The wideband O2s typically require a special closed loop controller, such as the LM1 from innovate, to regulate the temperature of the sensor, and have a much broader range of output. Theyre what youd use for tuning the engine.
The stock narrowband sensor just goes to around .9V above 14.7 and 0-.100V below 14.7, and just tells the computer if teh engine is above or below stoich. The best sensor for the car is probably a standard heated delco O2.

I agree 100%. Stay away from Bosch 02 sensors as they tend to make a stock tune run slightly rich. Stick with plain jain AC delco. Around here most parts stores only sell Bosch so I am forced to go to the dealer to order them.
