Thanks for the info. In Illinois, we have to get our cars tested for air pollution compliance every two years. They test the cars on a dynometer. I was concerned about how the ESP would handle it.
DynoMode
Here is an article I came across in Car and Driver on placing the SLK in Dynomode. The article comes with some words of caution. [

Turn It Off—All the Way Off!
For years we've complained about the butt-in behavior of the electronic stability programs in Mercedes-Benzes, which automatically intervene to shut down power and braking when they think your driving needs help. A dashboard switch suggests the program can be turned off, but it can't—it just kicks in at what it sees as a more intemperate level of driving on your part. We were convinced it simply could not be shut off.
Well, Benz lovers, we found a way.
Here's how. To start, turn the ignition key to the first accessory position, making sure the dash display shows the odometer. The SRS airbag light should be on. Press the trip odometer reset button three times rapidly before it goes off. If you do this right, a screen will appear showing a voltmeter. Then press the "up" arrow on the left side of the wheel twice to take you to the "ESP dynamometer test" screen. Using the plus (+) button on the right side of the wheel, select "on." And then start the car. Warnings will appear informing you that the ESP, ABS, and BAS (brake assist) aids are now turned off and you're on your own.
If you did it right, you've put the car in a mode intended for diagnostic testing on a rolling dynamometer—all electronic supervision is unplugged. Unhindered by techno-aids, the SLK's grip on the skidpad improved by 0.03 g compared with simply hitting the ESP switch on the dash. To return all the safety technology, scroll back to the dyno test screen and select "w/t. 15 off" with the minus (-) button. Shutting off all the electronic aids isn't easy, and that should tell you something. Owners are not generally privy to the dynamometer mode; therefore, we will continue to publish test numbers attained with the dashboard ESP switch turned off. We just thought you'd want to know.

Hidden Menus
Did anyone else notice the other menus when doing this? I have a '55, and if I press the "up" arrow only once, the upper display says "Instr. No. R171 540 05 47" What's that about? Also, if you start the car from that screen, apparently the display is showing you the engine oil level in tenth's of a quart. The display also shows "AMGM 113E55"...wonder what that is. Also, at the same time my lower display shows "SW 2604 Ver 0047 HW 0105". I assume SW is the number of the software, and Ver is the software version number. Anyone know what HW is? Also, if you press the "up" arrow 3 times, I get a screen called "Service Menu" which includes "Service Data", "Item", "Addit. Work", and "Confirmation". Anyone know what that's about? I'm bringing my car in for the 1000 mile diagnostic check today...wonder if they will be able to tell that I've been snooping around

Keep looking - you might find the VMAX limit remover []
]Steve-P, how did you know that's what I was looking for? []
]Slktyperice, not that I'm aware of. I will tell you this...after playing around yesterday I did get the distinct impression that the 0-60 time with the ESP fully turned off should be significantly better than with it turned on. In full throttle acceleration starts in first gear in transmission setting "S" the ESP cuts back the throttle much too early and too severely. With the ESP defeated, there is some wheelspin, but you quickly learn to modulate it correctly, and the holeshot is absolutely awesome...and sounds good, too
Can't play around like this too often though...can't be good for the powertrain, and those rear tires are much too expensive, but WOW 1 - 10 of 10 Posts
