Let's face it, owning a car and not tweaking it, no matter how nice it is is just plain boring.

My 'theme' this time with the CLK is a Sleeper :D So mods will be performance orientated (plenty planned :D ), and the exterior will look like 'just another Merc on the road' .....

Starting today, I fitted a Sprint Booster. This clever little device is quite an innovation without one having to pay significantly more for a one off throttle re-map. It's made in Greece, and it's an add on device that mimics the 'Sport' button we are familiar with on an E46 M3. The difference is very noticable ;)

HERE (http://www.youtube.com/watch?v=j-Skix-0CZc) is a video explaining what it is (in Greek ...... lol :D )


Drive-by-wire throttle is easy to tune. Sprint Booster increases throttle exponential, ie. the throttle butterfly opens more at any given gas pedal position except near wide open throttle. Cars with automatic gearboxes, it also shortens the lag between throttle movement and kick down. And on a Mercedes Benz, this is the most noticable aspect. Overall, the whole car comes alive! The throttle feels so much more responsive :cool:


This is what it looks like (pics taken from another forum, and standard installation on all modern Mercedea Benz with drive-by-wire).

The throttle pedal assembly has to be taken out to fit this mod. On Mercs, it involves loosening a nut, followed by pulling the assembly towards you and then downwards.

Unplug the switch that connects to the throttle assembly and fit the Sprint Booster in between the throttle assembly and the main connector.

Reverse the disembly steps and you're done. 10 mins job :cool:


Here's a graph depicting what the Sprint Booster does.

Another video (http://www.youtube.com/watch?v=JmtIOiUj1XQ&feature=related) showing what is does .... :D


Overall for less than £150, a mod that does what it says on the tin. I recommend the Sprint Booster to anyone. Cars with automatic transmission boxes you'll notice the effect the most.

looking good nick,.

will be interested to see whether a merc is more difficult to mod yourself compared to an M3 et al....i keep trying to get my Dad to mod his SL55 AMg, starting with a big loud exhaust system, but he's not having none of it at the moment

we'll see though!

cheers and enjoy

Nice simple mod there Nick and excellent write up. Is there any point doing this on the M3 as they already have the sport button ?

I have the Sprintbooster on my 330i Auto - Brilliant mod.

Took a couple of days to get used to it but I wouldn't be without it now - It transformed the pickup and acceleration.

I read a very interesting thread about sprint boosters earlier today, just trying to find it again now.

Next Sat :D ......... watch this space ;)



Just went out for a spin again, driving in manual mode. The 2007 7G-Tronic gearbox comes with another mode on top of the usual cruise 'C' and sports 'S' mode. The full manual 'M' mode keeps the torque converter locked, ala Alpina's Switchtronic. Damn it's fun! So much more responsive :D

Wondering if the sprint booster will work with my already remapped ecu from ESS... Stop moding it's addictive!

Nice mod Nick. Will have to seriously think about this for mine.

Of course. But IMO it's not significantly worse, probably 2-3MPG less.

Give them a call to check compatibility. They have increased their range significantly since July last year.

Has anyone fitted this to a 2000 323ci with a remap? If so was there a big difference.

I think the main objective is throttle response Sonu. It doesnt phsically increase any BHP etc. it just makes the response quicker when you whack that pedal, you get an instant reaction rather than a slugish few second delay on the revs.

hi i have one fitted to a remapped 325ci,i had the car remapped about a month and then fitted the sprint booster and you notice a difference alright, the only issue you might have is the throttle pedal might not be the same as the cars from 01 forward
