PD: Relationship Between Rotational Speed & Sync Angle

Hi!
Ulf has brought up the topic of reluctance in permanent magnet (PM) motors and also explained a very interesting (optical/mechanical) control method. In another thread here on the forum, we had already discussed the synchronization angle in PM motors. /viewtopic.php?t=4893&highlight=
Theoretically, it would also be conceivable that an electronic verification is possible.
It might be interesting if all PD engine owners could briefly describe their experiences with engine revving using VCDS, and also provide the synchronization angle. As additional information, it would also be interesting to know whether it's the original timing belt or if it has already been replaced.

Thank you very much.
Dirk.

P.S.: I intentionally created a separate topic because I felt that Ulf's topic hadn't been fully discussed yet...

OK, I'll start.

Unfortunately, I only have one log with the correct NW setting (I didn't create any before).
In the range of 2000-4000 rpm, the values are now predominantly between -1.1 and 0 degrees.
The 0° reading is in the upper RPM range, while the -1.1° reading is closer to 2000 RPM.
The engine pulls strongly in 3rd gear, and even beyond 4000 RPM, it shows no signs of struggling.
