What are you guys using for affordable
Wideband UEGO Air/Fuel Sensor
just for tuning purposes

If you have limited funds, they might be better spent at the drag strip or on a dyno since those actually measure performance.
I see. Definately good to track effect of changes.I bought the one listed above for My 440 / 500 Stroker. I never set up a Holley before and it helped greatly as mentioned to see which direction I was taking things. It has since stopped working . If it was still alive I would have welded a bung and used it for tuning on my 340 Ragtop. Too much money for the short time I got out of it.
I still suspect a vacuum leak on my 340 since rebuild as it runs lean and I have to run half choked until really warmed up. I am soon the add a Air gap intake and then final tune carb. I have an AVS (originally on motor) and a Eddy 625 ABS (currently on motor) Thought carb needed rebuilding from sitting but ran the same so I rebuilt the Eddy and got the same results.
I tried a few tests for vacuum leak but could not find one. My gut still tells me it is. Car ran good before rebuild with the AVS. Kept most everything the same but 20 KB pistons and Eddy heads. Compression is all about 160 +or- 3 psi.No way to pinpoint what failed?
Does the gage read anything in free air?I tried a few tests for vacuum leak but could not find one. My gut still tells me it is. Car ran good before rebuild with the AVS. Kept most everything the same but 20 KB pistons and Eddy heads. Compression is all about 160 +or- 3 psi.
Absolutely 100% agree. And if you’re running a modern efi your o2 sensors better be damn accurate and you had better trust them because the ecu is.Sorry I disagree. Wideband has helped me in numerous ways, and 'around here' a dyno (and a track as well) is rare and expensive. By the time I drove or trailered to Spokane round trip and spent money on a dyno run, all that more than paid for the cost of a wideband. I realize they have limitations and are not "lab quality" so to say
In my opinion the current crop of affordable O2 meters are one of the best things to help guys who are "alone" in the hobby with limited test equipment
Another great tool is my old G-tech or some other onboard performance device. G meter is very helpful
Does the gage read anything in free air?
The sensor can handle it. Whether the gage will show it I don't know.
That's how Innovate has the user check calibration on periodic basis.
Now that I typed that, I realize that at least with the LM1 & 2, the free air check shows percent oxygen - not AFR.

Maybe @TrailBeast can explain how its done with the gages.
