Dynojet Triumph Daytona 650 Power Commander III USB 2005 - PC3 USB Motorcycle Fuel Tuning + Adjustment. Graves Motorsports is the leading resource for motorycle Dynojet Fuel Computers for your sport bike, cruiser, off road (dirt bike or atv) and snowmobile. 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 Power Commander III USB 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. Graves Motorsports will program your purchased power commander with a map free of charge when purchased (specify in notes at the time of order your bike's setup).
Use the pull down menu to select your make, model and year power sports vehicles. Graves Motorsports offers Sport Bike, Cruiser, ATV, UTV and Snowmobile Power Commanders from this listing!
Power Commander Map Database
Dynojet supports the Power Commander product line with the worlds largest map database. Graves Motorsports specializes in custom maps for our performance exhaust systems. Dynojet also works with the leading exhaust manufacturers from around the globe to bring you maps with 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.
Features
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 PCIII USB.
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 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 upgrades and accessories - The "expansion port" allows easy connection of accessories such as our new ignition module, Quick shifter, Multifunction Hub, Pressure Sensor display and LCD display unit. 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.
9V "Power Up" adapter - Every PCIII USB comes with a "power up" adapter which allows users to program and interface with the Power Commander on their desktop without being connected to the bike. Accelerator Pump - You can adjust: A) The amount of fuel to add, B) The number of engine revolutions during which fuel is added, C) The sensitivity of throttle movement under which the accelerator pump is activated.
How much additional power will it give my motorcycle?
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).
Tuning with 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
