AFR reading...... All hooked up and first "test" drive around the block with Daughter at the laptop recording.
NO full tilt blasts but did get on it some. After a cruise around the block, up to temp, at idle it was upper 12's to very low 13's.
I tried to watch as I was on the gas at cruise...very jumpy
I guess that's the way it is.
Anywho............WHAT should it read or I look for ????

My O2 is fairly jumpy as well. dont get too carried away with every .1 change, just watch the overall.
My stuff always idled best around 13 - 13.5:1
I would pay attention as I stepped into throttle to see what the shooters/cams were doing for accell enrichment - mine worked best when I see a VERY momentary rich spike to about 11.8 - 12.5 during throttle transitions.
cruise I liked anywhere in the 13 -14 range, but my cruise A/F's always seemed to be slightly rich arouns 13.2 as I was not overly concerned with perfecting it, and my idle mix screws effected it alot. best idle setting, seemed to richened up my cruise equally. I guess it was cruising on the idle circuit.
I ran my WOT A/F's between 12.8 - 13.2, It seemed to run much the same no matter where it fell in that range. the last tuneup I ran was at 13.2:1 WOT
