This brings me to the question, how can I hook up an AHARS so that the synthetic vision I FLY provides would be accurate.

I have the Dynon D19 that gives accurate attitude info and many other items and I use an Android tablet from Samsung.

So is there a way to use a dongle that will feed IFLY to give accurate attitude on the EFIS screen?

The iFly AHRS information is as accurate as the information being sent from your ADS-B device. Mine is a Stratux with WAAS GPS. I don't think there is anything more accurate. I don't know about the AHRS unit that is internal to the Stratux, but it seems very percise with no delay to me. If there is any lag, it would be more a function of your iFly device processor and/or memory, etc. I use an iPad Mini 4 and I see no delay.

EDIT: The Stratux internal AHRS device also has a pressure sensor allowing iFly to give you pressure altitude in addition to altitude derived from GPS. Per FAR's, we all fly according to pressure altitude, not GPS altitude.

Correction on my post. My DYNON is D10 not D19. 

There is supposed to be a dongle that gives accurate AHARS without having to buy a Stratus. I don't know how it would feed info to IFLY on my Android tablet. For instance, tIFLY pick up my ADSB via WiFi, but could it work with two WiFi signals or a WiFi for ADSB and Bluetooth from an  AHRS dongle.

My ADSB is accurate, but the synth vision on iFLY is too slow to react to attitude change. The horizon overreacts to any pitch movements.

I have read the post where pilots are seeing if they could land with the synth. I am not even going to try this since my synth will be my out if I have an engine failure above an overcast. In this situation, the synth will be useful in getting me below the cloud layer, hopefully before impacting terrain.

I have simulated this benefit and it works well.

No, you need an ADS-B device feeding information to iFly on your tablet. Don't you want to see traffic and weather also? There are many ADS-B in devices that will work with iFly. I use Stratux, not Stratus. You can build one yourself or buy one right here from AP.

I guess I should add that it's possible there is some sort of device that I am not aware of to feed AHRS info to your tablet running iFly GPS. If there is, I suppose someone from AP will post it here.
