 If you have ADSB In and out and are using an iFly 740 for monitoring  updates on Wx and Traffic, Do the TFR updates get  transmitted thru "that" signal or do you still depend on the IFly update  "checked box"  for Weather ,TFR and  Fuel Prices to update that for you.  ??  and If you update during a current  local TFR will that remain there on the screen until  you update  via  the iFly  checked box  Wx, TFR and fuel Prices. ?  I know thats not the case for weather.
 
Yes, the TFR updates get transmitted thorugh the ADS-B network on the 978 band. TFR's should show on the map even if you don't have METAR/TAF checked. The TFR will disappear on it's own after it has expried.
