Fuel Moto was fortunate enough to be able to test and evaluate the new soon to be released Zippers Thundermax with Auto Tune for 2008-2010 drive by wire Touring models. As you know this product has been in development for some time, but if you have an understanding of control systems developing a complete ECM including reverse engineering it to work with the stock harness and all of the other components and functions is no easy task. The final result is an excellent product.



There are many new updates to the new Thundermax. A welcome change is a standard USB connector for linking up to the Smartlink software, gone is the RS-232 DIN connector as used on other models. The new Thundermax also now has the ECM and Auto Tune modules integrated into one unit. There is less wiring and the harnesses for the Bosch Wideband sensors now plugs directly into the side of the Thundermax unit and is secured by 2 screws. The O2 harness wires are very durable and are silicone covered for protection from heat and the elements. The Thundermax unit itself is contained in a very nicely CNC machined case and is very durable.



Install is very straight forward. You basically start by removing the ECM fuse, unplug and remove the stock ECM and replace it with the Thundermax unit, replace the stock nb sensors with the included Bosch LSU 4.2 sensors, plug in the O2 harness, re-install the ecm fuse and the install is complete. Unlike the earlier models, you do not need to initialize the unit as there is no IAC. For the software you will simply run the included CD and once loaded run the updater and it will automatically look for any new updates and will give you the option od downloading them. This will keep your software and calibration list up to date. Before connecting to the software for the first time you will need to install the driver which is very straight forward. Once linked up the Smartlink software will check the unit for firmware and upgrades and if needed download them. The software itself is for the most part just like the earlier Smartlink with several updates and is very straight forward and easy to use. You have full control of the fuel, ignition, AFR tables, as well as many other utilities such as idle RPM, rev limiter, decel fuel, speedo calibration, and others.



We got the Thundermax installed on our 2010 bike in about a half hour. Started the bike and put it up on the dyno for some testing. We went thru the gears and tested several different features in the unit. Our bike currently has a Rinehart true dual exhaust and stage 1 air cleaner and there was a Thundermax calibration for this exact setup. I was very impressed at the accuracy of this calibration, I spent the better part of an hour on the dyno reading the wideband from the dyno as well as both Thundermax O2 sensors in the Smartlink software all of which are in real time. There were some areas where the Thundermax made some changes, others where the calibration was right on. The unit adapted to changes very quickly and very accurately. I even purposely richened and leaned and map to see how the Auto Tune would react and it very quickly correct them to the target AFR. In all, the new Thundermax is an impressive unit and will be another great option for those looking for a very flexible product.

This is a screenshot I took while running the bike on the dyno, note the accuracy of the AFR. The target AFR and the actual front and rear AFR are within three hundreths of a point.

 

Sounds interesting but all these devices seem to require hook up to a computer before they will work. If it is supposed to be plug and play and is "self-learning" why is an immediate download from a computer necessary? Will it work with a Mac or is it only compatible with Windows? When is it supposed to be available?

 

It's simply to have a programming starting place closest to the hardware on the bike. It doesn't learn and program the bike in an instant. It takes time while you're out riding around going various speeds with various throttle positions with various loads on the bike like hills or a passenger.

I went with the TTS but sometimes I wish I would have gone with the T-Max. The end result is the same but the T-Max is easier with fewer steps to get it there.

 

Correct, the Auto Tune still requires a base calibration to work off of. The more accurate the base cal the more accurate the Auto Tune will be with its fuel trim adjustments and maintaining the tune.
