Power Commander III USB for Yamaha YZF-R1

Power Commander III USB Product Introduction 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. Power Commander Map Database 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. Read Full Description 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 additional accessories - The "expansion port" allows easy connection of accessories such as our Ignition Module, Quick shifter, and Multifunction Hub. 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. Additional Features for Harley Davidson - The first new feature is "Rev X-tend". This will give you the 88 power-vision-cx-promotion Power Vision CX Promotion
