I'm sure it's just flashed onto an EPROM in the ECU - I'm equally sure that the tuning guys do it as part of an ECU tune amongst other things.

Sprint Booster Works!
I have had the sprint booster on C320 03 for over 1 year.
got it on EBAY forabout $285 and worth every penny.
No Joke, takes only 5 minutes and do not see the small black box that goe inside under the gas pedal.
simply take out 1 bolt and the gas pedal comes out and you see wire connector, Hook inline and re-install.
reset your ESC using the reset method explained on site.
and see what happens! You only push your foot 1/4" to go instead of 2-3 inches and the response is FAST. No More Sluggish in passing or taking off from green light.
Also IT IS SAFE in parking lots somehow. is what I was worried about. But you relearn how to drive. only th pressure of your foot is all you need for normal driving, and very little pressure on the peddle.
It is More Aggressive, so if your an old man, wanting that take off slow and gradual this is not for you. keep what you got, however IF YOU WANT NEW LIFE like a new car,
the sprint booster has worked Great over 1 year with no issues.

Unbelievable that people are still fooled by this thing. He even understands that it's changing the gas pedal distance, but he still thinks it's making his car more responsive. THAT IS ALL IT DOES! Your car is NOT more responsive. It's been proven, it's a fact, and the reasoning is obvious.

You're forgetting. It's compensating. Since your wallet is much lighter, your leg won't be as heavy - so the sprintbooster allows you not to have to press down on the gas so hard.
Jeez.

It does not increase HP in any way at all - even the company that makes it admits that in their documentation.
It's also important to note that it DOES NOT reduce the throttle lag either (or I would have bought one by now). It simply amplifies the signal coming from your gas pedal. You push the pedal down 1/4 of the way and the sprint booster alters the signal, telling your ECU that you have actually pushed the pedal down 1/2 of the way (those numbers are just for arguments sake). I hope that helps explain it. That is *ALL* that the sprint booster does. Once you're pushing the pedal 3/4 of the way down it's telling the engine "FULL THROTTLE! THE PEDAL IS DOWN ALL THE WAY!" but it is not. When you actually push the pedal further down past 3/4 it does *NOTHING* because you are already at full throttle, so the last 3/4 of your pedal is now useless, you might as well put a brick under it.

Only people who do not have a Sprintbooster are the ones who are making a case against it. Those with will will attest to the positive changes it has made to the way the vehicle feels and the throttle response changes. However it is achieve, however deep into the technical and engineering tidbits one wants to get, the end result is the same: The car is tons more fun to drive and no amounts of "pressing the pedal farther" will make up for what the Sprintbooster does.
White paper or not, the seat of your pants and your own experience with it is what will truly speak for themselves.
I just hate to see such a great product (which won an award for "Best New Product" at SEMA 2009 http://www.modified.com/news/modp-09...ema/index.html) get thrown under the bus.
I also want to remind those of you who have read what I had written when I became a sponsor here, and to those of you who have no idea who I am yet, that I will only stand behind a product that I can truly endorse because I either own it or have owned it and have had nothing but a positive experience with.

Maybe even with that being true, you feel that it is a great product and it makes your ride more enjoyable. I just wish people would be honest about what this thing does and does not do. I respect your own personal opinion, but false statements about a product really irk me.

Ok so pushing the gas pedal down more will do the same. Ok let's go with that. Can you push the gas pedal faster than what the sprintbooster will do? No you can't. Don't say you can. Anyone who has experienced the springbooster will tell you the same. If I could do what the SB does by just pressing the pedal harder, then they wouldn't be in business.
On the same token, with a manual transmission, you will be able to rev match easier than you could without it. A similar feat can be achieved by ECU tuning. My Audi S4 6spd had a Revo tune, and with it off, my throttle was just like an Automatic Mercedes. With the Revo tune on, it behaved as with the SB I now have. While I could still rev match without Revo tune on, it made it much easier with on.
So like I said, don't be looking at numbers, scientifical points of view, and simply take it for what it is: a great product.
Let me ask you acr2001 and LILBENZ230, have you owned a Sprintbooster before? If not, I suggest you stop the propaganda immediately. And in the event that you DID own one, did you own it for more than say a week's worth of driving? Because if not, I don't buy your argument that you think merely pressing the pedal down farther renders the same end result.

nice plug
oh and that $300 can be put towards an ecu tune that will not only do the same thing, but will also net you a few ponies as well.

Yes YOU CAN push the pedal down just as fast. That was *PROVEN* in the white paper which included *SCIENTIFIC EVIDENCE*. Please end this illogical argument. Those who argue for the sprint booster are proven wrong every time you look at it from any engineering perspective.
How can you possibly stand behind a product with a statement like this:
"don't be looking at numbers, scientifical points of view" ?!
This is like trying to sell me a new engine but telling me I wont have to worry about any of the specs because it will just feel like it's a fast engine - the HP numbers lie

And I believe a good ECU tune can also actually reduce the throttle lag (the throttle lag is generated in the ECU - NOT in the signal generated at the gas pedal - which is all the sprint booster can alter) - a legitimate gain rather than losing the last 3/4 of your pedal travel!

Anyway, it's your money, you spend it as you see fit. To me and countless others, the Sprintbooster was a mod that was undeniably worthwhile.
Did you read the white paper? It has *SCIENTIFIC FACTS* presented. GRAPHS. - and all of them make perfect sense if you have any sort of electrical engineering background. It's not possible for the sprint booster to increase the pedal / throttle response, just based on WHERE it is installed in the electrical circuit. You are suggesting it can do what is physically impossible based on its design. Do you understand how the electronic throttle system in a Benz works? If you look into that in detail you will understand why it's impossible for the sprint booster to meet these claims.

That we called you out on promoting what is essentially a signal amplifier that will relieve someone of $300 for absolutely no performance gains is not spreading propaganda. The reverse is true. If anything, the promotion of this product and it's "benefits" is propaganda.
I'll continue to do my best to talk people out of buying a product that is virtually useless. $300 is better spent on something that actually does something useful.
Edit:
Nice try on the "paper racer" argument. The horsepower figures of 500hp and 350hp that you used in said hypothetical race would be engine ratings done through testing and considered fact. Sprintbooster testing (and fact) says it is worthless. End of argument.

This is a direct quote from the sprintbooster official website: (http://www.sprintboostersales.com/whyitworks.cfm)
Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street.
Sprint Booster simply modifies the throttle signal between the accelerator pedal and the throttle body. Big deal right? Keep in mind, this is the same concept as the 'throttle pulley' modification on cable based throttle systems - which was very popular in it's time. It doesn't add horsepower, but makes the throttle more sensitive and makes the car 'feel' faster.

I like you.. LOL we think alike. Nothing irritates me more than someone who parades opinion as fact. Or make brazen statements that they can't possibly back-up with anything. To make this relevant to this particular discussion, my car could use a $300 detail job right now much more than it would need something to amplify the signal of the throttle. Whether I press it 1/2 way down or all the way, the end result is the same - it's fairly slow. Amplifying the signal of my C230's throttle would be akin to winning a 10x multiplier on a slot machine where your prize amount was 0. What's 10 times 0? Oh damn.. I would need at least 20 times 0! /sarcasm.
