SMG II CSL and European Spec for 2000-2006 M3 SMG

Our SMG software has been tested in numerous vehicles with countless hours of logging. Our final product maximizes your transmission without sacrificing the life of your transmission.

How it works:

1. Install the supplied software on your laptop (Windows XP/Vista/7)
2. Connect the cable to your OBD-II port and read your ECU into a file.
3. Email us the file
4. We tune the file, email it back and you use the BPMSport cable to load the new tune back into your vehicle. You can replace your original/tune file at will, and of course if you add modifications in the future, you use the same process to load on the new file we send you.
