The Dynojet PCIII USB plugs into your stock wiring harness, allowing you to alter your stock fuel injection maps +/- 100% over stock. It can be used to smooth out power delivery and eliminate flat spots on bone-stock motorcycles, as well as extract power and rideability from bikes that have modified with aftermarket exhausts, air filters, or engine mods. Stock maps are not altered, and simple removing the unit reverts the motorcycle back to stock configuration. Dynojet Power Commanders are arguably the most popular tool used today to effectively tune fuel injected motorcycles.

• Plugs directly into OEM wiring harness using stock connectors. Can be removed in minutes.
• Does not alter your ECU or any other part of your system in any way.
• Allows for an incredibly fine degree of tuning... much more than most competing products.
• Cylinder trim adjustment provides the means to tune each cylinder individually!
• Connects to your Windows-based laptop or PC via a simple USB connection.
• Included software allows you to upload, download, view, edit, and compare map files.
• Fuel adjustments can either be made by altering map files, or with easy-to-use buttons on the unit itself.
• Expansion port allows for modular integration of other Dynojet hardware, such as quickshifters, ignition modules, and LCD displays.
• Includes an extensive collection of fuel maps covering the more popular combinations of aftermarket mods.
• Comes packaged with a 9-volt power adapter (for use off-the-bike), USB cable, software on CD-ROM, and user manual.
• Supported and endorsed by more dyno facilities than any other system. Custom maps offer the ultimate in performance.

Use the option box to select between either the standard or EX version. The 'EX' model was developed specifically to meet California C.A.R.B emissions requirements. If you don't live in California, or your motorcycle is used for track use only, we recommend choosing the standard version. EX versions cannot be used with the Dynojet ignition module or mult-function hub (where applicable).

As an added bonus, we'll load your PCIII USB with the best dynojet-supplied map for your application prior to shipping. All you have to do is list any aftermarket modifications you've made to the engine, if any, in the 'additional comments' box during checkout. In most cases, this boils down to what type of exhaust system you're running and if you're using an aftermarket air filter. Any engine modifications should likewise be noted.
