Posting hear also for wider distribution:
What would the norm be for these numbers? Using FAST b2b , Listed Below are my#'s.
UEGO (V) 5.00
UEGOS (V) .31
UEGOR (V) 1.69
My (A/F ratio) locks on (15.94) and does'nt move! but the (O2 correction) does! it correct's! In the (temperature correction- CTS) table I moved the enrichment up 50% and the A/F never changed. but the wierd thing about it is, it smells like it's pig rich! even back at the orriginal setting.

To amplify Scot's post a little, I was over trying to help out today, and even though I'm not FAST expert, there were some things I saw that were a little strange.
On the FAST dashboard:
System is locked on an A/F ratio readout of 15.9, even thought the car smells a little on the rich side.
When reving the engine and getting it up into the closed loop minimums you can see a changing "A/F correction" value.
When reving, the UEGOS (V) value does change a little from .31 to about .27 I have no clue what that value is.
UEGO (V) 5.00 I assume is the operating voltage, but can't swear to that. It also never changes.
The voltage I am most suspect is UEGOR (V) 1.69 Again, I'm only guessing, but it's my suspision that voltage indicates the sensors's output value. The reason I say this is because in my mind's eye, I can see where 1.69 plotted along a 0-5 line might equate to an A/F ratio of something in the 15.9 range.
I suspect a bad O2 sensor... Can anyone verify based on the above info????
