i have the aem uego wideband. its cheap and simple to use.

What should I expect to spend on a aem uego wideband a/f meter? I searched ebay and found them for $250-350. Could I just use my o2 sensor signal instead of getting meters with the bosch sensor included? Thanks



no you cant use your old o2 sensor. the gauges the use the stock o2 sensor are pretty much useless for air to fuel ratio monitoring. all they can tell you is if the car is stoich or not stoich, witch wont do you any good. a wideband comes with its own o2 sensor that can read you exact air to fuel ratio.

there is a big difference between an a/f gauge and a wideband.
