Is an Air/ fuel gauge useful on a car that does not have a wideband O2 sensor?
Would it work precisly?
Already searched and didn't find good info. Please share your thoughts.
Thanks

 

without a wideband, I would say it's just eye-candy.

 

have you ever seen one in action on a car that doesn't have a Wideband.
Do you know that for a fact.

 

just my opinion, havent seen it first hand

 

kool, thanks anyways. Do you have any idea how much a wideband O2 goes for?

 

brand new, roughly ~$300 and up

 

WoW, And thats US $$ . ****,

Thanks bro.
I rathe rtune the car at a dyno that provides wideband sensor.

 

I bought one and, yes, it's just eye candy. It's coming out in one week in exchange for Defi bling.

PLX makes some good looking wideband monitors.

I have. I bought one years ago when I thought they were useful. Then I realized they werent.
They do absolutely nothing without a wideband.
I have had both in at the same time on my ITR and yes they read different.

 

I temporarily hooked up an A/F gauge to my ITR and it was useless...holding dead steady revs anywhere in the rev band and the leds jumped all over the place from rich to lean. It looked good at night but i took it out as it was just distracting.

 

thanks everyone.

 

It is only really useful if you got major tuning N/A, boost, or nitrous. It will let you know where you are running at full throttle, You dont want to be boosting or spraying and your motor leans out. You can moniter that with the A/F guage. About 85% of people just put it on to look good
