Instal the Sprintbooster W204





If there's something with my car, the first thing i do is remove the sprintbooster... 2 minutes work....
since it's installed onto the pedal its not hard to guess it is to do with altering the throttle sensitivity, in other words i guess it's the same as pressing the pedal alot faster with some of you mentioned, it's just that when you didn't have to press this hard you have the feeling of "it is more responsive"
this is like tightenning the throttle cable in japanese cars

not worth the invest for me as i seek something more real
I drive a 2009 C350 and I don't have that "lag" of which you speak. I actually have to be gentle upon take off or I will snap my passengers neck
. Maybe because the car is new or maybe MB took care of it
.Can anybody confirm this.
will you guys buy the sprint booster if it around $150? I would!! let's try to talk the seller down to that price!!!

First - Sorry if my english is bad, but here I dont use in my day.
Congratulations for all.
This forum is a FIRST CLASS and they are fantastics.
Here in Brazil, MB is a most expensive car.
In Dollar here one C Klass 200k - US$ 100.000,00.
Yes, I know, t's insane!
But I love and buy...
This part, SPRINTBOOSTER, working?
Have a "real result"?
And the LAG, have another solution?
Tks & Bst Rgrds.

I think Sprintbooster does work. But it makes the car more responsive/quicker, but no more powerful/faster. I don't know if that makes sense.
People on another thread is talking about update some kind of ECU program that will get rid of this LAG problem. We are still waiting to hear from the guy to give us the program code so we can update it in the dealer.
So, good luck.

to my understanding this SB is no trick to the ECU hence no performance gain
it tricks the gas pedal to make it think ur pressing more than u actually did, in other words is same as pressing ur gas pedal harder and thats all
i buy into upgrading ECU programming story more, or to tune the ecu if the benz ecu is programmable
你是台灣人嗎?
But I agree with pressing the pedal harder.
I have noticed with my wife's C240 that if I press the pedal halfway to the floor when taking off from a stop, it performs much better than a typical 'gradual' press. If I press all the way to the floor it actually responds worse.
Maybe people with a 'lag' (on automatic transmission cars at least) can try the halfway method and see if it eliminates the problem. It works for me.

I hope the exterior of your car is not as filthy as the interior. Do you live on a farm?

sprintbooster what?I have a Pathfinder and similarly, it feels fast off the line...faster than my c350, but my C350 would destroy it in all aspects. The C-class just has a smoother power delivery and a wider and flatter torque curve. Most SUVs have more low-end torque which gives the initial sensation of acceleration. My Pathfinder then quickly looses steam in the upper RPM range. I had a E46 M3 previously which never really felt fast off the line even compared to the C350. It had a flat torque curve and good horsepower in the high RPM range making it deceptively faster (much faster) than the C350.

Here, the problem is a HEAVY TAX.

In some times I will post the pictures with my Star.
Congratulations!

HEAVY TAX in Netherlands , making C180K a lot expensive... . more expensive than a BMW as well.
Anyway , about the ECU update and ( 5 gear) auto Tranny update , the LAG is stil there but its now lot less than before and gear shifts are much smoother now. in C mode or in S mode.
They should easily find an ECU update if you go to dealer. If you have 7 gear auto tranny then there will be no update for the tranny i think.

Hey people, say to me:
-"The TAX over CARS is a good idea to create a new topic?"
Tks4All.
Wondering whether you, and others who have SB, have any audio noise since installing the SB? When I set the audio input to AUX (but dont play any audio) it is more noticable. The seller is willing to provide an exchange but I just wanted to see whether others SB users are experiencing the same issue.

i know, i know, it wasnt the best time to make the pictures.... I clean my car every week, so dont worry, it wont happen again.
