The DynaTune kit monitors the fuel mixture (by installing the included Wide Band O2 sensor(s) in the exhaust). It then sends this information to the Dynatek Fusion Control Module and automatically corrects it as you ride, letting you feel the changes as they happen. Each map that we offer has preset Air/Fuel ratio target 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 who 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”. make adjustments. This gives you total control of the fueling in every gear and throttle/ rpm area if required. The DynaTune kit can be configured to run and make adjustments at all times or by using the “map switch port” on the Dynatek Control Module you can set it up so that you can switch back and forth between the tuning mode and the base map settings. You can also configure the DynaTune kit to wait until the bike is at a certain operating temperature before beginning to make adjustments.
