I was screwing around doing some logging today and
I logged AFR "without a wideband" is this possible?

at wot AFR showed 11 and the O2's were 910-920

is this too rich and
could this explain how I get 39* timing at wot
with no knock?

should I try to lean it out a little and then adjust timing
so theres no KR?

If 890 is the # to shoot for then what number above or below
890 should be cause for concern?

I plan on taking it to a dyno with wideband in the future
when I understand this tuning a little more.
