Thank you, Ulf, for the log image.
At first glance, it looks completely different from mine.
I am particularly interested in the area of LD (likely referring to a specific technical term), and the duty cycle associated with it.
Unfortunately, I can't determine what the TV's maximum brightness should be.
I have a relatively constant value of 65% here.
In my image, I used both very aggressive overbites and, in some cases, severe underbites.
Here's a dyno graph of my ex-BUK engine (330Nm / 160PS in a Seat Ibiza 6L), also in 4th gear. It shouldn't differ significantly from an ARL engine.
Note: The TV curve in my logs is inverted, meaning that to compare it with your log data, you need to calculate "100 - my log value". Around 65% in the mid-RPM range should be acceptable.
Now I'm in a fix because after I experimentally shortened and lengthened the thread length on the LD sensor, the LD image is getting worse and worse.
Overshoot/undershoot and significant smoke development during the adjustment process.
I think the loader is going to be removed now.
