Please translate next time. This is a mostly english based site, so if you want help it would be good to post in our language.
The recommended value is 2-9 mg/s idle for vag com.
But, 4-6 is usually best in my own experience.

Ok excuse me, then she says a value 4-6 If I instead would set 4.2 / 4.6 / 5.2 / 5.6 ElsaWin or how he speaks what are the changes?
While a value below 4 type 3,8 / 3,6 / 3,2 ----- 2 2 in which I would go to encounter problems?

I know that it is an old topic but I would like to fine out more details.

Let's see if we increase the size for the voltage pump we will increase the granularity for controlling the IQ and also can have a higher reference into IQ axes.

Now, how can we readjust the voltage pump in order to define as proper as we can the IQ?
