MS2 1,6 NA idle drop

Hi,

I would like to get some help with the idle drop.
The idle is quite good and stable at 900rpm and is in closed loop. When I decelerate and press the clutch, the idle drops and recovers.
I use the idle advance timing and this helped a bit, but it stil drops to 660rpm for a moment and then the rpm recovers to 900rpm.
Any advice would be helpful.

Thanks

raise cl idle control valve dashpot so it drops to 100rpm over target then settles in.

I've raised the dashpot from 2 to 4,5 seconds.

I's a bit better, but still dropping too low

Also changed over run fuel cut from 1200rpm to 1650 rpm

again a bit beter but not good enough.

drops to about 700 rpm...
