DA62 Load vs Power

Hi all. I have a few hundred hours on the DA62 and more on the da42 both NG and “classic”.
Would like to contribute some improvements to the MSFS model if possible, specifically mostly relating to engine handling / indications. One glaring error: turning off an engine with the master switch does not make it feather (above minimum feathering RPM).
Can’t seem to create a new topic.
Please PM me if you would like more info.
Cheers
