A regular O2 is the stock sensor that helps the CPU determin the air fuel ratio by telling the CPU if the exhuast mixture is lean or rich and keeps the mixture at an ideal level . Wide band O2 Sensors usually give a ratio reading like 10:1 idel is like 12:1 go any higher than that and you run the risk of a lean misfire (serious engine damage) can result. You can basicly tune the car with the right equipment and a wide band O2

A standard 02 sensor will tell if the car is at 14.7:1 (stoich, aka ideal air/fuel for economy,) below 14.7:1, or above 14.7:1. It will not give accurate readings in either direction.
A wideband O2 sensor will give a voltage reading accurate enough to give an exact air/fuel reading to tune off of.
Example: An engine is running an air/fuel ratio of 12.0:1
A narrow band "regular" 02 sensor will put out a voltage saying the car is running below 14.7:1.
A wideband will output a voltage saying the car is running 12.0:1.
This accuracy difference is why wideband O2 sensors are so much more expensive then standard narrowband O2's.

The wideband uses a volt range of 0-5 volts to determine air/fuel mixture, whereas, the stock O2 sensor uses 0-1 volts, so you can tell what is more accurate. The narrowband output is meant for the computer to decipher, not the driver, so trying to tune from it is impossible since the computer has already made fueling changes when you read what the narrowband a/f ratio meter says at that particular RPM.

Matte is more of a texture, how something feels, like a rough surface... Gloss and semi-gloss are finish, basically how a surface looks... I had it mixed up basically...
