Hi,
Im new to the Forum and to tuning in general.
I want to learn it, and i already picked up on some things.
If someone has posts in this forum or other helpfull Info on how to make xdf files,
i would appreciate them.

Also i have question.
Ive heard about OS's and that you can use an xdf File with the same OS.
 Is the OS described by the Bosch software version or the ecu name?
And how much do i need to change if i have an xdf wich describes the same OS?

Thanks i advance for any answers
