Fuel Moto was fortunate
enough to be involved in product testing of the 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.
