It's going to be a great help for you, and those on this forum you ask for help, to get that engine code off the firewall and add it to your profile settings (instead of the present "I.D.K.?") I'll guess a G63B but I'm really not that keen on the designations, yet. It makes a huge difference for those who know, though...just as I know how to respond with others who have a 4G64 (Are you SIRIUS!?).
