Description

Would you like to have full control of your EFI system, freedom to make major or minor adjustments without the need for a dyno or a degree in computer technology? Here is a simple solution - ThunderMax with Auto-Tune! The ThunderMax is a product that replaces the factory module and is not an add-on box or signal modifier. The ThunderMax is purpose built to deliver uncompromising performance.

Just how easy is it? 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, each dyno-developed on real motorcycles. Choosing a basemap is a quick & easy process thanks to the software’s sorting filters; loading a map takes less than a minute. After that you’re ready to start the motorcycle, let the bike warm up at idle to operating temperature and you’re ready to ride! During your ride, the ThunderMax Auto-Tune system 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 injectors, fuel pressure, throttle body or exhaust flow. With every tank of fuel, at any temperature or elevation, your engine’s tune is optimized by ThunderMax.

Simply put, ThunderMax is the most advanced, yet user friendly, performance engine management system you can buy for your Harley. Using the supplied ThunderMax software and communication cable allows you to adjust and monitor virtually every parameter in the system. Installation and How-To Videos are available on-line
