The OXS measures the extra oxygen in the exhaust. When you are lean you get a low reading like .1 or .2. at cruise or idle or anything where the closed loop stuff is happening it should be around .5. At WOT it should be richer giving .7, .8, .9 something like that. I know for a fact that the turbo Dodge people tune them to run at .9v at WOT. .1= lean .9= rich
