Greets. Thanx to "Nugent", an attachment he included had some wonderful info on "advanced" re-programming of the ECU, rather than the "Default" re-program.
On the W463, and the W140, the "Standard" re-programming worked fine, but on the W210, I have never been happy with the shift quality going from 1st into 2nd. Following this tutorial, you can "Customize" each gear shift to your liking. I'm not sure how applicable this is for the W463, but it's the same tranny, so if someone wants a different feel, then give it a go!
1- With and already "warmed-up" vehicle (ie. tranny fluid 80C), find a quiet strech of road and "Reset" the ECU by closing doors, turn key to position "2", hold the accelerator all the way to the floor and HOLD for AT LEAST 5 seconds. Turn key OFF, but DON'T take it out of the ignition. Also DON'T open doors. Wait AT LEAST 2 Minutes
2- Start the vehicle, and place gear selector in "1". While GENTLY accelerating, you move the selector to "2" when you feel the shift point is to your liking (gentle, or a little more "racy"), but it looks like for the 112, and 113 engines, keep it UNDER 2,400 RPM.
3- After 2nd gear engages, slow down, and put back into "1", and repeat the whole process all over again AT LEAST 10 TIMES!
4- Then, move selector to "2", and manually upshift to "3" when it suits your taste. Slow down, downshift to "2", and repeat times 10
Well you get the idea. Continue the whole process, all the way up to 4th to 5th jump, but from 3 to 5, you ONLY have to repeat 4-5 TIMES, each.
After the "Up shift" portion, practice the "Down Shift" portion with:
1- 5th to 4th downshifts, 4 or 5 TIMES, 4th to 3rd, 3 to 2, and 2nd to 1st also 4 or 5 TIMES.
Sorry folks, but I left out one IMPORTANT step:
When you are done re-programming, YOU HAVE TO KEEP THE ENGINE RUNNING FOR AT LEAST 10 MINUTES, otherwise, the programming will not be memorized.
The whole process yields a MUCH more "Custom Tailored" shifting scheme. Apparently, this is because each shift module has SEPARATE training logic.
Hope this helps someone else.
