Well that data shows essentially the same as post #30 above. Both O2 sensors are switching, although Bank-B voltage range is lower than Bank-A. My understanding is this shows the air-fuel ratios are adjusting more on Bank-A, but not sure which side is better ! Did you try swapping them over yet ?
Defintely check for air-leaks all the way from the MAF to the throttle body & manifold. Also check the exhaust manifolds are sealing against the block and the joints ewither side of the Cats.
Do a recording for the Air Fueling menu as well, so we can see the MAF airflow data at various points in the rev range.

The rest of the Nanocom data seems to be fairly useless because none of the values change throughout. Not sure why column-U shows O2 Sensor Not Set, because they are clearly switching ??
From your file, it appears the Nanocom recordings for Motronic do not include other useful sensor data. It might need a different diag reader that can select the useful values & ignore the
crap stuff that doesn't change !

FYI I have posted a question on the Nanocom Forums to see if it's possible to combine fuel & air data recordings.
