you know there are websites and forums that teach you how to code these yourself for free..its not hard nor does it require equipment. They even supply the software necessary.
matter fact its common knowledge way before the E9x came around.
just use google and search for bmw and coding as the admins have seem to blocked out the website on this forum.
And some might argue that there is danger to ruin your ECU or whatever, thats a lie. You can always revert to original file if you do it correctly, but who wouldn't do it correctly?
