For now I'll leave you with a teaser pic which shows the UIF field in the factory file. This file was the same file the factory programming system programmed to my car yesterday. Instead of looking at the one that I read out from my car after the program, I imported the factory data file straight in to take a look. You can see 240E identified in the red box:
