Replace Narrowband With Wideband?

You guys talked me into buying a wideband for better tuning and after doing some looking around, I found this:

I like the idea of being able to replace my stock narrowband with a wideband sensor. It would save me the trouble of pulling the rear header back out to put another bung in. Has anybody here used this setup? Anybody have any input about pros or cons of it?

I didn't buy the HPTuners Pro so this would theoretically allow me to do a wideband tune and be able to track it in my tuner side by side with other data. I was hoping it might help out the pcm also if it has more accurate feedback than the oscillation of the narrowband O2. Thanks for any info you might have.
 


its easy enough to put a bung in before your cat if you have one. if you dont have one then you have a ton of room to put one in. it doesnt need to be super close to the downpipe if you dont want it to be.

however, many people have replaced the front o2 sensor with that setup and had success.
 
I have a write up in the how to section on how to log afr with a wide band with out the pro interface assuming you deleted your egr system.

I thought about doing it, but I don't want to give the emissions police an easy one like that to get me on. MA looks up to CA as a role model for how they should police vehicles so I try not to make it that easy for them to fail me on inspection. Once it hits 15 years old, then emissions don't apply anymore. Just safety inspections after that.

I know widebands give a more smooth reading than narrowband sensors, so would this have any effect for good or bad as to how the car would run? I don't want to have the PCM get upset with me not having the big oscillation that it is used to seeing from the narrowband. I was hoping it might even run better since it would have a more stable and more accurate reading.:confused:
