I don't know why everyone isn't seeing what obviouslly really happened...
The ECU had a number of pre-defined fuel maps... Then the Top Gear production office calls and says "We need a car in JeremyClarkson size. So someone in management calls down and says "Ja, Werner, please machen ein ECU ready fur TopGear bitte, mach schnell!" but it's friday night and Werner has a date with a couple of Medchen in Dirndle so he switches the fuel map, cranks out a .hex file, and then goes out for sexy-time with the ladies...
Monday Morning, Werner comes back to work with a big grin on his face and sits down in front of svn which tells him he has some local changes... His face still a little sore, he's not thinking and just does "svn commit"...
Bam....
I'm in the wrong business... forensic engineering is my calling.
