I see a Toyota 86 that has been molested by an Audi (thinking R8 ish) and a Hyundai. -
Hey Prank, Any chance you could easily lock all the old FS and WTB posts? Even if it's just a one off hit through there. The majority of posts are people asking someone if they still have something for sale from 8+ years ago, when the person who originally advertised it hasn't been on the site in donkeys years. Just a thought I had. Maybe go through and lock everything older than 12 months or something?

I'd be thinking it's the other way around. Less of an impact when rich compared to lean, but definitely in a lean condition the cat specifically uses up a lot more free oxygen. When rich it's grabbing oxygen from other places to like NOx, but it still gets converted to CO2 and H2O.

Sorry yeah - My post was a mess and I attempted to fix it. In my example both sensors are post-cat. I realized later that I had literally pulled the motor apart and we saw no evidence of any knock and everything was sweet, so my WB was likely accurate (enough!, if anything the engine looked a little rich) In your example I'd want to recalibrate both sensors. I realize this is not possible in the real world. Best you can do is: 1) Calibrate current sensor 2) Calibrate a brand new sensor in same location (do you have an older one to compare to? Or is this a new purchase) Observe any changes in readings. I always thought it was 1M, I am clearly out of date. Mine is likely 2m+. I didn't want to have to choose one bank over another in my application. -
Checking a video I took of another run can see quite a different AFR Graph.
