EDC-D10A - Heading off by 40degrees!

[Steve.N]

Guys,
I've installed a D100 & D180; no matter how accurately I calibrate both compasses they are constantly off by 40 degrees.
I'm running firmware 5.6 & have followed the instructions to the letter

Please help
Steve.

What aircraf type ?

Where is the EDC located in the airframe ?

Did you use a handheld compass to find the most magnetically benign location ?

Also, where are you in the world, and what are the numbers that you plugged in for the magnetic intensity and inclination values?
