MAXimum Performance from Your EFI When You Ride, Where You Ride, Every Ride!
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 program it or make adjustments.
Just how easy is it? Installation is a straightforward replacement of the factory module and oxygen sensors*1. 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 or exhaust flow. With every tank of fuel, at any temperature or elevation. That’s it! All you have to do is ride.
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, you can adjust or monitor virtually every parameter of the system:
Closed Loop AFR Targets
Decel Pop Control
Read Diagnostic Codes
Running Statistics / Logs
Accel Pump Simulation
Start Fuel Pulse
Engine Temp Alarm
Injector Size Compensation
Live Engine Tuning
Digital Tech Compatible
New – Map Analyzer feature assesses AutoTuned map adjustments in a snapshot to simplify map analysis
New – AutoMap Creator feature speeds AutoTune mapping and improves the tune of any engine and exhaust pipe combination
And Many More!
The 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 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!
