I replaced IACV Wednesday and immediately i did the 60km test ride without idle problems.
Today i did second test ride 125km and still no idle problems.
Cold engine work on 1400 RPM and after 2 minutes 1300 and after nexst 3 minutes it gos to 1000RPM
Until now no issues. .... don't worry i understand Your pain. I will report every day.
I don't want to announce the verdict to early ..but until now IACV replacement solved the issue for my bike.

I have just ordered a new IACV valve in order to replace it as soon as it arrives. As SportsterDoc said maybe it is wise just to replace it given the high probability (and cost: valve, o-ring and deliver about 185€). I sent a message to the German dealer who made the repro to Wisedrum but no answer from them yet and my dealer in Spain seems not to know about that Software update. Still I am wondering why after a pulse train the idle drops.

1- Pulse train trying to open the valve but the valve closes instead - Bad IACV
2- Pulse train trying to close the valve and the valve closes thus lowering the idle - Wrong output from ECU
Just let's see how it behaves when replacing IACV.
