    wide band

    I have installed a wide band setup om my 99 ta and the monitor says its 14.1-15.5 up an down at an idle but it smells rich like it should be 9-12. is it normal to be around 14ish at an idle? wot is 12.3-13 what about that?

    It should toggle either side of 14.7 after the engine is warmed up and in closed loop. 12.3 to 13.0 isn't bad but you need to use a dyno or 1/4 mile times to tell how your doing at WOT.

    If you have no cats, significant camshaft overlap, or both, it's gonna smell. That's why we use a wideband and not our nose to tune

    WOT.... with no dyno, I target 12.8 on the street for most N/A applications.
