The Dynojet Power Commander plugs inline with your bike’s stock fuel injection system. It uses OEM (original equipment manufacturer) style connectors making installation easy and quick. The PCIIIusb allows a full range of fuel adjustment, as much as +/- 100% over stock. Adjustments can be made either with a Windows based computer or by using the face plate mounted button adjusters. No permanent changes are made to the bike’s system. Once the unit is removed the bike reverts to its stock settings. Dynojet supports the Power Commander product line with the worlds largest map database. We work with all of the leading exhaust manufacturers from around the globe to bring you pre-tested settings for your motorcycle. No guesswork on your part. Every map that we offer was tested and developed on one of our multiple in house Dynojet Dynamometers using our patented Tuning Link software. New maps are developed weekly for all popular applications. For custom or specialty applications where it is not possible for us to have a map available, there is a network of Official Dynojet Tuning Centers. These facilities have the required equipment and training to develop custom maps for your vehicle.

Hassle free USB communication - The Power Commander USB will instantly and automatically connect to the Power Commander Control Center software once it is installed. Simply "power up" the unit and connect the supplied USB cable to the computer and PCV USB.

Reduced size from PCIIIusb (less than half of the size of PCIII) USB powered from computer (9 volt adapter is no longer needed for programming) 10 throttle position columns (up from 9 on PCIIIusb) Enhanced “accel pump” utility (increased adjustment and sensitivity ranges) .

2 position map switching function built in (map switch not included)
 

Gear/Speed input (allows for map adjustment based on gear and speed)

"Analog input (allows user to install any 0-5 volt sensor and build an adjustment table based on its input such as boost or temperature)


Analog input (allows user to install any 0-5 volt sensor and build an adjustment table based on its input such as boost or temperature)

With gear position input connected the PCV is capable of allowing each cylinder to be mapped individually and for each gear (for example: on a 4 cylinder bike with a six speed transmission there could be up to 24 separate fuel tables).
 

Unit has a -100/+250% fuel change range (up from -100/+100%). This allows more adjustment range for 8 injector sport bikes

Onboard notes storage - The PCV USB stores the notes from the map in the onboard memory. This makes it easy to see exactly which map is loaded. The notes, just as the map itself, are automatically retrieved upon connecting to the unit.

Dynojet Research is pleased to announce two new features for the Harley Davidson Power Commanders.

• Fuel and Timing control
• Rev Xtend
• “Warm Up” fuel adjustment (unit reads engine temp and allows fuel/timing adjustments based on it)
• Software will display J1850 data from bikes’ stock ECU (this is data such as temp, fuel pulse width, timing advance, spark knock, etc.)

There are many variables to each application. The Power Commander allows for tuning to the perfect air/fuel ratio will ensure that the engine can produce the maximum possible horsepower for that given combination.

Consider that a typical street rider spends a great deal of time riding in part throttle conditions. Shown below are two graphs of a motorcycle before and after installation of the Power Commander. The top graph line shows the horsepower curve accelerating and 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 that same combination with the Power Commander installed and you can see that the line is nearly straight. Consequently, the rider will feel a large improvement while riding the motorcycle. It is very possible that the peak wide open throttle horsepower is unchanged. The correct air/fuel ratio number (say 12.9:1 or 13.2:1) depends upon many factors like combustion chamber design, but what we want is that figure at every point in the curve (straight line).

Base Map - The Power Commander is supplied with a given (base) map stored in the microprocessor. This (base map) is typically a map that has been developed to provide an improvement for most combinations matching the map description (i.e. stock bike or performance exhaust and air filter).

In general we have found that a typical stock bike has areas in the fuel curve that are far from optimal for drive-ability and performance. We could say that they are typically 70% optimized in stock condition and 60% - 65% with minor performance modifications. After installation of the Power Commander with the base map, we would expect to see 85% - 95% optimization. Power Commander Alternate Maps - Each Power Commander is supplied with a number of alternate maps on a CD-ROM and all the maps are available for download on our web site.

You may notice that we have a map specifically for "Brand A" slip-on exhaust and another for "Brand B" slip-on exhaust. Although the difference between the two maps is likely to be very small, these difference will increase the optimization for that given combination. If you have a "Brand C" exhaust and we do not have a specific map, you should find that "Brand A" or Brand B" maps will provide a good improvement on your bike.

If you have a Windows 98SE/ME/2000/XP computer, you can upload alternate maps or make changes to the existing map using the Control Center software and USB cable supplied with your PC. (Detailed Software tutorials and quick reference software screen shots are available on the CD-ROM or web site).

If you do not have a computer, you can change the fuel curve with the faceplate buttons. This is a simple adjustment that can move the fuel curve richer or leaner in each area of the map. (Please refer to the paper installation guide or adjustment video on the CD-ROM).
