Forgot to mention...
In the US we run software from bmw which references "National Version Korea".
There is also a Japan Spec, China Spec, and Euro EU5 emissions standard factory files, and of course the Euro Spec M3 GTS software for the 4.4L S65 motor.
I am going to check out the differences between all of these revisions and load the EU5 Euro file into my car and see if there is a noticable improvement over the US software. I have all of those revisions stemming back to 160E, but will focus on 220E, 231E, and 240E.
