Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Good afr?

I just got a wideband and got it hooked up and I'm showing an afr of 10.5-10.8. That means i'm running rich right? I thought a good afr was around 11.2 or so but i really don't know. Mods in sig. Thanks.
 




In the rear o2 spot on sd's I think I have a leak somewhere though. Good possiblity its the flex.
 


Does it throw it that far off having it further back? Maybe I should weld an o2 bung on the crossover and put my o2 there and put my wb where the o2 goes?
 


Yeah, having the narrow band in the cross over is fine, as long as you are not tuning off it. Wbstore and zzp both do it, and I have modded some speed daddies to have it like that seams to work fine.

Just doesn't seem super smart to me. -- Unless you have a wideband operating full time at least, even then i think it hampers the car's ability to self correct fueling. Ideal would be to have b1s1 and b2s1 but GM was too cheap for that.
