BLS Startup: BMP vs. BMR (mPD vs PPD)

Hello.

BLS and BMP (both mPD) seem to start "from a high point," meaning they have a relatively high initial setting that is then immediately adjusted downwards. This results in a quick and very responsive start. I even think I can detect a slight overshoot on the tachometer.

The BMR (PPD) seems to be approaching the issue from a grassroots perspective.
He realizes that he's not running properly yet and increases his stride length/momentum, until he finally starts running. It looks slow and sluggish.

The test objects are:
3C Variant 11/06, BMP 93,000 km.
3C Variant 02/07, BMR, 61,000 km.
1K, 11/07, BLS, 123,000 km.

Can someone tell me more about the significantly different startup process of the PPD?
Does it confirm, refute, or explain why everything is so different?

Okay, here's the translation:

Thank you.
Martin.

Can the "new diesel" engines, specifically those with PD and PPD technology, have their injection timing adjusted?

When I try to modify the start moment alignment A001, I get an error.
The idle speed can be easily adjusted.
And the BMR (blower motor resistor) still runs smoothly at 750 rpm.

Is there a way to adapt anything (other than WFS) to BLS?

...at least, LBL doesn't offer that.

Bug or feature?
