Running lean O2 recommendations?
 

So I’m in the middle of the biggest “while you are in there” cluster eff in existence. I started replacing a broken torsion bar and then I ordered an entirely new rear suspension then front suspension then valve cover seals and sensors and valve adjustment and.....

Anyway I yanked my spark plugs to do the cap and rotor and spark plugs and a leak down test and there was a faint white crust on a few of them which I’ve heard suggests a lean condition. I have a Steve Wong chip configured for a cat bypass but I had to stick the cat back on because I moved. If anything I would think the cat bypass config would create a rich condition - not lean.

Anyway. I figured. Let’s just stick a wideband sensor in it while I’m already dropping insane amounts of cash. And since the last thread I see is from 2017 I figured I’d ask to see what people recommend. Ideally something where I’m not having to weld another bung in and I can use one sensor for both my DME and wide band gauge. And something that allows me to download my data to some kind of spreadsheet so I can see what’s up.

Anyway. Rant over.
