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.
"Well, how does it work and what does it do for me?" Dynojet has taken virtually the same technology that their 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 KTM models it will 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 the 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.
All 990 LC8 engine and Rc8 bikes come with the proper 18mm O2 bung threads for the wide band O2's included in this kit. All modern KTM motorcycles since 2014 contain 12mm threaded bungs and will require welding included 18mm bungs to the header. For much nicer bungs, see here. If you have a KTM Adventure 1050 through 1290, see our custom Arrow header here complete with 18mm bungs already installed if you were considering this already.

  1. Great tuning aid. 4 Star Review

    Great for getting every drop of power from your bike while tuning for fuel economy and around town performance.

  2. Saved so much $$ in dyno time 5 Star Review

    I am glad I took advice from Chris on day one to fit the AT300 in addition to the PCV. Each time I have changed a part in my engine/fuel/exhaust setup I have been able to change my tune without a visit to the dyno. It also lets me setup maps for max power, economy and hybrids of both which can be changed on the fly with a switch. Took the bike for a dyno session recently and the tech concluded there was nothing to do as the tune was good to go. Very happy with the AT300 and I use it all the time.
