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 they 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 their 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.
