Jangy,
The kick down switch is TRUELY just a button that has nothing connected to it. It might be different in the 03-04's. I think u drive an 05. The kick down switch is acutally the movement in the gas pedal going pass a certain point.
You seem very passionate about how the sprint booster works and how its not a mod but for a person who has and ECU done up by Kleeman, I love the sprint booster. The ECU remapping doesn't do much about the lag time. If I want to take the jerkyness away, i drive in C mode. STill very responsive and drives likes like a differnt animal. Even without the sprint booster, I try to smash the gas pedal, there is still a little bit of lag time. Sprint booster gets rid of that lag time..... anyways, I understand that you are not a fan of the sprint booster, but major of people who actually have and use the sprint booster everyday, I can safely assume that we are very happy with it....

I'm still doubtful that the kick down switch does nothing. It's been proven in the Porsche 997TT Tip that if you depress the accelerator all the way down, it will result in worse 1/4mi time than if you don't step on it all the way, and it is equipped with a similar kick down switch.

Interestingly enough, another issue I have with the sprintbooster and all the ECU tuners is why would they not program in an ideal throttle curve? I hate how incomplete and vague all the tuners are with their probgrams. All we (the customers) want to know is how much does it cost and how many HP it gives, but that doesn't translate into faster lap times.
Different strokes for different folks. Reality is that the sprintbooster is a cheap mod that has no irreversible detriment to the car, so i do not mind people geting it. I just find it funny that everyone is trying to get their cars to do the opposite of what I am. I want MORE modulation of the throttle not less.

You don't take the button out, but it's attached to the pedal and the entire assembly has to come out when you install it. You can then examine it. It's a thin piece of plastic and once it's off you can see there's nothing attached to the button. No wires, it sits there all by itself. A socket wrench and 5 minutes and you can see it for yourself.

I've installed a S.B. on my ML63 and absolutly love it, but I'm not sure I would do it on a S.C. 55 motor. My E55 had traction problems stock from the factory. To add a S.B. might make it more twitchy yet.
An E63 would probably benefit more. Less torque down low where the Sprintbooster shines.
It really works well on my AWD ML63. 4 other ML63 owners installed units within the last weeks and all love it.
You may also try Stealthauto for acquiring a S.B. He's becoming the USA distributor. (Also a MBworld sponsor)

right now there is confusion on the kickdown button the E55. Some say it is a dummy button, which wouldn't do jack to your TB valve. i don't know that it should. i assumed it was for TCU more.

Not yet. I been at work all day. i'll do it and tell. What I can't figure out is why the OEM part has the wire plugs on it if you guys say there are no wires running up to it (from behind). I know the front doesn't have connections.

The kickdown switch works on my 07, so everyone who's complaining about it just isn't driving hard enough.
If you drive aggressively, the car will downshift hard without the kickdown pressed...BUT it will not hold the lower gear if you ease off the gas. With the kickdown slammed, it will still hold the lower gear for a good 3-4 seconds, even after completely getting off the gas. It serves a purpose in my car.
The only thing I can think of is some of you guys just don't drive hard enough, and your cars are in "pu$$y mode"
As for SprintBooster, it's a GREAT mod for those of you who are terrified of the gas pedal. Don't EVER consider that a real mod though, since it only makes a difference on the driver, not the car.

Say what you will, I agree it not a performance mod. I just prefer my performance a the top of the pedal instead of the bottom.

I dont think the discussion is around the kick down button and if it works or not. I believe the discussion is around if the kick down button actually is a button that triggers the down shifting or if its a dummy switch. In taking my accellerator (sp?) assembly apart I found that the switch in MY car has no wires attached to it. I believe that the button is there to mark a certain point in the accellerator pedal. As it goes past that point, it will automatically kick down a gear or red line.
Seconly, the sprint booster does modify your vehicle in some way, shape or form. So I am not sure why you wouldnt call it a mod(ification). Again just my opinion.
