About Oxygen Sensors (narrow and wideband)

What is the difference between a narrowband O2 sensor and a wideband?

Why everybody says a wideband its a lot better and a good improvement?

i dont really feel like going in depth on the subject , but,

narrowbands are only accurate from around 14:1 to 15:1. narrowband reads 0 -1 volts. the higher the voltage, the richer the readings. widebands can read up to 5v........................so whats the point?

well, if you can read higher voltages, you can get more accurate readings, not to mention, richer readings. when you are boosting or need to change AFRs due to increase in air volume, typical AFR targets are in the 12:1 (not always true, but, you get the pont) range when boosting (hence the need for the wideband).

also, widebands need to be used with a controller. digital displays are more user friendly and makes life easier when you are on the dyno and changing AFRs in real time. its not that a wideband is better than a narrowband. you just dont need a wideband o2 sensor when you are running on a stock setup.
