I spotted this W211 thread on another forum last night and wondered if anyone here has heard of it or tried it.
"You can reset the tcu/ecu to factory specs which makes the transmission more responsive with higher shift points"
This is the instruction to do it:
"Get in the car,close the door,turn the key to the on position,---not to run--- ,just to the position that all the lights come on,the reason for this will be obvious in a second!!!!!!!!!!Step all the way down to the floor on the gas pedal(reason why you do not want it running) and keep your foot floored,while keeping it to the floor,wait 15 seconds,still keeping it to the floor,turn the key to OFF.Now wait a few seconds and let your foot off the pedal.Now sit there for 2-3 minutes,and then exit the car.Please follow these instructions to the letter,some people have been known to not read the caveat about the engine not running and sit there with it floored and on the park position rev limiter and wonder why the engine shook and cut out at 4000 rpm.....
Also some cars that have been driven in a stately manner will go from very docile shift points back to the much firmer higher rpm factory settings,so use you foot accordingly.
some cars wake up more then others in response to the reset.
While you are waiting a few minutes to go for a drive,take that time to check your oil,examine your belt,look around and enjoy day."

Might give it a try...
