In the manual the Idle advance is correct.
RPM lower than Target increase Ignition and higher decrease.
But in reality it is like this. Lower than Target he decrease ignition.

The RPM delta is equal to: [Idle Target RPM] - [Current RPM]
900 - 1000 = -100 here he incrase the ignition
but correct it was decreasing because the rpm was 100 to high

this works but it is not correct

Hi, yes that is the way it is. It's not intuitive, but it is logically consistent and correct.

Thank you for the quick response.
if there is no bug the manual has to be changed.
It is confusing.

But it works

Thanks again
Frank

I thougt change the Calculation and done
The RPM delta should be: [Current RPM]-[Idle Target RPM]

But it works

Thanks again

The problem is the picture in the wiki, right? The text is all correct. Do you agree?

"The RPM delta is equal to: [Idle Target RPM] - [Current RPM]

Generally timing will be added (positive values) in order to try and increase RPM and timing will be removed (Negative values) to reduce RPM."

I hav read this but not realy. i only keep the picture in my mind.

yes text is correct to the calculation target - current. the picture do not fit to the calculation.
So it works but it is not correct.

the picture in the wiki is perfect. That is the way how it should be.
Maybe in future you change the calkulation to current -target.

But the good thing is: IT WORKS
