o2 sensor a/f ratio and o2 voltage
can i plug my voltmeter on the o2 sensor and read it and make a table like:
0.01v = 24.90 a/f
0.10v = 15.82 a/f
0.90v = 12.40 a/f
something like that... and anybody know a real table for o2volt/af ratio ?
thanks
i am tired of my autometer A/f rice guage 
too much led, not enough precision
0.01v = 24.90 a/f
0.10v = 15.82 a/f
0.90v = 12.40 a/f

ok thanks!
so if you say: (dustin: I have a wideband, and often when my Autometer AF gauge connected to stock O2 reads full rich, my wideband reads 14.0:1. )
it is because autometer suck? Or the factory o2 sensor are good to read/change some value on the ecu on a stock car with medium performance? but it's not full precise

The factory O2 sensor is very good at detecting stoich, 14.7:1. Beyond that, it is only good at telling RICH or LEAN. It cannot accurately tell how far rich or lean it is, just that it is richer than 14.7 or leaner than 14.7

Re: o2 sensor a/f ratio and o2 voltage (TriK)
Oh and.. it"s is normal that my autometer guage glow all the rich Led when i am at WOT...
like all the yellow section glow.. after all the green...
i don"t like that..
2 led will be better than the whole section
it does that only below 2000 rpm (2led)
after that it start to (grow?) 3 led..4 led 5 led

Re: o2 sensor a/f ratio and o2 voltage (TriK)
also it is slow to react... it is useful to see if you are running lean under boost, obviously even a little "red" is no good.
