Default Bogging issue, datalog screen shots included

I hope someone can give me some insight into what is going on with my car. Most of my FI setup is in my sig. Data logging done through KPro.

I have been having some bogging issues when I try to accelerate. I would hit the gas and the car would go nowhere. When the issue is occurring and the engine is at idle the A/F ratio would read 10.0 and wander. This only happens only when the engine is warm.

With the included screenshots the bogging problems started around 4:35, the only thing weird that I noticed is that the S.TRIM goes up to 37% and the Knock Threshold looks a bit crazy.

I am no expert at diagnosing but do you think it could be the knock sensor?

There are no CEL's thrown.

I can also post more screenshots and or send whole data logs to whoever would like to view them.

Thank you in advance

You don't have the wideband AFR logged?
I can take a look at the log and see if I notice anything else, I'll send my email in pm

Flanders was nice enough to take a look at my logs. He noticed that I had an issue with my 4 Bar MAP sensor (I didn't notice it because I have the MAP readings set to a different value......I need to play around with this more). He also helped me figure out a couple of other things with Kmanager too! Ordered a new Hondata MAP from Ballade. Installed it today and just came back from 50 mile drive without and hiccups. Thanks again Flanders!
