Resetting Throttle?

*First Post*

Hey guys, I read somewhere that you can reset the throttle of your E Class giving you some better response? How do you do this?


I have a 2003 E320 RWD Sedan

Thanks!

Not quite sure what your source was referring to, but it may have been one of two things:

1. Keep the "W/S" button near the gearshift lever in "S". That allows the car to start in first gear instead of second; faster off the line at the expense of fuel economy. "W" is for snow or ice on the road.

2. The car supposedly adapts to your driving style, so for instance if you drive aggressively, the ECU (or whatever) will "learn" to shift at higher RPMs than if you feather-footed it.

If you mean reset the Engine Control Unit (ECU):

The reseting is a pain in the butt. It only lasts about 3-4 days of normal driving, and then you have to do it again.

Get yourself a sprintbooster.

Is 3 or 4 days really enough time for the ECU to "adapt" to your driving habits ?
