Remember the accelerator
pump in carburetors?
You’d crack open the
throttle hard and that
pump would squirt out a
nice shot of extra fuel right when
it was needed. A sudden increase
in the air flow—like what happens
when you turn up the wick hard
and fast—requires an equal
increase in fuel to keep an engine’s
power delivery smooth, steady
and seamless, and that’s just what
that accelerator pump
did. And it worked
great, too, remember?
That fuel-delivery
function is now part of
the EFI world and the
Power Commander. An
accelerator pump
utility is available as an
upgrade for all PCIII
USB models, it’s easily
downloaded directly
from the Dynojet website, it’s easily
installed, and it’s FREE!
Here’s what’s involved. Simply
download the “Accelerator Pumpâ€
utility file from
www.powercommander.
com, connect your Power
Commander III USB to your computer
and then load and run the
utility. And, just like with those
old accelerator pumps of days
gone by, the ones in carburetors,
the Dynojet accelerator pump
function for today’s EFI systems is
totally adjustable. You can vary
the amount of extra fuel added,
set the throttle action that’ll trigger
the “pump†function, and you
can set for how long that extra
shot of fuel is added. Unlike
adjusting a carburetor’s accelerator
pump, though, there are no
screws to turn, no tangs to bend,
no pins or links to move around.
Adjusting the accelerator pump
function on a Power Commander
all happens with a keyboard and a
mouse, and it’s simple.
Once you’ve downloaded and
launched the new utility, select
“Enable Accell Pump Feature.â€
(Make sure you have your Power
Commander connected.) Launch
the Power Commander software,
and on your laptop’s screen you’ll
find the “Accelerator Pump†function
under the “Power
Commander Tools†drop-down
menu. Configuring, or tuning, the
accelerator pump happens right
here. There’s a “Sensitivity†setting,
an “Engine Revolutions†setting,
and a “Percentage Of Fuelâ€
setting, and the values you enter
for each determines how the
accelerator pump reacts, how
quickly it reacts, how much extra
fuel is added, and for how long.
With a little experimentation and
some road testing you can dial in
exactly the response you’re looking
for.
The “Sensitivity†scale adjusts
the speed at which the throttle
must be opened to activate the
accelerator pump. The more sensitive
you make this setting the
slower the throttle movement
required to activate the “pump.â€
The “Engine Revolutions†setting
determines how long the extra
fuel will be added, anywhere from
just 1 RPM to 40. The “Percentage
Of Fuel†sets the amount added.
That’s it.
Now, what are the ideal settings?
That’s going to vary.
Different riders on different bikes
might want different settings.
Some racers, for example, have
found that a 75 percent
Sensitivity, 20 percent Fuel
Increase, and 15 Engine
Revolutions worked just fine for
them. Some street riders, on the
other hand, have had great results
with a 90 percent Sensitivity setting,
15 percent Fuel Increase, and
20 Engine Revolutions. The best
setting for any bike depends on
the bike and riding style of the guy
on it. It wouldn’t be at all unusual,
either, for different riders on the
same bike to choose different settings.
It wouldn’t be hard to
change those settings, either.
Pretty neat, wouldn’t you say?
Dynojet’s Accelerator Pump function
is applicable for all PCIII USB
models. Sorry, Power
Commander II and III hardware
don’t support the function. But if
you already have a PCIII USB get
online now and get the
Accelerator Pump. It’s ready right
now, and it’s FREE!
