Check out this atap log, my B2S1 is whacked. This is a 1/4 pass and my O2 readings on bank 2 is reading way to lean causing 3+ of Knock. My car is running a few MPH slower because of this. If I richen up the WOT setting so B2S1 is right, then my B1S1 reads .960-.980. I even swapped the rear O2 with the front and got the same readings. So what parts on the car could cause bank 2 go so lean? I was thinking maybe the injectors are a little clogged on the passenger side. Suggestions?

Re: Check out this atap log, my B2S1 is whacked. Possibly an exhaust leak on passenger side introducing fresh air into the system before the O2 sensor such as where the exhaust manifold mates to the cylinder head? Do you have headers?

Re: Check out this atap log, my B2S1 is whacked. I looked at your trace, it's really too short and not covering all I would want to concrete what the calibration is but her is what I see:
Report findings
It has 3 sheets, data, graph and results.
The parameters empty are cause they were not recorded and injector size of course is not yours since I do not know what they are.
LTFTs are about equal, but if you would monitor inj pulse width and misfire I could tell more but I would look for a exhaust leak, but also if you would look at the S2 O2s a compare could be done.
I trace with the parameters I show blank in data sheet would help pin down better what is going on.
