I have a wideband installed. street ported engine with stock fuel system and all emmissions removed. did retain the bac for idle purposes. I am reading 12.4-12.9 at idle and 760 rpm. Cruiseing I am any where from 11.9 to14.9 b ut with foot barely on throttle ussually 13 ish. do these numbers look normal. Any imput would be greatly apreciated. Sorry fo the spelling

 

Yes, they sound normal.

 

 

Thanks

 

So where did ARGH get these pages from? What manual and is it online? Thank you.

The 122*F figure caught my eye because each day when I start and drive the car cold, around 120*F is when the afr goes from rich to almost normal afr. Like takes a step up from 12afr to 13 afr in general.
