Shawn, I ordered a cable it's on its way.
I am downloading E-Sys 3.18.4 right now.
Now I just need the PSDZdata for the 2013 M5. Which looks like is the 47.x version, which the link is only to the 46.3 version.
Do you have the newer files? I can provide access to my FTP where you can upload them? Thanks for the help!
