I knew at some point that Bung reference was going to come and Bite me in the Butt (no pun intended)lol
YesSo the wide band is located after your X but before the cats, correct?
Just curious as I'm thinking of getting one, why did you think it is one of the best?One of the best AFR gauge kits available
Thank you for all that info too,specially the bungs,i wasn't aware they were 2 types,seems like stepped is the way to go, hole is already drilled and you dont risk ruining the thread on the new bung while drilling the hole plus our welder is a bit temperamental, anything i can do to make his job easier he will like that,lolSoon at work, I/we will be installing a pair of O2 sensor bungs for the wideband O2 AFR gauge. These come with plugs. We are installing two and are purchasing these with the plugs in case we thought that we had an engine problem and wanted to momentarily swap to the other side. They will be 1.5" from the stock narrowband sensors and clocked at about 11 next to the narrows that are at 9.5.

ADDED: Here is a link to just a pair but they don't have the step which I prefer. If you use the non-step ones, make sure the hole in the pipe is big enough for the sensor.

Has anyone here ever used the AutoMeter wideband gauge?

Here are a couple.You really need to post a link to what you're referring to.
There are stand-alone gauges that require a signal from an actual wide-band to reflect useable data and then there are wide-bands ("kits" so to speak) that include a gauge.
Now... You can take a simple AFR gauge and feed it garbage from a narrow-band sensor but the readings from the display are utter gibberish; nothing more than a light show.
I have used an analog autometer gauge to display data sent from the analog feed of my Innovate LM1 wide band.
I do [not] like digital gauges in my 80's era Fox Mustang.![]()

I'm splitting the signal from the wideband sensor when the Moates QuarterHorse device is attached to the pcm and the RT results are appearing on the "laptop" digital dashboard.
I hope this discussion helps other people.

@OX1 The two that you are comparing, do they both use the Bosch lsu. 4.9 WB sensor?
Normally I agree, but A/F just seems harder to read analog to me, especially idle/part throttle when it is bouncing around a lot.I have used an analog autometer gauge to display data sent from the analog feed of my Innovate LM1 wide band.
