How You Ride, Where You Ride, Every Ride!
Would you like to have full control of your EFI system, freedom to make major or minor engine changes or tuning adjustments without a master’s degree in electronics and computers? Here is a simple solution—ThunderMax® with Wave Tune AutoTune! The ThunderMax® is a completely new product that replaces the factory electronic control module (ECM), not an add-on box or post-fuel signal modifier. The ThunderMax® is purpose-built to deliver uncompromising performance with advantages not possible with post-fuel or flash systems - but you don’t have to be a rocket scientist to install, program or make adjustments to it.

Just how easy is it? Installation is a straightforward plug-in replacement of the factory module and oxygen sensors*1. The ThunderMax® TMax Tuner software contains hundreds of base maps that cover most popular factory and aftermarket combinations, dyno-developed on real motorcycles. Choosing a map is a quick and easy process thanks to TMax Tuner’s sorting filters; loading a map takes less than a minute. After that, you’re ready to let the ThunderMax’s Wide-Band AutoTune system dial in idle and warm-up settings for your engine and you’re ready to ride!

During your ride, every time you ride, ThunderMax’s® Wave Tune AutoTune analyzes, adjusts and anticipates the air/fuel ratio read by the wide-band oxygen sensors at warp speed during 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 and exhaust flow. With every tank of fuel, at every temperature or elevation. That’s it! All you have to do is ride.

As simple as it is 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 Tuner software, you can adjust or monitor virtually every parameter of the system:

    • Idle Speed & Rev Limit
    • Closed Loop AFR Targets
    • Igniting Timing
    • Accel Pump Simulation
    • Start Fuel Pulse
    • Decel Pop Control
    • Speedometer Calibration
    • Read Diagnostic Codes
    • Running Statistics / Logs
    • Engine Temp Alarm
    • Live Engine Tuning
    • Live Monitoring & Recording
    • Dealer Digital Tech Compatible
    • Warm-up Settings
    • And More!


While this system does not require a dyno to achieve a smoother, cooler, excellent running engine, that does not mean it’s not a dyno-friendly device! Experienced tuners will appreciate its live-tuning capabilities with real-time monitoring and the ability to control all of the systems tuning parameters, knowing that AutoTune will keep the final tune from deteriorating as ambient conditions change. Advanced level software is available for technicians wishing to create a custom tune, add nitrous or install a forced-induction intake.

ThunderMax® also employs industry-leading tech support though its internal data-collection system that quickly communicates directly with the ThunderMax® support team should there ever be a need. ThunderMax® Technicians can quickly review recorded data streams, data stored within the module and information about the bike and system with just a few clicks of a mouse!

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. Each ThunderMax® includes an ECM, 2 wide-band oxygen sensors with harness, communication cable, software disk and comprehensive instructions. The ThunderMax® is designed and manufactured right here in the USA and backed by a 3-year warranty!

*1 ThunderMax® uses 18mm Wide-Band oxygen sensors, which unlike the factory narrow-band sensors read over the engines full rpm range for constant full-time feedback and adjustments. Certain year bike exhaust systems are equipped with 18mm sensor ports, others may have 12mm ports or none at all. Check application notes for compatibility.
