What happend to my AFR? I have an 02 WS6 and the only mods right now are LT' headers, full exhaust, innovate wideband. My question is after I got my wideband hooked up it worked fine and hovered right around 14.7AFR in MAF mode like it supposed to, but about 10 min into the run it went down into the 11's and hovered there until I stopped the run what you think this is? Thanks guys
was this a cold start??
did you start logging cold or up to full operating temperature???
are you in open loop or closed loop???
is your OLFA table still stock or set to 1.000 or to 1.131???
Do you still have catalytic converters??? do you still have COT Enabled??
My guest guess is the last one...COT(Cat Over Temp) is usually the culprit for that.

I have no cats. Everything considering fueling was stock setting at this point. Think I drove car for about 7 min. It is closed loop cause still had MAF hooked up. I don't know my guess is that it got stuck in open loop again. Cause I have the MAF off now and when I first started the tune it was like 11.5. But I think i'm starting to get the hang of the tuning. Just need to upgrade my hptuner to the EIO it's hard to compare AFR without that. Thanks guys.
