O2 Correction for FAST-WP

[BigBird R/T]

Noticed my O2 correction not working "sometimes" when doing a dyno last week and wondering if an O2 going bad could still show A/F and not do any corrections?

if its dirreclty after start up it is possible there is still sfter start correction in play.
Add aft cor to you dash and make sure it says 0 before you start to dyno.

I "assumed" I had all the asc's in range but now you got me wondering.........
One time during one pull it quit correcting half way through the pull. That's what really had me puzzled.
Will put that cell on the dash board for the logs and monitor it.
Thanks

It can also be possible it wasnt correcting at that point and was tuned right on
