a Power Commander?
The Power Commander is a fuel injection and, on some
models, an ignition timing adjustment unit that
plugs 'inline' with the bike's stock ECU (Electronic
Changes are made to the bike's fuel and ignition
curves via the Power Commander's onboard
microprocessor. Using this technology we are able to
provide a wide range of adjustment without making any
permanent changes to the bike's ECU.
The Power Commander uses original-equipment style
connectors so that no splicing or cutting of the
harness is required. Simply removing
the Power Commander unit returns the bike to its
previous stock condition.
The top graph shows the horsepower curve
accelerating at a 40% throttle opening; the
lower graph shows the corresponding air/fuel
ratio. You can see a large horsepower
increase between the two. The red curve
shows a typical stock motorcycle with minor
performance modifications (slip-on exhaust).
The blue curve shows the same combination with the
Power Commander installed - you can see that the line
is nearly straight. So the rider will feel a
large improvement while riding the
motorcycle, whilst it's possible that the
peak, wide-open throttle horsepower remains
The Power Commander can be supplied
pre-programmed with your choice of several settings,
based on the modifications to your bike. The unit
also comes complete with software and cable link
that allows you to change between different maps or
make adjustments to a map file.
Dynojet Fuel Injection Tuning Link
The Dynojet Fuel Injection Tuning Link is an
innovative software application that allows the
automatic fuel curve optimization of a Power
Commander equipped motorcycle.
The Tuning Link
software interfaces the Power Commander with a Model
250 Load Control Dynamometer. The Tuning Link
software controls both the Dynamometer and the Power
Commander at the same time. By utilizing the Dynojet
'real time' air/fuel ratio monitoring equipment and
latest 'Load Control' Dynamometer technology, the
Tuning Link monitors the current air/fuel ratio at
over 140 different points. At the same time, the
Tuning Link automatically calculates the correct
fuel adjustment to achieve the optimal air/fuel
ratio. Once calculated, the Tuning Link uploads
these new fuel values to the Power Commander and
saves a copy of the file.
