Default O2 Sensor Variance in VCM Scanner?

OOOPS POSTED IN WRONG AREA. I REPOSTED IN TUNING FORUM. THX!


I built my new 6.0L motor and am tuning it now. It's running like a top but I'm running open loop to dial in MAP sensor right now. Haven't done much closed loop driving. During my data logging I've noticed something weird with the O2 sensors. I put in new O2 sensors assuming it was a sensor issue but doesn't seem to have changed much.

Below is a waveform of what I'm noticing (I've also attached the tune file and data log). Bank 2 seems to fall out of agreement with Bank 1. It will do this for a while then match up again. Not sure what that is or if is normal.
