From Sprint Booster site:
"Since 2000, INFINITI has replaced responsive cable throttle systems with the cheaper electronic versions. Unfortunately, they've robbed your INFINITI G37 of its performance. Sprint Booster not only corrects this problem, it actually improves your throttle response. It unlocks your G37's potential, creating a smoother, more powerful ride.

After you install Sprint Booster, you feel a huge difference the first time you hit the gas.

Sprint Booster gives you:
Quicker acceleration
Faster passing
Responsive uphill driving
Quicker gear changes
Easier rev matching"

Yes... $2 throttle cables are much more expensive than a stepper motor throttle body and electronic gas pedal.

I don't understand why anyone would want 100% throttle when only pushing the gas pedal ~50%. It must make it VERY difficult to drive in the snow/rain.
Is it really that hard to push the pedal all the way to the floor?

 

That isn't how throttle controllers work, look at the graphs on the previous page.

It remaps the whole pedel and there are various modes to choose from. Sure, you could map it to just devide the linear map in half as you're saying but none really do that, it isn't a linear transition like that.

And most of the time, when you want full throttle, you just push the peddle as you say. But that is rarely the case in most driving situations. A boosted mode for instance would allow more sensitivity in the midrange of the peddle, making for smaller and easier inputs to get that downshift initiated.

 

The graphs are marketing material and are not real.

Our pedal sensor ranges from 0 to 5 volts. The first "Super Sprint" graphs shows an "over boosts" (more than 5 volts) which is not possible.



I have driven a car with this on it. The first 50% of pedal give you 100% throttle. It feels so wrong to be at half throttle, floor it and nothing happens.

Bottom line: If you like this buy it, but I think it is a silly product, with no value. I can push my pedal to the floor if I need to.

 

Just so you know, it's not showing it over volting, it's showing you where the boost throttle map is in relation to the stock at some peddle travel distance. I don't know where you saw it as over voltage...

Like I said, people use these for different things, no harm in having choices on how the peddle feels. A guy in here uses one merely becuase the take off from red lights were too harsh.

And not everyone is trying to have to push the peddle all the way to the floor just to downshift the 7at for a simple passing maneuver. It is terribly exhausting and wasteful to do that just to get if to downshift. This product allows you to achieve that downshift quicker since you don't have to mash the gas to the floor which gives you a bit more control over the whole process of accelerating.

But yeah, re evaluate those graphs. It's not just "marketing" it's how those maps act in relation to the stock map. The voltage is not going over or under 5 and 0 respectively.

"[ECO Mode]

There are 3 ECO Mode options. Throttle response time will delay compared to factory throttle simulating the accelerator pedal being pressed gently which can result in fuel economic efficiency due to decreased initial load from the output of the accelerator pedal, in some cases can reduce fuel consumption by up to 10%. The ECO Mode can also be used to desensitize vehicles with abrupt throttle response from the factory, as seen on some vehicles such as the Toyota Tundra Truck.


[Lo-Throttle Mode]

Throttle response will delay from normal mode based upon throttle pedal percentage range. Throttle will react to how the user presses on the pedal between idle-to-full throttle range.


[Boost Mode]

Throttle response time will become quicker and results in improved accelerator pedal feel. Returns to normal mode once pedal is pressed to fully open throttle.


[Hi-Throttle Mode]

Improved throttle response based on throttle percentage range, in this mode throttle will respond as if
depressing the pedal in full throttle. Returns to normal mode once pedal is pressed to fully open throttle."

 

Since I am happy with my car's throttle response, I guess I don't see a need for a device that remaps the pedal response.

Their marketing is very good. I like how they use the word "boosted" to give the impression you are getting more of something.
