Is it possible to use one wideband sensor and eliminate the 02 sensor or welding another bung a must in order to have both.

 

My plx wideband has an output for the narrowband. I had just been using the stock one, but now that the wire on it broke, im just going to tie the wideband into narrow band on my ecu. The stoke narrow band will basicly just be a plug.

As far as a second bung, most companies recomend that you stick the wideband down range a bit from the turbo. Mine is mounted about 20inches back. When I put a wideband in my vert, im going to just mount it in the stock o2 hole and tie it in to the ecu for narrow. I'm pretty sure it will shorten the life of the sensor but i'll keep a good eye on it, just in case.

So the ansewer to your question is yes.

 

So you can use the plx wideband sensor for both 02 and wideband, thats great to know. Also, Is PLX the only one that would work, what about AEM, Autometer, and other brands

 

I don't think any of the AutoMeter's have a narrowband output, but the LC-1 does.

 

its funny i just had this conversation with a friend of mine, too. Weird. He needs a wideband for his jag and his mechamic said that none have the narrow output. I told him to slap the guy. poor bastard has a v12 and needs two WBs.

 

I would put your wideband O2 sensor as far down the header as possible. The heat can really shorten the life of the sensor. I would also make a copper heatsink to put around the sensor to cut down the temps.
