The Model 250i Load Control Dynamometer is perfect for engine break in , durability testing and fuel injection mapping. It's like getting two Dynos in one package, as all the features of the Dynojet Inertial Dynamometer are maintained.
The Dynojet Load Control System was developed through years of experience with over 3,900 dynamometer installations worldwide. The design is easy to operate and provides the function of steady state load control.                         




Power Commander

What is Power Commander?

The Power Commander is a fuel injection adjustment unit that plugs "inline" with the bike's stock ECU (electronic control unit). The PC uses original equipment style connectors, so no splicing or cutting of the harness is required. Most installations take less than 15 minutes, some as little as 5 minutes.

Changes are made to the bike's fuel and, in some cases, ignition curves via the PC's onboard microprocessor. Using this technology we are able to offer a large area of adjustment without making any permanent changes to the bike's ECU. Removing the PC returns the bike to its previous stock condition. Each unit comes complete with software and cable link that allows you to change between different maps or make adjustments to a map file.



Multi-Function Hub


The Multi-Function Hub allows users to access advanced expansion features. Several optional harnesses are available to permit both input and output to/from the module.

Map Selection Switch
Connecting the optional Map Selection Switch allows the rider to switch between two different maps within the Power Commander. For Touring Bikes this could be used to switch between a "fuel economy map" for long rides and a "full performance map".
For Sport Bikes it could be used for applications such as "Dry Nitrous Oxide" kits to permit the user to make the fuel mixture richer when activating the system. Additionally, if the Power Commander has an Ignition Module connected it can switch to a less aggressive timing map at the same time.

Gear Position/Speed Input
Fuel and ignition timing (when using the Dynojet Ignition Module) adjustments can be made based on gear position or speed. The multi-function hub makes it possible for the user to advance the timing in lower gears while retarding it in higher gears.

Boost Input
When using a Power Commander on turbo charged applications the Boost Input option makes it possible to have the fuel automatically increase with boost level. When an adjustable boost controller is used, this capability eliminates the need for re mapping each time the boost level is changed.

Analog Output
Based on the data from the Power Commander and the inputs from the Multi-Function Hub, a solenoid, relay, warning light, etc. can be triggered. This can be used to activate items such as a shift light, Nitrous Oxide system, or air shifter.



To have your ignition curve fine tuned Dynojet recommends bringing your bike to one of our Authorized Power Commander Tuning Centers. These centers have the necessary dynamometer equipment to extract the most performance out of the Ignition Module. Click here to find the center nearest you.

On motorcycles that have eight injectors and were not previously able to benefit from the use of the Dynojet Quick Shifter, the Ignition Module now allows this functionality. The Dynojet Quick Shifter is connected to the expansion port between the Ignition Module and the PCIIIusb. For more information about the Dynojet Quick Shifter click here.

Rev X-Tend
On select models of bikes our Rev Xtend feature is available when using the Ignition Module. Rev Xtend makes it possible to increase the RPM limit from the factory setting. This feature is intended to be used on engines that have been modified to allow the increased RPM limit.


About Ignition Module

The Dynojet Ignition Module is an "add on" accessory for select Power Commander III USB. It allows you to control and adjust the ignition timing of your motorcycle's engine.
In the Power commander Control Center Software the user is able to advance or retard the ignition curve up to 10 degrees based on throttle position and RPM. It is also possible to alter the timing for each cylinder individually if necessary. The Ignition Module comes standard with no adjustments made in the map for the timing table. Due to different states of tune, fuel quality, and engine modifications we found it is best to leave the ignition timing stock for safety reasons.

The graph below represents timing adjustments with Ignition Module. The graph on right represents increased Rev Limit for certain bike models.


Dynojet offers a wide range of kits to fit any application. Several types (stages) of kits are available to fit your specific needs. Whether you run a standard motorcycle, or a tuned sportbike, Dynojet Carburetor Jet Kits can provide you with a simple and affordable solution to all your carburetion problems. Dynojet Jet Kits increase power and smoothness throughout the entire rev range, while maintaining optimum fuel economy.
