You will never get your 02s to "settle". They're meant to oscillate. Actually, the fuel trims are meant to oscillate, and the 02s reflect that.
Catalytic converters need alternating rich lean rich lean to supply the catalyst bed with alternating (high, low) levels of oxygen as well as hydrocarbons.
You're long terms are very negative.
I haven't looked at the tune yet.
