The screws and nuts that hold the Air-box Cover on have a habit of jumping out of the air-box and running away. No idea where they go, but it is far! These cannot be purchased separately from Suzuki but we found some that are perfect replacements. This little kit includes four screws and the square nuts that go into the air-box. We recommend that you put a dab of silicone or something to hold the nuts in so they don't jump ship like the other ones did.

Don't have a dyno tuning center nearby? Are you more of a do it yourself type? Are you constantly changing parts on your bike?

If you answer "yes" to any or all of the questions above, then our Auto Tune kit is for you. The Dynojet Auto Tune kit is an "add on" accessory that can be used with any of the Power Commander Vs

It connects to the PCV with a single cable and requires only a ground and +12 volt connection to be made to install. If your exhaust does not already have one, a "weld in" O2 sensor bung is included

Once installed, the Auto Tune kit monitors the fuel mixture (by installing the included Wide Band O2 sensor in the exhaust). It then sends this information to the Power Commander V and automatically corrects it while you ride. Each map that we offer has preset Air/Fuel ratio values included that we find to be the best overall settings. This lets you simply plug in the unit and let it do the work.

Two-position map-switching is capable with this Single Pole, Single Throw switch. You can toggle between two different fuel maps quickly and easily.

For Use with the DynoJet Power Commander V

Dyno and field tested, the Power Surge 6X will allow correction for humidity, temperature, air pressure, along with race fuels and motor modifications. The tuner adjusts in a matter of seconds in 6 zones, including an accelerator pump feature for more throttle snap response. The tuner can add or subtract fuel from the injection system. Conditions like rich or lean running, and stalling from flame-out at low revs can be corrected.

The perfect tuner for users who are always on the move, the Power Vision 3 allows you to tap into more horsepower and optimize overall performance by quickly and easily flashing your ECU from anywhere.

• Easy-to-read, no-nonsense display puts performance at your fingertips

Power Commander Fuel Controller (PCFC) Product Introduction

Inexpensive yet very precise way to control your fuel curve.

The Power Commander FC is a plug-n-play fuel management device pre-programmed with Make/ Model specific maps. In addition the Power Commander FC has the added ability to modify or change these maps on the fly without a computer.

Users can literally select between a Power Commander FC Map, custom-built maps, or even fine tune low, mid or high rpm ranges while sitting on the bike and without plugging into a computer. Standard +/- 15% increments from selected map settings, different ranges are available using the supplied Control Center software.

Users can also load up to 10 of their personally built Power Maps into the Power Commander FC and select between them while in the saddle - eliminating the need to "re-boot" with the computer every time a new map is desired.

PCFC Features:

• Uses OEM style connectors and high quality wiring harnesses
• Small, lightweight and easy-to-fit on the bike
• Pre-programmed with PCFC Power Maps specific to make, model
• No computer necessary for modifying fuel management
• Fully adjustable computer compatibility for ultimate tuning and personalization

Most fuel injected systems are very lean in their stock configuration. This is good for economy and emissions, but not performance. This unit allows you to adjust the Fuel/Air (F/A) ratio without remapping the ECU and getting into complicated software programs. The PowerJet Fuel Controller allows you to adjust the fuel map from -4% to +10% by selecting one of 10 built-in settings (including stock).

The device works by measuring the outside air temperature very close to where the stock sensor is located and then adjusts the signal from the OEM air temperature sensor to the ECU to make use of the Air Temperature Correction factor that is built into the stock ECU. The ECU is told that the intake air is a little cooler than it actually is and it responds by richening the injection map very slightly. How much depends on your setting on the PowerJet. This will result in improved throttle response, especially if you have an aftermarket exhaust of any kind.

PowerJet is easily installed by plugging it in between the stock AIT sensor and the bike's wiring harness under the seat. This can be done very quickly as they are exactly the same plugs. Unplug the stock connection, plug in the PowerJet on each side. The PowerJet fits easily under the seat behind the battery as it is rugged and waterproof. PowerJet comes with a full one year warranty.

We also include new low friction cables, an extended fuel screw, complete instructions along with a wide range of extra jetting for fine tuning. It even has a vacuum port for the stock fuel petcock.

The carburetor comes pre-jetted for the typical mods: performance pipe and modified air box, or we can set it up for your particular bike before we ship it out.
