wondering about my 02's log attached

[Gregs]

I just wanted to get a second opinion on my bank 2 sensor. It doesn't switch back and forth it just stays right around 450 mv. At the same time my stft for bank 2 is pegged out at 99%. The thing that I don't get is why my bank 2 ltfts are perfect. What do you guys think?

just giving this a little bump, but since my first post i have swapped out o2 sensors a few times with other ones i have laying around and i still have the same problem. Its as if the sensor just isn't switching back and forth no matter what o2 sensor i have in there. anyone have any theories?

Thought I would help your bump...

Are you logging both O2's on the same bank? I usually log just the front O2's of each bank.

Our set-up is probably quite different, but was just trying to understand what you were doing..

You might be logging the wrong pids...

replace O2Sxx with SHRTFT1/2.

Played log in "data" format, couldn't see it well enough in the "dashboard B" format ... no O2 voltage from either bank, no short term fuel trim from either bank.
