rocket scientist to program it or make adjustments.
Just how easy is it? In most applications, installation is a straightforward replacement of the factory module and oxygen sensors. The ThunderMax software contains hundreds of base maps that cover over 80% of popular factory and aftermarket combinations, dyno-developed on real motorcycles. Choosing a map is a quick and easy process thanks to the ThunderMax software’s sorting filters; loading a map takes less than a minute. After that, you’re ready to start the motorcycle. Once running, let the bike warm up at idle to operating temperature while the software automatically dials in idle and warm-up settings for that particular engine and you’re ready to ride! During your ride, every time you ride, the ThunderMax AutoTune module analyzes the air/fuel ratio read by the wide-band oxygen sensors at warp speed after every cylinder fire and makes any necessary adjustments to the injector pulse width to achieve the desired air/fuel ratio while compensating for variations in engine components such as injectors, fuel pressure or exhaust flow.That’s it! All you have to do is ride.
But as simple as we’ve made the ThunderMax to install and use, don’t be fooled into thinking that this not one of the most sophisticated systems you can buy for your Harley®. Using the supplied SmartLink software and communication cable, you can adjust or monitor virtually every parameter of the system:
ThunderMax makes more sense in the long run as the system can grow and change as your engine does - just load a new map! ThunderMax software, firmware and maps updates are free and accessible 24/7 with an Internet connection so you’re only a mouse-click away from the latest available data. The ThunderMax is designed and manufactured right here in the USA and backed by a 3-year warranty!
