I have a "new to me SR22" that has Entegra PFD/MFD along with IFD 550/440/DFC90 installed. Everything works great other than the Synthetic Vision attitude display on the 550 is always showing a pitch down display and never changes. It is this way on the ground or in the air. The heading is properly displayed, but attitude is wrong. I did not see any information on calibrating the unit or any troubleshooting in the manual. Sorry for the sideways picture - new to this site. Any info is appreciated.

| Section 7.5.22 of the Installation Manual has the calibration instructions that might help with your situation. |

| Thank you for the manual. The calibration process fixed the issue. My installation required a -28 degree offset. The TAS was also not set which I assume helps aid in accuracy in cruise flight. |

| Same issue here. Just installed an IFD550, but the shop didn't configure this. |
