D100, roll servo calibration?

[Sportpilot]

I have a question regarding the D100 with autopilot. When flying a gps approach the CDI needle is a bit of center, both the EFIS and the GPS (AVMAP EKP IV) shows the same thing. The autopilot does not appear to make the last little input needed to center the cdi needle. The scale setting Enrute, Terminal & Approach doesnt seeme to make any differens. When flying enroute the CDI-needle is always centerd.
Is this anything that can be corrected in the roll-servo settings in the EFIS?

I had the same issue. My setup is different since I have the HDX driving the servos. The needle was slightly off center and the plane was lined up perfectly 100 feet left of the center line with no attempt to align with the runway. What fixed it for me was to increase the “CDI dot gain” in the HDX. It was an added feature in the v16 release. I’m not sure if this is available in the D100.
