Default Has anyone ever seen this?

Logging my friends car, went to view it using excel and notice the O2 B2 is copied in different areas to the LTFT B1 and sometimes B2. I have never seen this before. Looking at the logs cause the car ends up running like crap 2-3 days after being tuned. I figure it has to be from either junk O2s, or the fact the PCM was never flashed back to stock after using Predator. Looking at this, I can see why the car would start acting up. Logs from 2 days ago were fine, everything worked fine as well, now after day 3 and 4 the car runs like dookie and the logs are jacked. Has anyone ever seen this before?

This car has had three edit files input.
1) went back to popping at the top end, and idle like dookie after 3-4 days.

2nd) was good, no problems after 2weeks, so tried to adjust the idle when cold and decay rates etc... creating

3rd) current, went from idle smooth, start right up, and pull hard almost 0 KR, to popping on the top, idle like dookie and such on days 3 and worse since day 4!

WTF?

Charlie.
