For those of you who have welded in a bung for a wideband O2 sensor, how long was the bung? Does the sensor extend out of the end of the bung when it is screwed in all the way?
I have an Innovate LC-1 wideband (which I'm very happy with, btw). For a couple of months, I ran it in the rear O2 sensor spot with no problems. But, just on account of it being more accurate, I decided to have a bung welded into the pipe further upstream. I had the midpipe out anyways during my recent motor swap.
I used the bung included in the Innovate kit. However, I noticed that the wideband sensor doesn't extend out past the end of the bung once it is screwed in all the way. It is flush with the end of it, at best. I thought this might be by design so that the readings won't jump all over everywhere from the exhaust turbulence.
Well.....the readings jump all over everywhere anyway....at idle, it will go from 10 all the way up to 18ish. At part throttle cruising, it will vary similar amounts. At WOT, it shows it being VERY rich (7-8 kind of rich), and there's no way the car is running like it is being that rich. Getting on and off the throttle will cause it to vary from full lean to full rich.
So, is the fact that the sensor isn't extending out past the bung causing this? Or do I have problems elsewhere?
