Bob has a Harley on the rack that already has a custom exhaust and air intake installed. The motorcycle is not performing well because the ECM / EFI was not remapped. Bob removes saddlebags and side cover so we can see the ECM. He removes the ECM connects the Power Commander to it with a little dielectric grease and re-installs the ECM. Keep everything tie wrapped so it stays in place. He tunes the ECM by mapping the Power Commander on the computer. There can be many maps for your motorcycle set-up. It’s easy to try one and test till you find the right one.
