PIDs have to be set up just right and the Infinity is very very touchy with it's VE map set up in the way that if it isn't expectionally smoothed out, it will do weird stuff like this. What does your fuel pressure look like and do you have a fuel pulse damper?

Double check your wall wetting table and set up while you're looking through as if you don't have any spare columns next to the zero throttle per second column, it would trigger transient events an unstable AFRs like you're seeing and you'll be chasing your tail for quite a while. My Integra had random variations from zero to ten throttle per second changes because feet aren't precise in holding throttles in one place and caused a similar event.

Looking at my Throttle rate (different than throttle percentage) there is very similar patterns to the oscillation and I think this is the culprit. I should have noticed this earlier if I read your post clearer. I'll post back with details after I get time to drive it again. I really am questioning the experience of the previous tuner who did all the work prior to the rebuild.

There is a sub menu for idle which you can set inputs where the idle range would be. Ex. Idle below xx% of throttle rate along with xxxx RPM. I think this is what you are talking about when translating languages from ecu's. I could be wrong. I also have filter settings for the tps sensor but that's more for electric noise for smoothness.
