It could be a leak. The fact that it's rich on one pull and way lean on the next means something isn't right. It was hard to tell from the photos, but is the primary o2 sensor horizontal in the pipe? It's not going south to north by chance?
Ok, I got everything rotated and it's still all over the place. Could I have the wrong sensor??? I am finding 2 different part #'s, the one you recommend 13940 and the one I think I ordered.

The fact that Parts Geek is the only site I see that shows that part number makes me a little nervous. When you go to Bosch's site, it shows the 13940 is the number to get for the upstream
https://www.boschautoparts.com/g/oxygen-sensors.
Parts Geek does show the 13940 though,

they definitely sent me the wrong sensor. I'll have a datalog shortly. Far right is the Bosch.

I think that was it. Things look a lot more consistent. The Denso works.

Yea it definitely looks a lot better. I made some fueling adjustments based on that datalog.

I'll do a datalog, then I will be ready to put in the RDX injectors

Okay sounds good. I’ll put together the RDX file then. You'll need that to start it.

Looks good. Still needs some work, but since we're moving to RDXs we'll just start there.
Here is the first one for the RDXs. Take this one for a 20-30 minute drive and only do one WOT pull in third gear so we can get some data before you have too much fun with it. In theory, adding RDX injector on a tuned car should yield very close fuel results, we still want to be careful until we get some data.

That's feeling better. The kick at part throttle when it hit VTEC is much more noticeable.
