Guys, sorry, newbie here. I've searched last night and tonight and can't find out how to "write calibration" with VCM 3.0 I have. I just re-downloaded and installed. I have a 13 Mustang GT 6spd manual with the Copperhead ECU. I can "write entire" but worried about doing that with all the warnings I see about that. The only options I get in the write dialog window are "write entire" or "do not write".
I know it's probably right in front of my face, can anyone help?
