What does your wideband say when you leave it in gear and coast or turn key-on (not start it) after car has been sitting for several hours? Mine says 22.3. Air has a known oxygen content so I'm curious if your sensor is off then too.

I just bought a separate gauge and grounding the wires with the maf-t wire made the reading off by a certain amount and grounding separate the reading was still off but closer to the one shown on the maf-t. So I just changed the output for my wideband aux signal and now they match. I assume the one shown in the maf-t was correct because it shows 22.3 in air. Not sure why I couldn't get them to match originally, probably the wiring though since it changes depending on how it's grounded.
