So just a random question but why are narrowband gauges so bad? I mean really stores sell so many of them and there are tons of them out there but how come like a air fuel ratio one just doesnt read how it should and what not/

 

I've never heard of narrowband

 

Makes sence that there would be one, otherwise the phrase "Wideband" would be dumb, and it would just be called an AFR gauge.

 

voltage. Narrowband reads a 1 volt sweep while a wideband reads a 5 volt sweep. 5 volt sweep is a lot more accurate.

 

this. narrowbands are useless.

 

I agree. I mean people buy the damm things but i find them to be useless but they sure are priced better. But to each there own i suppose

 

of course they're priced better cause they're junk, you get a bar that says lean or rich LOL. narrowband is some ricer ****.

 

Narrow band is for show. Wideband is for accurate reading that will give u a real time accurate reading

 

That is very true indeed. Make a very nice light show

 

Also note that a "Narrowband" O2 sensor doesn't provide an accurate reading at wide open throttle and is promptly ignored by the ECM.

A wideband O2 sensor provides accurate readings at all times.
