I have an SCT X3 tuner that I have married to my 2003 V6 Mustang that I just found out has a cracked screen. I can’t view any of the info on the screen so I can unmarry it so I can use my SCT X4 instead. Does anybody know the button sequence that I need to do to unmarry it? I searched Google with no luck. I haven’t tried to contact SCT support yet, but they may not help since the SCT X3 is no longer supported.
