Hey everyone,

I recently flashed the DME on my 2002 M5 as per nightkrawler's thread and WOW, WHAT A DIFFERENCE! I had learned to drive the car as it was and was able to compensate for the jerky throttle but... Everybody needs to do this update!

That aside, I noticed that there are two (newer? bigger numbers at least) versions of the DME software in the latest daten files v53.3.



As you can see, there are two newer versions, 7843311 and 7843313. Has anybody tried these ones or know what they are? I'm tempted to try one of them and see if I noticed any change as well, but the "euro" flash that everybody uses (7837963) works so damn well!

interesting... idk why they added those sw versions but they are usa versions, not euro so i doubt the throttle mapping would be good. as a rule of thumb they usually don't make things better in terms of performance when they come out with updates, stricter emissions etc. anyway you can look at the files yourself, there is some info in the header of the program file.

ie in winkfpt the program # 7843311, so open up(use notepad for all these files) "MDS52.DAT" and find that #, then look under the "SW-NR" header for that # and you find 7843312DA, now open the file 7843312.ODA and you see,

so we know from this that its a usa version, its for cars with cats, for the m5 not the z8, and it was written in 2009. why they are adding these 5 years later idk.
