Simple question
Simple question that I cant seem to find a simple answer to. Can anyone tell me the difference in an AFR gauge and a Wideband AFR gauge??? Thanks.

You mean what's the difference between a narrow band and a wide band Air Fuel Ratio sensor/gauge?
The wide band is far more sensitive and therefore able to read more precise ratio's. For FI applications you want wideband to facilitate better tunes.

Sorry, Yes Huey thats exactly what i meant, I was just looking into them and noticed that they have both narrow band and wideband gauges. So I was wondering what the difference was. So the wideband is more sensitive and more precise than the narrow band correct? Also, with a wideband gauge you need to get a wideband sensor as well because the stock O2 sensor is not wideband right?

narrow band gauges are absolutely useless for air fuel monitoring.
stock front o2 sensor is wideband but it won't be able to be interfaced with aftermarket gauges.
so yes, you will need a new o2 sensor with a wideband controller and a gauge.

Alright that all makes since, so when you get the new wideband sensor with the controller and gauge does that new sensor replace the stock front sensor or the rear sensor?

if you have a midpipe with an extra o2 bung then that is that, but if you don't you will have to remove the second o2 sensor to screw in your new sensor for the gauge..
or your last option would be having another o2 bung welded in...

Ok so Huey says that it replaces the front sensor and Alz0rz says that it either replaces the rear or weld in a completely seperate bung who is right? This is the part that i really need to know, i dont want to do it wrong

^ you're welcome Mazurfer, but the pictures are typically from other savvy members here. I've amassed quite a library myself. I always like a picture to review for orientation before I dive into mod's.
^^ Again, the front O2 sensor is the one you deal with for AFR calc's. The rear sensor could actually be left off, but you'd get a CEL (unless masked by CobbAP setting).

Huey was just letting you know what they each do. I dont think he suggested to replace the front sensor. If you replace the front sensor your car will run like crap. Removing the rear will give you a CEL, but that is it. You won't pass emissions either, but once again your cars performance will not be affected.
