What do you guys think about a digital type a/f gauge that displays the o2 sensor volts, vs the typical bar graph type like from Autometer.
Which one would be more accurate?? I would think the digi type would be since the Auto Meter type bounce all over the place.

Screw 'em both IMO. Narrowband and accurate don't belong in the same sentence. If you really want accurate information on the air fuel ratio get a wide band.
I have a greddy A/F warning guage. they're expensive But i think it's worth every penny.

U could use a wide broud band 02 sensor from old honda engienes. Engines with the miller cycle used to run on lean AFR. Those o2 sensor are more far acurete and has a wider scale.
the guage has nothing to do with it... that is just a matter of preference... what matters is wideband or narrowband.
I know that meater has nothing to do but if u want to measure AFR wiser would be to use a wideband o2 sensor. Its more acurate and have a larger scale. on normal max rich ratio is something like 12.5/1 and u know nothing that is above.
