Karl,
Are you getting your fuel pressure readout on an electronic flight display? Garmin G3X?

On the G3X there is a set up option for the fuel pressure sender that allows you to electronically compensate for MAP. It works pretty well but it’s not perfect for all altitudes and pressures. I had to play with the pressure offset so that it stays between the alarm points at all altitudes. I don’t know, but I suspect the Dynon has a similar option. I’m sure others here can tell you.

Thank you very much, Jeff!
I think, the problem is solved, see picture. Next tim in the hangar i will check the correct setting of pressure sender.

The problem is solved: Changing the fuel pressure sender to „differential“ mode.
Thank you Jeff for the excellent support!
