Product Overview Don’t have a dyno tuning center nearby? Are you more of a D.I.Y. (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 our Power Commander V’s. It connects to the PCV with a single cable and requires only a ground and +12 volt connection to be made to install (Harley models include connector for plugging directly into the bikes’ +12 volt line). If your exhaust does not already have one, a "weld in" O2 sensor bung is included. "Well, how does it work and what does it do for me?" We have taken virtually the same technology that our patented Tuning Link dynamometer software (for automated Dyno tuning) uses, along with Bosch Wide Band O2 sensors and miniaturized it to be used on your bike, ATV, or UTV, while you ride. 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. For Harley Davidson models we ever monitor and adjust each cylinder individually for increased precision as on these models required fueling can vary significantly between the front and rear cylinder. For advanced users that would like to change the Air/Fuel ratios from our baseline they are fully adjustable. Each throttle opening/rpm combination is individually adjustable, so that you can have both fuel economy, during cruise, while maintaining peak output at larger throttle openings. For most models of bikes it is also possible to adjust the Air/Fuel ratios "per gear". This gives you total control of the fueling in every gear and throttle/rpm area if required. The Auto Tune kit can be configured to run and correct at all times or by using the "map switch port" on the PCV. You can set it up so that you can switch back and forth between the tuning modes and the base map settings. You can also configure the Auto Tune kit to wait until the bike is at a certain operating temperature before beginning to make adjustments.
