No matter what modifications you’ve made or the elevation you ride in, the AutoTune Module is the accessory that brings it all together. Made especially for Harley-Davidson motorcycles, this connects to the bike’s diagnostic port through a 4-pin connector. This module is designed to be used in conjunction with the Power Commander V fuel tuner for your Harley.

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.
