Hey guys, I was wondering if any of you guys ever tried using a unverisal BOSCH O2 sensor and replaced the OEM exhaust O2. Bosch O2 I believe is wideband and have 6 wires. What if the 2 wires are both signal wires and can be use for the computer and dedicated A/F GAUGE. Anyone ever tried that???

 

Not possible. Bosch does make a wideband O2 sensor, but you need a computer to interpret it's output - that's why widebands cost so much. You can't get just a sensor and hook it up.

Actually Bosch does make a sensor that is used with a wideband setup.

I bought my o2 sensor pretty cheap from Advanced auto, it had to be spliced in. It had 2 wires just like the stocker...

 

A wideband o2 needs to be heated to work properly and it outputs 0-5 volts, not 0-1 volts like a narrowband. Just get a narrowband o2 sensor or you'll have to buy a true wideband setup from TechEdge, FJO, etc. An A/F gauge based on the stock o2 sensor is pretty useless.
