Edit: I have not tried spinouts w/ ESP off myself, but have experienced its action on both dry and wet roads.

John, don't know how this is possible. Are you saying there are "wet" sensors? I don't think so. I still think any braking action detected while ESP is off is due to drive wheel spin and the traction control component. Notice that ESP will correct vehicle tracking even when there are no "spinning" wheels -- it detects vehicle slip, not necessarily loss of drive wheel traction (i.e., spin).

ASR stands for Automatic Slip contRol. Don't ask me why its not ASC, that would make more sense to me also.

Color me totally confused
Turning off ESP (a) does nothing, (b) turns off some things or (c) turns off everything!
Anyway, I would like to know which setting allows more power at acceleration from dead stop. I don't want to smoke tires, but would like more acceleration power, if it is available

Jim, the answer is, turning off ESP via the dashboard switch disables only ESP, and not "regular" traction control. Check my earlier post in this thread where I described the difference between the two. That said, there should be no actual reduction in acceleration when those systems are in "monitor" mode. Only when the sensors detect a need for active traction control or ESP intervention should you notice a performance impact. Since drive wheel spin is corrected by traction control, turning off ESP will not prevent the braking of a wheel that "breaks loose". If you're talking about maximum acceleration from a stop where you don't want a "damper" if a wheel spins, I think you'd have to disable traction control via the "dyno" mode which is discussed elsewhere. Otherwise, I don't think you'll notice higher acceleration performance by switching off ESP or traction control. Just my $.03.

The best acceleration will be accomplished with ESP off. ESP will retard the timing, reduce the throttle and apply the rear brakes when wheel spin is sensed. With ESP off, the ASR will selectively apply the rear brakes to balance the torque between the wheels. In dyno-mode, you now have an open differental. All the torque will be applied to the wheel which loses traction first. On a dry, level surface this will almost always be the right rear, due to the direction of crankshaft rotation.
For best performance on dry surfaces, turn the ESP off. If you are a good enough driver, you will get the best performance with ESP off on wet surfaces, also.

Thed only way you are going to get more kick is to modify the engine. The cheapest way to get the occasional kick is to add nitrous.

Other than impressing the ignorant or destroying a set of tires one doesn't like, what is the point of a smoky burnout?
If you really want to do a smokey burnout with a stock 240, put the car in dyno-mode, lubricate the right rear tire with water or oil, stand on the brakes with your left foot and on the throttle with your right foot. Enjoy.

Perhaps I'm not making myself clear. I DON'T want to do a "smokey burnout", BUT I would like the power that would make them possible. As it is, my automatic c240 doesn't feel like it has enough power to spin out in the RAIN, from a dead stop! Now, if the ESP mode, of something like it, is actually restricting any additional power to the rear wheels, I'd like to know and experiment with it. Unfortunately, my wife has our c240 99% of the time, so I haven't had a chance to play with it, which is why I'm asking you all for the info
If this topis is specifically about the c230, then once again I wish there were either separate c230 and c240/320 forums or there were some clearer indication in either the title of posts that this is a c230 only mod

Jim, there is nothing restricting power to the rear wheels, unless the ESP/ASR senses too much wheelspin. I think the only way you can get a C240 to have the power to do burnouts is with a Kleemann supercharger or some other very expensive solution. In the long run, it would probably be cheaper to buy a C32.
