With the efi software there is a walkthrough to copy your tunes when you insert the disk there is a pop up with an adobe pdf option.
IIRC this is how i did it -
install efi live software onto a laptop. Connect v2 to laptop and then to vehicle. turn key to on position, leave vehicle NOT RUNNING. Start EFI Tune Tool. There should be a black memory looking chip with a green arrow and it should say something like "copy tune" Just click that and follow the onscreen instructions.
I followed the pdf, so not sure how accurate my description is as i just followed the printoff i did so i wouldnt mess it up.
