WBO2 is off from NBO2
Guys,
Finally set my truck to run SOL on a COS5 tune. AutoVE'd to <=1% change across both VE tables.
STFT are trimming -3% and making me run lean under all closed loop.
I set NBO2s to switch at 450mV across the board.
I don't believe I have an exhaust leak- but will 100% verify in the next few days.
Is this a common issue? Any ideas?

There's no WB pid in that log file... post your calc_pids.txt (it looks like you got WB connected to EGR input).

I'm using a/c inputs.

Ok, thanks, I'll be able to take a closer look later today.

Thanks Joe. I haven't verified exhaust piping integrity but I will this afternoon.
The WB02 if wrong is making the truck too rich, so at least under boost I am safe according to both sensors. I have parked the truck though until I can come up with what to do next.
Something else worth looking at is my MAP reading. Does this seem high for the speed? My truck idles at ~60kpa which just seems very high.

I'm also loosing timing somewhere. I need to investigate more(as usual!)

Anyone have any ideas?
Exhaust pipe integrity looks great.
The NB02s are mounted in the collectors which feeds directly into a welded y-pipe where at the exit of the y is the WB02. Following that is a couple feet of a pipe and a muffler.
If any air(free 02) was entering the exhaust it would enter in front of the NB02s. So I am at a complete loss.
