Please share your result. I really like to know if it works good on modded car. From my guess, it would work cause it lies to your brain. It is like you have a heavier foot and step more gas. For max out power, it should not improve anything.

 

I don't think you are reading the chart as it was intended.
I think that chart presumes that you stomp the pedal as fast as possible. 0.4 seconds sounds like hitting the gas pedal fast. So the difference is that the sprint booster gets you to every point between no throttle and WOT faster, that's all. very simple system and it should work if that is what you want. It is amplification. And I am sure it works. It is a less sensitive throttle system. I have yet to hear anyone who has gotten one complain that it does not work. If it is an amplifier, I agree that it is not worth $300. And it looks like that is all it does. But if no one is making an alternative for lots less, they have the corner on the market.

 

You're reading it as they intended you to read it. Without data showing the actual pedal position, you have made an assumption of what the chart is, and assumed the the pedal was pressed instantaneously at the 0 time marker. However, that is not what's going on, but you have fallen for the marketing ploy.

 

jprice, you are probably right as this white paper indicates. Regardless, it is a simple electronic device that should not cost more than $30-$40.

 

This is not entirely correct. The reason why sprint booster is extremely difficult to describe in technical terms is because its much dynamics than people give it credit for. Again, and we drive this home as to what Sprint Booster does.

Sprint Booster is engineered to enhance the driving experience by providing improved acceleration by eliminating the delay inherent in drive-by-wire accelerator technology. This is accomplished by continuously measuring and converting the digital signal while providing the ECU (Electronic Control Module) with a new and altered signal for much quicker throttle response. The actual device contains electronic circuitry that is installed between the accelerator pedal and the ECU in vehicles equipped with electronic throttle control.

We speak to drivers all over the world, from different walks of life, and ask them one thing. What is it you want out of your car? In today’s modern cars one of the biggest complaints is throttle lag. It doesn’t matter how you look at it, all “Drive By Wire” cars have at least some degree lag. In some cars it is very pronounced. And to some people, any lag what so ever is completely unacceptable. Simply put, the lag gets in the way of what they want to do. This is why we put the technology to work and work to eliminate this lag.
To a Daily Driver, it puts excitement back into the daily drive. Many describe it like driving a new car, or at the very least bringing the driver back to the day the first bought the car.
To the Race Track Driver, it is more about control. Having exact and accurate throttle response can mean the difference between winning and losing, and communicating with the car that you want to power now, not later. Even a millisecond can be too late.
The simplest analogy for this is, communication is everything. In today’s world if things aren’t instant, people can’t be bothered. When it comes to throttle control it’s the same exact thing. If you are not getting the power when and where you want it, why bother.
There are so many types of drivers out there that it is impossible to cover the all. Anyone can step on the pedal and mash the gas, but where is the control, where is the precision. One of the biggest misconceptions about our product is, “am I going to burn more fuel?” And the short answer is no. “Why is that?” Give the driver better control, and they will start to use the throttle more effectively. Overtaking a car on the highway doesn't have to be as savage as mashing your foot or a guessing game with the throttle. Sprint Booster doesn't replace the fact that you have 0 to 100% throttle range to play with. It will allow you to use this range more effectively without lag, and this come back to the fact that it is constantly monitoring your pedal, how much it has traveled, how fast the pedal traveled and it dynamically sends the correct signal to the ECU. The right amount of power you want. If your expectation is to utilize 60% power, you get 60% power. You want 80%, you get 80%, if you want 100%, you get 100%. The difference Sprint Booster makes is “You get that power instantly. Without the lag!!!”

Here at Sprint Booster USA, the master distributor for North America, we believe that vehicle owners are experts on their own cars. They know what their car can and cannot do. And in an age where today’s cars have electronic throttle controllers (DBW) they realize that it’s no longer their foot that is in control of throttle response like with the throttle cable. Now it is now all in the hands of the ECU (a computer) and that computer is what will ultimately determine the response you get. Our product allows car owners to take back throttle control. And every day there are dozens, hundreds, possibly thousands that try our product and realize that it is worth the investment.
The product speaks for itself, people buy it, and generally fall in love with it from the time they first touch the pedal.
Bringing this dialog full circle... To use a chart, no matter how simple or complicated, still doesn’t do the product justice. You have to understand, it’s almost impossible to capture on a chart the dynamic nature of what sprint booster does. We have said it before and we will say it again.

Sprint Booster is engineered to enhance the driving experience by providing improved acceleration by eliminating the delay inherent in drive-by-wire accelerator technology. This is accomplished by continuously measuring and converting the digital signal while providing the ECU (Electronic Control Module) with a new and altered signal for much quicker throttle response. The actual device contains electronic circuitry that is installed between the accelerator pedal and the ECU in vehicles equipped with electronic throttle control.

The one of the key thing to understand Sprint Booster's function is the angular speed (how fast the pedal changes angles ) The angular speed is also referred in the patent application.

It’s very easy to nit-pick points and go back and forth of what sprint booster does. But, at the end of the day those who try it buy it. And would buy it again! We offer a plug and play install that has a driver up and running in minutes possibly seconds depending on the application. With the new selectable version, a driver can turn sprint booster on and off at will to double check what net effect sprint booster has on his or her car. And, if at the end of 30 days the customer isn’t happy. Send the Unit back. It is that simple.

For anyone else still on the fence and need to do further research, do a good search, find first hand experiences either in the media or on the forums.

good examples.

Are you just copying/pasting from the Sprint Booster sales / marketing info? This is not entirely accurate, and you have failed to actually address the concerns brought up in this thread.

First of all, the signal between the pedal and the ECU (and in and out of a Sprint Booster) is an analog signal (0-5v dc), NOT digital. The 'constantly monitoring' means constantly amplifying, no?

Secondly, the sprint booster does NOT reduce any DBW delay, as it is in place outside of the loop in which that would occur, which is between the motronic routines/tables, and the physical throttle body itself. There is NO delay between the pedal and the ECU in a 100% stock setup. Analog signal, and potentiometer.

Since this paragraph in itself is completely inaccurate, what else can we or can we not trust? It's not hard to describe what Sprint Booster does??... It's actually quite easy. It's not hard to create a graph that makes sense out of what it does (input and output voltage in relation to actual pedal position). The problem is the company constantly provides meaningless or incomplete data, and refers only to user reviews to say the product technically does what it says it does. The only technical review available is the whitepaper, which DOES show that it's a DC Voltage amplifier.

No mystery, not complicated. But Sprint Booster makes sales out of confusion and misdirection, so of course they'll continue down that path.

 

If your argument is that there is no DBW delay, then we really cant find common ground to debate the issues. We created a product to address throttle lag. We designed it, we patented it, and over the past few years refined our product. We continue to do so to this very day. We are committed to improving upon our product to meet the demands of the market who overwhelmingly feel the delay created by Drive By Wire systems.

We do not attempt to misdirect anyone. We have made product that has been reviewed thousands of times over by the general public and by we respected media and journalist panels. So far, we are very satisfied with what our customers say.

There is a group buy underway now, with customers trying sprint booster for the first time.

I think you're failing to understand my argument. I never said that there is no DBW delay or lag.

Let's make this simple:

Do you agree or not agree that there is no lag between the ECU (not including the ECU) and the pedal? (0-5vDC and potentiometer)

Do you agree or not agree that "DBW lag" is introduced between the ECU (including the ECU) and the throttle plate?

 

I think his argument is that any delay attributable to DBW occurs between the ECU and the throttle, not between the pedal and the ECU, which is where your product operates.

Clearly, your product can send a signal to the ECU that tells it the pedal is fully depressed before it is fully depressed. But that's hardly a DBW issue.

 

fyi lol

 

Sprinter boosters are fantastic cheap easy mod worth everyone of the 300 bucks they cost

 

Just imagine what the new Sprint Booster V3 is like.. Wow! I'm sure there's a sale going on too..
