No matter what modifications you’ve made or the elevation you ride in, the AutoTune Module is the PCV accessory that brings it all together. This module is designed to be used in conjunction with the Power Commander V Fuel Tuner. Once installed, the AutoTune kit monitors the air/fuel ratio. It then sends this information to the Power Commander V 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.
