I'm having a very hard time replacing a pcm on a 2007 f350. there seems to be no programing capability built in for ford? usually you would hit the icon for replace pcm/program the unit should then copy the files from the condemned pcm for install/overwrite to the new pcm but I find no such option on this screen. I purchased this unit solely for this reason, I was told It was capable of pass through programing and on autels web site they say it is but this unit will not give me the option. what the hell?
