What's the best A/F meter to use?

Thanks

 

dude you really can't trust a a/f meter
i have one in my civic and it says i run pretty lean.. but yet you can smell my car runs rich.. plus when i had it plugged up to a scan tool for a check engine code... theres a engine test part in the scan tool that they did and it came back that it runs really rich... so they say never really to go by what a a/f gauge tells you..

pissed me off cause thats 50.00 something dollars down the drain... so all the darn thing does for me is makes it look cool like the car is fast or something hehe...

 

you got autometer huh

 

hehe you guessed it

 

lmao P.O.S Power:thumbup:

 

heck yea now the other day i just put some headers on and now the damn thing won't even work... i might of pulled the wire off the o2 sensor.. but still it pisses me of

and i thought autometer was a good name brand


well.... all i can say is AUTOMETER :madfawk:

 

Damn, i know they were ****ty but not that ****ty, Im going Greddy:thumbup:

Don't trust any A/F meter that runs of your stock O2 sensor, they are not reliable enough to tune. Basically all your stock O2 sensor can tell you is that your running rich, exactly stoich, or lean, not how much or to what degree. The only real O2 sensor you could reilably tune off is a broadband O2 but they're around $800-$1000 (most dyno shops have them though). Another option that will work but is also crude is an Exhaust Gas Temperature (EGT) gauge. You weld a bung and install a sensor to your header so it measure the temperature of the exhaust as it comes out of the head. If it's high, your lean, if it's low, your rich (how much is what is something you need to learn from experience, it will vary from engine to engine and location of the sensor). Only problem is, that's only good for an overall. Specific RPM tuning is basically impossible because your at a certain RPM range for a moment or two, to short of the gauge to measure. Your best bet is to find a dyno shop with a wideband O2 and tune from that. Good luck. Seeya.
