just installed the new sprint booster on the clk 550 and i feel like this car finally woke up!!!

its nuts...in sports more and on the RED setting this thing kicks back like a race car

do u guys normally leave the sprint booster on for daily driving? this thing is addicting

i got it at tdotperformance...a canadian website for 290 shipped cheapest i could find online

 

Yeah........Sprint Boooster is very very addicting. I can't drive my car without it anymore. I bought the same version before I even bought my Slk55. I like both modes (green & red) but red is my favor and I leave it on at all time.

 

I stills havent installed mine. Cant wait!!

 

Please understand that the sprintbooster is nothing but an amplifier. All it does is make the throttle more sensitive by opening the throttle plate by more than the pedal sensor input for a given travel. i.e. the throttle is wide open at about 60% of pedal travel depending on setting. Thus the last 40% of pedal travel does nothing. Accelerating harder does the same thing. If you like the feeling - Great!

The SB does not reduce throttle lag or latency. That is built into the ECU & can only be corrected in the ECU. It does not increase performance.

 

That's what I thought. Just gotta mash that gas pedal

 

Interesting

 

Let not get into it again because there are thousand of posts about it already. Those that bought one, LOVE IT !!! Just let em enjoy it.

 

yeah seriously....you are talking to veterans man...we KNOW ALREADY happy holidays

 

The sprint booster increases RELATIVE performance not absolute performance....its not fair to say there are no performance gains with a sprint booster...cuz from 0-60 i'll take out another clk 550

 

I'm not going to start again - but that is quite impossible. I was messing with Sprintboosters ever since they came to market.

Enjoy your placebo effect. I have no problem with people saying they enjoy it as long as they do not make technically inept claims. Go well!

BTW - also read the excellent white paper on the subject.

 

No one yet make any technically incept claims.........so what with your post? You're on a mission for what ever the reason. Here's mo re post from you on the subject.

The sprint booster issue comes up from time to time & I choose to comment on the past. We do our level best to give accurate info on this forum & yes all of us slip up from time to time. A sprint booster will not improve 0 to 60 acceleration. I will prove this to anybody that feels like coughing up for a dyno test on a well sorted Schenk or similar chassis dyno in a climate controlled dyno room.

I'm cool - no problem at all

 

im sorry i even started this thread...lol

 

i bought this product knowing it wouldn't increase hp...300 bux to have the car shift and feel like a sports car is worth it

 

So does everyone that bought one. I'm not sure to why he feel the need to tell us these and that about it. Just enjoy man

 

im up next for one =)

 

Well I found Glyn post to be very useful. Thanks for the info Glyn!

 

It's still good to know the technical side, thanks for the info Glyn

 

I have one not installed yet,, but would like someone to go to the track and get at least 3 runs without and 3 runs with and let us know (if the 60' is faster because of faster throttle response) then the 1/4 will be faster. I am going to do the test myself but would like to see a few more test done with different cars,, most dyno runs are for wide open hp,, not how the revs gets there.
I will be doing my test in Jan, at PBIR. jim

 

midnight lets race =)

 

some tips on installing....you will need to remove the roof trim above the gas pedal to get access, the roof trim doesn't remove completely because it is stuck on the part where the hood access handle is located.after you have access u will remove the plug right behind the gas paddle, will need to push on both sides and pull out
the toughest part is getting to push on both sides of the plug

after its removes just connect the booster into place...the roof trim hides all the wires. and the power button is nicely placed near the key hole area of the dash

its a freakin awesome toy

 

No..this is not a good test because of the instant throttle response you actually will lose track more from a dead start.

 

Yup.....the new three modes is awesome !!! You can instantly test out the stock mode(off) and Race mode (red) and the response is like day-n-night!!

 

The latency in the transmission TCU remains a constant. If a kick down is required it takes even longer.
The latency in the ECU remains a constant.

I can understand that some like greater acceleration for a given throttle input until it hits WOT at partial pedal movement & then does nothing.

I think the largest success of the sprint booster is relieving purchasers of $300 for a 50 cent dual channel op amp. Oh yes - and it now has a switch and two resistors to vary sensitivity.

A Benz "fly by wire" throttle has a backup channel from the pedal hall sensor to the ECU for safety purposes hence the requirement for two channels..

 

Nice explanation
