Our Two Cents

The Auto Tune Kit requires the installation of the “weld in” O2 sensor bung into the motorcycles exhaust because very few aftermarket exhausts come with a larger O2 sensor bung.

Product Overview by Dynojet

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. If your exhaust does not already have one, a “weld in” O2 sensor bung is included.

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 motorcycle, 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 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 motorcycles 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 Dynojet website is LOADED with information, it’s the best information resource for the Auto Tune Kit.
