I am sorry but we will just have to agree to disagree on this point, everyone has a perception of any event and your perception of this product and my perception of the product are totally opposite and that is ok. I do however believe (my perception) I know when I run out of throttle and it isn't at 1/2 to 2/3. I will however submit this, after reading all the posts on many Sprint Booster threads all but a couple are SB fans and would not take theirs off and in my books that makes it a successful product.

PAULW (aka The CHUMP)

 

For your daily driving thrills, the sprint booster is leaps and bounds better than the throttle reset. I would say that a throttle reset does about 10% of the improvement of the sprint booster. With my sprint booster, it is almost impossible to accelerate moderately without practice. Under light pedal movement, it feels like my car has 800 horses. Accidental tire slippage under what "feels like" light throttle is common.

 

True that! I drove this Toyota Corolla (stock), and when I lightly touch the throttle, I get accidental tire slippage too! It's only got 120 hp, but it feels like 300! Unfortunately, when I add more gas (going from 10% to 80% of the pedal), I don't get anymore power.

 

As an engineer I'm more interested in what exactly makes it tick. I used to build a lot of home brew computer projects, electronic synthesizer projects, etc., so I enjoy the builder/tinkering hobby aspect of electronics. It might well be possible to improve upon the design (manual or otherwise programmed adjustments would be a welcome addition in my book, perhaps you don't want 2/3 throttle equal to WOT, or?).

Food for thought.

 

Are there any ECU reprograms to "enhance" the drive by wire experience ?

 

+1. I thought someone already took it apart? It would be pretty sad if it some transforms the voltage signal, and no more, which is what the paper suggests, but that doesn't jive with the seller's claims of "linearizing" the throttle. Is there anything else it could change besides the actual voltage? maybe the ramp rate of the signal?

 

I'm pretty sure that's ALL it does. Read my previous post?

 

Sorry, I read it, and forgot about it. No offense yo you, it's an ADD thing. Thanks for the reminder.

With that in mind, how is it "linearizing" (or linearizing the perception of) the throttle at low inputs? I find that I get too little power, then too much power, at low inputs. Would the SB just make it feel like too much power, then WAY too much power, with the same inputs? I think that's where I'm missing its effect.

 

I agree, being an "aluminum" tube it may even be warmer. But the increased volumn seems to help, even with no other changes.
But to actually gain a cooler air temp, insulation would be needed for sure.

 

Good questions and thought line. The best products are usually invented by one and a "tinkerer" takes it to the next level and hopefully does so with the approval of the inventor. I have had my ECU remapped and at least the place that did mine could not correct the lag and I have not heard of any that can. I work in the heavy truck business and we have used drive by wire for some time so I understand what all is done by the computer with the information from the TPS, it isn't just throttle control.
Now having said that if we could add an old style throttle linkage and move the TPS from the foot pedal to the engine then the computer and I would both be happy!

 

Post #42. SRT6Tulsa sums it up pretty well. It does take some getting used to. I really used to be frustrated by the lethargic way it would accelerate, say, from a traffic light. A slow build-up like "The Perfect Storm". Now I want to be the first in line so I don't rear-end the fella' in front of me.

It takes practice, but that's a GOOD thing!

 

Got it... I'm the other way around... I feel like I don't have enough travel in the pedal, and that, even w/o the SB, the throttle ramps up too quickly with too little input. I don't need a Sprint Booster... I need a Sprint Buster...

 

I am no expert at running quarter miles and had never done it until the last time we had a private track day.
My first 11 runs were all 15.01 to 15.18 with the stock intake.
Then I installed the Needswing CAI and my next 11 runs were all in the high 14's and my best time was 14.78.

I do have a sprint booster and I do think it opens the throttle faster than even putting it to the floor without one.
If it is only worth $2 or not I like it and that is what really matters here.

 

sounds simple
crack one open and post up the pics include pics of both ends of the cable.

 

Here is a "Sprint Booster technical white paper".

 

We've all seen this study countless times. The argument remains !

Is it worth the 275 bucks..........................Probably not !
Is it worth the grin factor..........................Oh hell yeah !

We can just agree to disagree and be on with it.

Thats just my Dos Centavos

 

MMMMMMMMMMMMM..

 

Well said and exactly to the point.

 

if this is the only thing this product does then i will offer a limit supply of special edition Crossfire Extreme II drive boots that offer an adjustable 20lb weight over the right big toe . 275.00 a set

 

Just so everyone knows the sprintbooster does not make your car faster. other than that enjoy
