Research is a pretty familiar name in motorsports, founded back in
1972. In the three-plus decades since then, Dynojet has grown to
become a recognized world leader in the development and manufacturing
of a whole list of performance enhancing products and tools. Offering
a full complement of jet and slide kits for carburetors and all those
Power Commanders for fuel-injected bikes–and the state-of-the-art dynamometers themselves
to test and tune all of that–the name Dynojet has become just
about synonymous with optimized fuel management. When the goal is maximum
performance and increased overall efficiency, riders, racers, shops
and mechanics everywhere look to Dynojet.
Serving riders worldwide, Dynojet’s even partnered with a number
of other industry-leading companies in more than 25 countries to assure
that local technical support is always available–where it’s
needed and when it’s needed. With offices in Nevada, Montana, Holland,
England and Germany, Dynojet is never very far away. There are more than
4,000 dyno tuning installations established, including sites with OE
manufacturers, vehicle importers, exhaust-system manufacturers, tuners,
race teams, dealers and independent service shops. Establishing even
more credibility, Dynojet’s dynamometers are officially licensed
with AMA/ProStar, AMA SuperBike and NASCAR.
Right from the beginning Dynojet Research has relied on state-of-the-art
technology to provide the best products available. Very often those products
weren’t available anywhere else. In the carburetor years it was
jet- and slide kits. Now, with the motorcycle manufacturers almost total
use of fuel-injection, it’s the full line of Power Commanders and
their custom electronic fuel mapping. Dynojet runs a full schedule of
training classes for dealers, ensuring that customers get the most out
of their products, and the product line is constantly expanding with
new applications and features coming online all the time. That’s
a company philosophy that’s never wavered. Dynojet Research believes
in customer support, and that support filters right down to one-on-one
individualized attention if that’s what it takes.
After thirty-plus years in the industry, Dynojet Research has rightfully
claimed the Number One position in the field–street and track. 
Dynojet’s
mobile dyno-tuning center has become an invaluable fixture at the races.
Anyone (factory riders and privateers alike) racing at the track that
is using any Dynojet product can take advantage of their tuning expertise.
 or
more than a decade, Dynojet’s been a fixture at the AMA races.
With its mobile dyno-tuning center, Dynojet has helped countless
competitors tune their bikes to the optimum potential. For 2004
all that’s gotten even better; Dynojet’s brand-new
soundproof truck now allows that dyno-tuning support to be brought
right inside the track and set up right in the middle of things
next to all the teams, factory and privateer. The noise is no longer
an issue.
Dynojet’s support and tuning expertise is available at no charge
to anyone at the track who is racing and using any Dynojet product.
Anyone using a jet kit receives jetting advice and those with a Power
Commander receive a full fuel-curve mapping session. It’s a popular
service. At any time during the race meet it’s not unusual to
see 10 or 15 bikes waiting in line to get into that truck. The Dynojet
crew will open up for service at 8:00 in the morning and sometimes
they’re not done until 10:00 at night. With Dynojet sponsoring
Team Yamaha and Team Kawasaki it’s not unusual to see those factory
bikes at the truck as well. Tommy Hayden’s motorcycles were on
the dyno at every race this year. At one race, Dustin Schaller, Dynojet’s
man on the scene, remembers, “We had every Team Yamaha bike come
up to the truck at the same time, both the A-bikes and the B-bikes.
The entire team was at our truck, which certainly raised eyebrows”…and
credibility. If factory teams put their trust in Dynojet, why shouldn’t
you?
The Dynojet support crew goes to every AMA race, 11 events during 2004.
For the most part that’s the truck’s role, although on
occasion Dynojet will send this mobile tuning team out to dealer open
houses and so forth. And everywhere it goes everyone gets the same
treatment, whether it’s Factory Team Yamaha and Kawasaki, or
Joe-average racer. There’s a sign always posted outside the truck
attesting to just that. “Dynojet,” it reads, “is
here to support the people who support us.”
 The
new PCIII USB unit for the Polaris Sportsman 700 Twin EFI

Commanders for ATV’s. This simple-to-use, no hassle,
high-tech unit requires no splicing or cutting of the stock
harness and comes with all the necessary cable links and
software.

Polaris Sportsman 700 Twin EFI is the latest ATV to have a Power
Commander now available for it. It’s not just any Power Commander,
either. It’s the feature-laden PCIII USB.
Just like all Dynojet Power Commanders, the new Polaris unit uses
all the OE style connectors so there’s no cutting or splicing
of the stock harness required. The PCIII USB comes with all the
software and cable links needed to allow you to change between
different fuel-curve maps or make simple adjustments to an existing
map file, and that USB port makes for an instant and no-hassle
connection between the Power Commander and your computer. And like
always, the fuel curve can also be changed by simply using the
faceplate buttons on the PCIII USB. There’s a +FUEL adjustment
to richen the fuel curve in each area of the map, and there’s
a –FUEL button to tune the mixture leaner. All the changes,
made either by computer or those faceplate buttons, are made to
the ATV’s fuel curve via the Power Commander’s onboard
microprocessor. There’s a large area of adjustment available,
and it’s all done without making any permanent changes to
the ATV’s stock ECU (electronic control unit). Removing the
Power Commander instantly returns the ATV back to its stock condition.
But why would you want to do that? A Power Commander III USB opens
up the world of Dynojet-developed fuel maps, all written to optimize
performance with all the popular aftermarket exhausts, air filters,
and other tuning combinations. Those maps are supplied on a CD,
and they’re also available online at www.powercommander.com.
Plus, the PCIII USB is so easy to use. It connects instantly. Simply
power up the unit and plug-in the supplied USB cable between the
computer and the PCIII USB and you’re ready to tune. As soon
as you connect the PCIII USB to the computer and launch the software
the installed map is displayed, too. No searching through the files.
The PCIII USB even stores notes from the various maps in its onboard
memory making it really easy to see just which map is loaded and
any special instructions you might have added.
All PCIII USBs have a “cylinder trim” adjustment, too.
This allows you to offset fuel delivery between one or more cylinders.
Advanced users can precisely adjust the fuel curve for each cylinder
throughout the entire rpm/throttle position range. The PCIII USBs
software also allows you to compare two map files, and do it without
the Power Commander even being connected. There’s a numerical
display as well as a brand-new graphic display. Making things even
easier, every PCIII USB comes with a power-up adapter so you can
program new maps and interface with the Power Commander right on
your desktop. And finally there’s an expansion port ready
for any upcoming accessory Dynojet develops.
All of this is now available for
the Polaris Sportsman 700 Twin EFI and will soon be available for
the Polaris Sportsman 800 Twin EFI and the Suzuki King Quad 700
EFI. New applications are constantly being developed. Check out
the website at www.powercommander.com to see the latest.

New for 2005, Dynojet has developed a Power Commander unit for
BMW applications featuring “Wide Band” integration,
which will allow for a one-step adjustment of the fuel mixture
for steady-state cruise areas, along with the same high-resolution
tuning as the current PC models. |
 ust
around the bend, Dynojet will have a Power Commander module for
BMW applications featuring “Wide Band” integration.
What’s that? Simple: The new Power Commander will offer the
same high-resolution tuning as the current Power Commander models,
but will combine all that with a simple one-step adjustment of
the fuel mixture for the steady-state cruise areas. This area of
a fuel curve is often referred to as the “closed loop” range.
Dynojet’s replaced the less accurate OE narrow-band oxygen
sensor with a Bosch 5 wire LSU4 wide-band sensor. This allows exact
fuel settings for the closed loop area, rather than having to settle
for an overly lean stock setting. With an optimized air/fuel ratio
now available all the surging and poor running at constant highway
speeds becomes a thing of the past. Outside of the closed loop
area in the fuel curve all fuel adjustments are made in the same
manner as with any regular Power Commander, and all the maps for
common modifications will be available.
The BMW Power Commander uses all OE style connectors and it’s
a simple installation; as always there’s no cutting or splicing
involved. The complete kit, including the Wide Band oxygen sensor,
will be available for most BMW fuel-injected models including the
F650, R-Series Boxers (including the GS) and K Series machines.
The suggested retail is $495 and it’ll be in the Parts Unlimited
warehouses in 2005.
