i only have a narrow band autometer A/F, but it shows i'm lean when i'm cruising at 1000-1500 if i get on it i'm rich. at an idle it's back and forth and back and forth. how do i adjust that?

You can't. On device only allows for WOT air/fuel changes if that option has been enabled. If you have a custom tune and need part throttle air/fuel adjustments you will have to have whomever made the custom file do it for you.

A narrow band gauge is pretty much just a light show though so most likely you are not running lean.
