Wideband o2

[AWDLATIN]

Ok, I have been doing some searches, and none have answered my question. How does one operate a wideband? Where does it connect to (I am guessing the ECU and o2 sensor)? How do the o2's volts correlate with the A/F meassurements (11.5:1) What do those numbers mean? I am really getting tired of all the pulled timing I am getting, so I need to know a bit more in order to fix it.

Thanks guys

You can still tune without a Wideband. People have been doing it for years. Do you have a logger of anysort?

a wideband hooks up to a 12v power source and ground. It works off of a specific o2 sensor, not your stock one. Essentially thats it, you install another o2 sensor and the wideband gets its reading from that.
