DynoJet Power Commander II / III / IIIusb / III r / V
DynoJet Quick Shifters & Ignition  Module
 

What is a Power Commander II / III /IIIusb / III r     a.k.a.  (PCII / III) ?
The PC is a fuel injection and ignition timing (on some models) adjustment unit that plugs "inline" with the bikes' stock ECU. The PC uses original equipment style connectors so that 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 bikes fuel and 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 bikes' ECU (electronic control unit). Removing the PC returns the bike to its previous stock condition. The Power Commander can be ordered preprogrammed with a 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.
How Much Power Will It Give Me ?
Well that can depend upon many things but what we can tell you is "The perfect air/fuel ratio will ensure that the engine can produce the maximum possible horsepower for that given combination". We must also understand 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 shows the horsepower curve accelerating at a 40% throttle opening 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 PC installed and you can see that the line is nearly straight. So the rider will feel a large improvement while riding the motorcycle and 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).
How Can I Tune With The Power Commander ?
 

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.

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 at PowerCommander.com.  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 differences 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 no Windows 95/98/ME/XP computer and you require a special map that Dynojet has developed, UPON REQUEST AT THE TIME OF PURCHASE, ask your dealer to upload that special map in your Power Commander.  Only - $5 more for Pre-Loaded Map.  Please be sure to specify what Map you would like to be Loaded.

Face Plate Buttons

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).

                              

If you have a Windows 95/98/ME/XP computer, you can upload alternate maps or make changes to the existing map using the Control Center software and serial port link cable supplied with your PC. (Detailed Software tutorials and quick reference software screen shots are available on the CD_ROM or web-site).






How do I get 100% optimization?

First ask yourself......Is it necessary?

You installed the PC, you noticed a positive improvement and the most annoying problems like overheating, surging or pinging have been eliminated. In this state you are probably 90-95 % optimized. Which for most is a Huge Improvement.
If you desire 100% optimization or you require a custom map for a special application, you must select a Certified Dyno Tuning Center or a Local dealer that has the proper equipment and training to accomplish this for a reasonable cost and without damage to your motorcycle.

 

                               Computer Mapping

Dynojet is in the process of selecting specialized dealers throughout the country that can offer you this service. Dealers who have the proper equipment installed and pass a detailed Power Commander Training School at the Dynojet facility, will be given the distinction "Dynojet Approved Power Commander Tuning Center" and will be listed on our web-site.

Ignition

Power Commanders for some models can also control the Ignition Curve. You can adjust the ignition curve for increased part throttle response, increased peak power, or to eliminate detonation. On most models the ignition curve is close to optimum for "pump" fuel. In some cases it is possible to increase part throttle torque by adjusting the timing. With high octane racing fuel further gains can be realized at wide open throttle. Harley Davidson models, in some configurations, can benefit from a reduction in timing advance. If heavily loaded or during hot weather the PC can be adjusted to eliminate the "pinging" that is so common during these conditions.

Power Commander Versions

Power Commander II

The Power Commander II was introduced in 1999 and featured the latest surface mount electronics. Additional features were added like the faceplate button adjustment. The Power Commander II also allowed fuel and ignition adjustment on select models. The PCII utilizes "sensor offset" technology to adjust the fuel curve. Signals from the various sensors on the bike are monitored by the PCII and these signals are recalculated and sent to the ECU in order to achieve the required fuel curve.

 
   

Power Commander III

The Power Commander III was introduced in 2000 and is externally similar to the PCII. The PCIII utilizes "direct injector control" technology to control the fuel curve for models that do not possess the appropriate sensors to allow sufficient fuel adjustment using the PCII technology. The PCIII takes the injector pulse from the ECU and changes the pulse width signal to the injectors.This unit allows "Fuel Only" adjustment.

   

Power Commander IIIr

The Power Commander IIIr was introduced in November 2000 and utilizes the same "direct injector control" technology as the PCIII. The "r" version contains additional circuitry and in some cases, additional connectors, which allow Ignition adjustment as well as fuel adjustment. Ignition adjustments can provide very positive results on the race track, where factors like special fuel and highly tuned engines are used.

   

Power Commander IIIusb

   Quickshifter.gif (110118 bytes)
The Power Commander IIIusb was introduced in 2003 and utilizes the same "direct injector control" technology as the PCIII. The USB (Universal Serial Bus) port provides an instant, no-hassle way to connect the Power Commander module to a computer. This model also features an expansion port for
add-on modules like Quick Shifters, And ignition modules,   which will allow you to adjust the ignition timing.

  • Hassle free communication with new USB support
    The new 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 PCIII USB.
  • Automatic map retrieval upon connection
    As soon as you connect the PCIII USB to the computer and launch the software, the map installed in the PCIII USB will be displayed.
  • Onboard notes storage
    The PCIII 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.
  • Individual cylinder adjustment
    All PCIII USB units have a "cylinder trim" adjustment feature that allows you to "offset" fuel to one or more cylinders. Additionally, for advanced users, the PCIII USB allows individual cylinder mapping. Now each cylinder can be mapped individually throughout the entire rpm/throttle position range.
  • Enhanced "file compare" utility
    The PCIII USB software now allows you to compare two map files without the Power Commander connected. There is a numerical display as well as a brand new graphical display.
  • Easier to use "button adjustment" mode
    The button adjustment has been made easier by introducing a "startup delay". This lets the user have enough time to start the bike and then switch the PCIII USB into "button adjust" mode. The ranges of the buttons are now displayed in the software. Simply connect the unit to the computer and press one of the buttons. Their ranges are shown on the screen.
  • "Expansion port" for future upgrades and accessories
    The "expansion port" allows easy connection of  such as our new  Quick Shifters &  ignition modules, which will allow you to adjust the ignition timing
    and LCD SCREEN, and Gear Indicator .
  • 9V "Power Up" adapter
    Every PCIII USB comes with a FREE "power up" adapter which allows users to program and interface with the Power Commander on their desktop without being connected to the bike.
     
 

The new Power Commander V is the latest in engine control technology from Dynojet. The PCV is very compact, yet offers expanded features and options, with tremendous control over your engine management system.

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


OPTIONAL ACCESSORIES


 Auto Tune for Power Commander V
“Auto Tune” kits are available that include Wide Band O2 sensors and control boxes. It will plug directly into the PCV and allow automatic fuel adjustments.
Auto Tune can make a map for each gear it can map each cylinder separately for each gear if needed. (basic settings would make one map for all gears)
“Warm Up” fuel adjustment (unit reads engine temp and allows fuel/timing adjustments based on it)
Each map cell is individually adjustable so you can specify an exact AFR value for each area if needed. This allows the tuner/user to select specific AFR targets for idle, cruise, and large throttle opening areas. By doing this you can automatically tune the cruise area for best fuel economy while at the same time achieve maximum power at wide open throttle.
If Dyno Jet does not have the exact map for your combination of parts you simply need to choose the closest one and let the Auto Tune kit do the rest. (if you have an very heavily modified engine and/or short drag pipes verifying your settings on a dynamometer is recommended).
