To use one of these to see everything, ie, mixtures other than just the perfect 14.7:1- would I need to weld in a different sized bung to screw this into.....................

You can use the one that your narrow band is in, since most can be used as a wide band as well as a narrow band.

yep, same bung as your narrowbands. Most kits come with bung.

Before. You need to see the exhaust before the cats muck with it.

Just got it going this weekend - wanted a separate bung for it. It's wired into the ecm through egr, and I've got HPT recognizing it.

But I think I may have a ground offset problem - I think I'm seeing about .2 richer in HPT than what the display is showing me when under wot. Really haven't had a chance to lay down some good runs to test yet though. Plus I haven't decided where I want the display itself to stay so I've sorta been trying to hold it and watch when I punch it...

I'll get it sorted out. Worst comes to worst I can always upgrade to a pro unit - but that's last resort!

I have heard that if you put it after the cats, it's only off by like .1 or .2 I know that's a difference but not too bad. I'm sure someone will correct me if i was wrong in hearing that.

I thought it was .5 off if you were post cat. I plan on replacing one or both of the stock o2 sensors and going with a FAST dual wideband setup, send the 0-1V back to the stock computer.
