i noticed with the more things i run in my car the more my AF guage changes....

if the car is just started and idling it will run 1green square....

if i have my lights on, stereo, foot on the brake, etc etc, it will run middle of stoich....

all depends on whats going on really....

 

irrc, the narrowband curve is like a step function, almost asymptotic in the middle, vs. the linear wideband curve, so it just seems to me that when you say it's just x amount of squares rich, that's not a particularly good indication of how rich or how not rich it is. Then again, it's been a while since I've seen those graphs and my memory may be wrong.

 

oh, well if i had a picture to show you it might help i guess....
