I ran the update tonight. It was very easy. Just download the files in the torrent on one of the previous posts and use the info from the OP (I used the PDF and the program number). the programming only took ~30 seconds to complete. The longest part was setting up the program and importing all the data.
After the update, all I have to say is WOW, What A Difference! This is probably the best mod anyone can do to the M5. Shifts were significantly smoother than before (even when I was driving in S5) and the car will undoubtedly be more comfortable on my daily commute. I didn't try D1 because I normally drive the car in S5, but I bet it is much smoother as well if the S5 performance improvement is any indication.
I hadn't tried launch control yet so I took the car out to a nice long and straight country road and tested it out for the first time tonight.
Let's just say, make sure you tuck in before you let go of the shifter
. I followed the launch control instructions and right when it hit 4K RPM's, I let go of the shifter and the car almost immediately red-lined while spinning the tires. Thanks to the new program, it up-shifted automatically at the red-line. It spun the tires through second gear and finally caught the road when it shifted into third. Next time I try this, it will be on a better rd... I couldn't get any traction... When I got home 5 minutes later, I could still smell the burning rubber... I smell a new set of tires in my near future :M5launch: hiha
