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.
Have you find any performance improvements going from 220E to 231E? Thanks in advance.
