I'm very early in my tuning knowledge but I know using a Wideband to see what is really happening is highly recommended. I've searched and see several references inside of other threads somewhat related to the issue but what I'm looking for is people's opinions based on their experiences with their choice.
My intention is to use the wideband for tuning and scanning only. I'm not planning to hook up an active display that is always running.
I guess my choices are:
1.) remove one of the NB sensors and put the WB in its place for my scanning/tuning runs
2.) have a new bung welded in and I guess install the WB when I want to scan/tune and remove it and plug the bung otherwise.
Is there a 3rd choice? Like do #2 but leave the WB in?? I wouldn't think so, but this is why I'm asking.
Are there advantages to installing a separate WB bung as opposed to removing one of the NB for scanning and tuning purposes.
Also, if I remove a NB, does it disconnect so I can physically remove it from the car and leave it in the garage until I'm ready to reinstall? Or do I have to protect it and tie it up somewhere out of the way under the car while the WB is installed.
I have LG LT headers with hi flo cats and when I get under the car there doesn't look like there is a lot of room for another O2 sensor.
Plus, if the stock NB is removed and replaced with the WB, then don't I need to turn certain things off in the PCM?
FWIW - I have a 2001 A4
