Quadplane Auto IC engine Control Support

I am using Mission Planner to fly my Quadplane. I would like to know if anyone can help with any link that shows/explains the connection system and parameter settings for Auto IC Engine support.

I searched a lot through the site but couldn’t find any forum or links related to the Auto IC engine control system even though they have mentioned this option is readily available from 3.7 onward.

Looking forward for kind help.
