How Sprint Boosters Work?

How exactly does a Sprint Booster Work?

In the old days, the interaction between your pedal pressure and your throttle was immediate. You pressed on the pedal and the throttle cable opens your throttle instantly. You had a direct connection between pedal and throttle.

Today however, your accelerator pedal is connected to a sensor that sends a signal to the ECU (engine control unit). The ECU is connected to a servomotor that operates the throttle in proportion to the input from the accelerator pedal. And because your ECU is “governed”, you get a hesitation called “pedal lag.”

But with a Sprint Booster, when you turn it on, it actually remaps the curve that the pedal is producing giving your throttle instant response.

So, What Exactly Does the Sprint Booster Do?

The short answer is, it is an amplifier, boosting the accelerator pedal sensor signal by about 30% which makes the accelerator pedal about 30% more sensitive.

What Exactly Does the ECU Do?

The ECU does a lot of things.

For example it may:
reduce the pedal sensitivity when driving in reverse.
close the throttle based upon wheel spin, or loss of traction, even if the accelerator pedal is not moved.
limit throttle response in the case of a fault, such as engine overheating.
alter the response of the throttle to the accelerator adapting to the driving style.

It’s a smart tool, but it sure is a limit on pedal accuracy.

Just installed this on my Tundra and it is quite impressive. Install took less than 5 min. The out of the box settings were perfect for my driving preferences and hands down the best upgrade for the money. The compact size is exactly what I was looking for and nicely compliments the dash. The driving experience I was missing; power on demand.

I installed one in my 2019 4Runner and am completely happy with it. It now responds exactly like it should have from the factory. I set it in Sport 5 and to me it's perfect there. I removed the control and put it in the console in case I want to change it but I doubt I'll ever need to.

GUYS i have a question. i installed this on my Fiesta mk7 and after a couple of rides, a message showed up saying "engine malfunction, service now". what do i do?

how exactly is a device that's amplifying the throttle pedal signal reducing the response time? it sounds like the same thing could be gained by just... pushing the pedal down more, as your graph shows at 1:10

Does it open tje throttle body more or just faster?

[hansturpyn]

Do you trick the pid controller in the ecu by giving of a fast spike in the signal when pushing in the gas? So that the pid controller reacts to the faster change in throttle-signal thus reducing the lag in the output?

Is this better than getting a tune on a dyno?

Are you still in business? I can't get any response from your company!

So it doesn’t make your vehicle quicker 0-60?

I just installed mine on a Mazda 3. To be honest, you still feel a slight pedal lag, to be honest, I couldn’t feel much of a difference. Or maybe I felt like I was going to get more torque when slamming the pedal.

you can just achieved the same goal by putting a ground to your throttle body and Battery
