The dynon cannot feed ADSB traffic and weather to the IFD. It cannot feed fuel flow, at least not directly from the skyview system.
I have a HDX system and an IFD 440. Having a map on a large 10" screen spoils you. It makes the IFD 440 map screen small, which it is. Adding weather and traffic to that small screen would border on useless. My IFD stays in FMS mode 95% of the time and I look at the IFD flight plan on the Dynon screen, along with weather and traffic.
