Looks like signal noise from cam sensor.
You can try 2 missing tooth decoder.
Hoever I think the only solution is to disable cam sensor over 600-700 RPM

tried HALL sensors connected here, and VR
but interference with VR was smaller

trigger type I tried them all, but either did not start or still the same problem

Tomorrow I'll try to disable cam senzor
thanks

Actually to fully diagnose the problem you need to use scope and check the signal shape, noise and so one.

do not oscyloskop available
I have to ask a friend to help me

The fastest solution for me is to try to disable the cam sensor,for now

I used the standard VR Sensor with Hall and pullup settings. Works perfect. Do you use a sheilded cable all the way?
If you are not planing on running Vanos you can just disable it över 600rpm.
