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.

SPECIAL NOTE FOR 2014-2016 TOURING MODELS - ThunderMax® includes wide-band, 5-wire oxygen sensors that thread into 18mm x 1.5mm bungs located near the exhaust port, same thread size and location as stock narrow-band, 2-wire sensors used on 2008 and 2009 Touring model exhausts. Starting with 2010 models, all Touring bikes are equipped with a catalytic converter in the headpipe collector area. The oxygen sensors used by H-D®; on 2010 and later Touring models are smaller (12mm threads) heated 4-wire, narrow-band sensors located just forward of the catalytic converter near the transmission. The ThunderMax® sensors must be mounted in the 2008-2009 location, up near the cylinder head exhaust port. If you are retaining the original equipment 2010 and later exhaust header or have already purchased a pipe configured for 2010-2016 style 12mm sensors, 18 x 1.5mm bungs will need to be added to the existing headers in the upper location (near the exhaust port as on 2008 and 2009 models), with the lower 12mm sensors removed and ports capped. If using a not-yet-purchased aftermarket exhaust pipe, order an exhaust system for a 2009 model (pipe fitment is the same for 2010-2016 models) and your ThunderMax® sensors will install without modification. If you already have an aftermarket exhaust designed for a 2010 and later model Touring bike, you will need to install bungs as mentioned previously if the system is not equipped with dual bung locations.

100% SATISFIED Review by BRAD
“I was skeptical at first. I did a lot of research and decided I wanted to do all of my own work on my new toy. I am more than 100% satisfied. My buddy kept bugging me to go for a ride and I knew all he wanted to do was line ‘em up. My little stock 96' walked away from his 103' Super Tuner®!

I wanted a RELIABLE, strong running bike and that's exactly what I've got. Thanks

AWESOME Review by lo
“My bike runs awesome!” (Posted on 9/29/2017)
Waiting for Harley to do something good, finally I bought a 2014 Ultra Limited . Love the changes and handling but unsatisfied with the drive train. Based on past experience with the Zippers Service, Support, and Products I decided to run the combination of a Zipper’s High Flow Air Kit, the ThunderMax, and a set of RCXHaust.

Simple – Clean, woke the 103 right up. Before, the response was very unstable – issues with throttle response below 2000 RPM and always felt restricted on WOT. After – very responsive at any PRM, the 'Beach' (sand beige and brown) pulls hard thru top end.

Thanks to the Zipper’s crew. Thru the years of HDRA racing and upgrading my client engines they have continued to provide top notch product and service. And, for the few issues with tweaking the TMAX to a client’s bike, the TMAX Support team has been right on top of analyzing captured data and providing recommended processes. Satellite Dave 5/16/14

2014 Streetglide Review by Eddie
This is my third T-Max. First on a 2008 RK that I modify to the max and it performed great. Next was a 2012 Streetglide with cams and exhaust upgrades that ran great. Now I have a 2014 Streetglide that I have taken to 110 ci. with SE266E cams, ported and polished heads, 58mm throttlebody and of course intake and exhaust upgrades. I cheat a little with 100 octane fuel from my local airport. The performance of this bike is unbelievable and with the Thundermax I will never outgrow the tuner. I have done all of this myself with the support of the techs at Zippers who always get back to me within a couple of hours. Thanks guys. (Posted on 7/28/2017)
