The reason LTFT changes is because the DI:PI ratio changes. LTFT is doing exactly what it needs to do to compensate for the DI:PI split. It's so high because you messed with the maf scale in areas that CL hits. You would have been better off keeping the Stg1 maf scale and only touching OL above 3.3V, you could even let the tool spit out a maf scale for you,which you can't do for that scale you have now.

You can revert to this one, and use the exact values the mafscaling tool provides above 3.6V, which would produce something like this.

64.7
83.0
107.3
127.0
144.6
175.8
205.7
247.5
305.0

Another delusion people will have you believe is that AFR has to follow commanded AFR, so you need a MAF scale tuned to an inch of its life and lumpy as fuck. You don't.

Also, LTFT at idle is 100% absolutely irrelevant. If you give people logs when the car is idle and LTFT is X, people are going to look and go "LTFT is high", and make you focus on irrelevant stuff that wastes your time.

If you want to see perfect LTFT in OL (where you spend 100% of the time on track), go back to your very first logs which the vanilla Stg1 MAF scale.

Take the tune attached, drive 100km, then log on the street and pull timing out where needed, keeping it absolutely smooth in the process. Ignore knock on the track, there's no point taking timing out based on track data, you'll just de-tune your car that way. Don't just blanket remove timing on the whole map when there's no knock or knock only in one area.

Here's a log on of Stg1 on MT with regular DI/PI ratios

Here's a log of Stg1 on AT where I must have been running with 100% DI, but same MAF scale, same AFR as 20% PI, but different LTFT which makes it happen.

Here's another one, it apparently adjusted and leaned out after this.

Another MT

You want to be hitting around 11.7 on OFT or 11.6 on tactrix at 7000 rpm, +- 0.1.

Running leaner than say 11.8 is great for the street, for one pull. Shit on track.
Your fuel is only E5 so not really enough E% for any great cooling benefit.
