Sorry to say it's a Ford issue, NOT Autel. Ford never provided missfire counts in the data line and after 20 years of OBDII doubt they ever will.
Autel did how ever provide access to Mode 6 in the sub menu's so you don't have to back out and go into the OBDII part of the tool. Tech's have been complaining about ford for 20 years, SOS.
I do have a PC based tool that has live miss fire counts for Ford but is a mode 6 edited to show TID 53's, miss fires and it just keeps refreshing the data so you can see the miss fires.
