Does Your EFI Bike Pop? Spit? Backfire? Start Hard? Run Hot? Deliver Poor Fuel Mileage and Performance? 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 module, 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 install it, program it or make adjustments.

Just how easy is it?

Installation is a straightforward replacement of the factory module and oxygen sensors*. The ThunderMax SmartLink software contains hundreds of base maps that cover over 80% of popular factory and aftermarket combinations, dyno-developed by Zipper’s on real motorcycles. Choosing a map is a quick and easy process thanks to SmartLink’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 Smartlink 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 injectors, fuel pressure, throttle body or exhaust flow. With every tank of fuel, at any temperature or elevation, your engines’ tune is optimized by ThunderMax!

As simple as we’ve made it 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.
