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

 

The problem isn't with the gauge...

 

uh? i don't understand..

i just want to try... it seam to be a good alternative

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

oooooooooook!

it's maybe time to buy a wideband with my friend

 

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

 

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.
