Can I hook up my wideband But Drop the O2 sensor?

that is the question.
I would like to Put My Wideband gauge in the car But I only have the ONE Bung on the Header(yes,it is an N/A for now..TII Keg in the Wings, awaiting.).So can I just put the Wideband Sensor in where the stock O2 Sensor is?/.What will Happen?..Car run like Crap?
I'd usually just go ahead and DO it.But I'm just about ready for a Spinal operation here,and can't Move around without Intense Pain.Save me some Pain..Answers would be appreciated.Thanks.STYX.

You can use the wideband O2 sensor in place of the stock sensor, as long as you hook up the 1V output to the stock wire. The only thing is that you should really mount the wideband sensor far from the exhaust ports to prolong its life. I think 36" from the ports is recommended. This is why the kits all come with an extra bung to weld on.

Thanks RR88..I think my Bung is at the collector.(if my memory serves me right.).It's a little bit of a Fabbed piece.

Most wideband gauge kits do not have a simulated 1V output. Which brand and model are we talking about here?

A heat shield is a good idea for rotary engines.

See diagram 3.2 here:

Also, bung extender here:

I have an LC-1 and just did this. The narrowband simulation works well. I had to slow down the response time to get it to work though.

You will probably need the bung extender. I was overheating the sensor almost immidiately, although my o2 bung is in the stock location on my header.

I have had no overheating issues since installing the bung extender.

no u dont have to run oem o2 sensor it only works at idle speeds like when i plain out so to speak not accelerating but keeping a pace and when it comes on it only makes like .3 afr difference so it has no purpose really supposed to save fuel but on a boosted 7 it
dont do much and yes between 18 and 36 inches is ok

Yeah, not all widebands have the 1V output (AEM, NGK...), but the better ones do. Innovate & PLX for instance. The OP didn't say what brand / model he has, so I'm just generalizing.

^^ It's a rotary... Does it matter?

Also Your correct rocket, 36". Also anywhere between 10 and 2 o'clock. Most people run there widebands where the stock o2 is. That is a no-no, there's too much heat that it'll burn the sensor.

besides burning the sensor, you'd waste money on buying one in the first place. rotarys are making mad fire down the down pipe. so try not to beat on it until you get a new bunge for the wideband.
