narrow band vs wind band

[djza2u1]

Can someone chime in on what the big differnace is between the 2. I know that the narrowband uses the current 02 sensor and that the windband uses a new sensor. I currently have a narrowband and wanted to know the benifits of switching to a windband.

It's spelled wideband, the wideband is 100's times more accurate/faster.
The narrowband is pretty much a light show, get the wideband.
I have a AEM Uego Wideband in my turboed 3, a must have for tuning.

Wideband is a much more accurate air/fuel ratio reading. The narrow band uses the same info that the ecu does for keeping stuff running right. For those purposes the info is fine but for tuning, it is useless which is what you get with the narrowband. Like the guy above me said, get the wideband. You won't regret it.

The MS3 has both.

The wideband is the primary O2 sensor used to maintain correct A/F ratio and the narrowband is used to measure catalyst efficiency.

One is not more accurate than the other (and certainly not faster). They have different functions.

If not mistaken a Narrowband reads 1 time per second, While Wideband reads 6 times in a seconds being more accurate perfect for tunning and running EMS Well worth the money if you ask me, Same if you add a EGT gauge as well..

the samples/second depend on what is reading it.

A wideband is usefull for tuning, for seeing the entire fuel range from very rich to very lean. A narrow band is best in the ranges between 13.0 to 15.0 and is used specifically for the ECU to run as close to stoichiometric as possible.
