These o2 readings look ok given my combo?
My o2's were definitely hosed before. I found an issue with the heater circuit and got that resolved. Heres two pics of a scan and im curious if you guys think they look ok? They will only switch when I rev the motor past idle. When I return to idle, they stop switching. Details of my combo:
LS7 12:1 CR
TFS 245's
230 @ .050'ish .660'ish lift 110 LSA
Full length headers with o2 bungs in the merge collectors.
These are fairly new Denso o2's. Thanks in advance!

Looks like there's too much fuel at idle.
Looks like the HO2 voltages swing too slowly at part throttle.
Is your wideband working, because it looks wrong.
Your images don't show LTFT's.

Yeah, this is quite possible.
This is what I was worried about.
It was disconnected when I ran that scan.
Yeah I was currently using a work in progress idle tuning config.
I appreciate your reply. At this point I am really leaning towards throwing the 02's in the trash and going OLSD.
