are these a bad idea to install?
i have a chance to get a cobalt guage for 15$.
will it work on my 95's o2 sensor?

Absolutely 100% useless. It will not tell you your A/F ratio and it will not let you know if you're rich / lean at WOT.

Sams right. A wideband gauge is what you need if you plan to know for sure what you have, or plan to tune by it. A narrow band is just for the pretty light show.

why do they even make narrowband a/f gauges haha

samseed101

For the same reason they make neon lights, fart can exhaust, large spoilers, fake nitrous purge kits, the turbonator, electric superchargers, etc.

haha just for show... and another way to make money

wideband or nothing

aem wideband guage and sensor, you can see your a/f ratio w/ the guage and hook the tweecer up and see it in there also with ur datalog.

btw sam do you kno how to make the adjustments so that tweecer sees the same a/f ratio as ur wideband, i kno through wire resistance the #'s change. i have the aem guage and it has a bosch sensor.

I'm dealing with the same problem. You have to get a wideband transfer curve for that AEM.
Then load that curve to Cal Con. Good luck trying to find the transfer curve. If you find one
let me know. But open Cal Con , click the setup tab, under the EVP signal transfer click AEM or
PLX thats what I use. then in the second window click AFR.
