Hey all

I don't know how many of you have heard of this product, but I was asked to try out a prototype unit in my 09 Sedan.

Basically, for cars with electronic throttle control, this little device will cause the the throttle plate to open faster, therefore losing the typical lag that is normal with this type of throttle system.

My impressions so far is that definitely, the throttle is snappier, and I like that feeling of having instant throttle response like with cable actuated throttle plates. Mind you, it is clearly stated that this is not a power adder, but allows for more crisp throttle control.

Here's the US website (http://www.sprintboosterusa.com/), bearing in mind, the Cobalt is no listed yet since my car is the test bed and they are awaiting my report. )

I'll have a follow up report when I get more road time with the device installed.

Here is an explanation right from their website.

How does the Sprint Booster Work?

Sprint Booster is engineered to enhance the driving experience by providing increased acceleration time (eliminating delay) on drive-by-wire cars by continuously measuring and converting the digital signal and providing the ECM (Electronic Control Module) with a new and altered signal for much quicker response. Sprint Booster improves response, increases pedal input sensitivity and delivers more impressive off the line performance you can really feel.

Is the Sprint Booster easy to install?

It is a simple plug-n-play installation that takes just a few minutes and delivers instant response throughout the power band, making accelerating and rev matching incredibly more fun.

Is there a Sprint Booster available for my car?

Sprint Booster is application-specific and available for a number of popular high-performance makes and models.

When you put the pedal to the metal, nothing beats the roaring sound and feeling of instant acceleration!

Typical Device (Device will look different for each specific application)

 

I would say NO don't do it!

 

Gimmick?!?!

 

Its interesting but I don't trust sprint worth spit. SPRINT IS WORTH LESS THAN SPIT TO ME. I hate the company and you should stay the F away from this kind of crap. Tell them to stick to there crappy serivice and crappy cell phones. Why the hell would they be making car parts. Sprint sucks........

 

All this does is make the throttle body open more than its supposed to by increasing the voltage signal sent to the ecm, if you press the pedal down a 1/4 way the throttle body opens 1/2 way with this gimmick. If you want the same effect simply push the pedal down further.
If this cost maybe $30 it would be worth it, but its $300, you can get a tune for that much that actually makes the car faster.

 

I look at things this way, it's not costing me anything to test the part, so heck, why not give it a shot. What I do like, so far, is the faster throttle response. Mind you, if I can get that when I get a tune (down the road), the answer is pretty obvious for me.

Seems like IamtheCobaltian has already had an experience with Sprint Booster, care to describe your situation?

 

I think he has dealed with Sprint the cell phone service company. I really dont think this is at all the same company as that?

 

They are two totally different companies.

 

I would like a little better throttle response (1st 25% of the pedal travel is dead feeling to me) and I am tuned but if that device is $300 that is too expensive for what it does. I would be willing to pay maybe $100 for it but no more than that.

 

as some may know the delay in throttle response on the ss/tc sucks. you can watch your tps pid in hpt go wot and it take aprox. 500rpm for the throttle plate to reach 100%. thats a big deal when trying to spool a larger turbo.... I would buy one.

 

i agree the throttle response is horrible

 

Only one problem with this theory. The ECU controls the throttle. It takes inputs from several sensors. What ever you do to try to modify the throttle opening is going to reset the ECU back to default. Plus the Turbo delay, as small as it may be, is going to cancel out any benefit derived from this whatever. Non Turbo cars stand a better chance of getting any benefit from it.
JMHO!

 

This device apparently speeds up the response of the ECM in response to changing throttle position. Instead of it taking lets say 0.5 sec for the throttle blade to open 100% it will take less time. should help "lag" some. I Like cable operated throttle because instant response. This device makes the throttle more responsive like a cable operated one.

 

Ummm..not even close to the same company...Still wouldn't buy the product but don't confuse them with the awful phone service known as sprint.

 

My modified rear bumper should be finally be back on my car by the weekend, so I'll be doing some test drives and reporting back to our supplier regarding driveability.

 

so this supposedly gets rid of PE delay?

impossible.


the delay is a result of the ECU after the TPS

 

My tune changed the PE delay so it goes into PE mode sooner but I still have a dead feeling pedal especially out of boost. The first 25% is like there is no response and it drives me nuts. I hate electronic throttle.

 

Its actually been proven already on the solstice forum that this doesn't open the throttle any faster, it just opens it more during part throttle operation.
If you look at your hptuner logs you will see that the throttle body takes 1 full second to reach 100%(or 84% depending on the pid) after you floor it. The ecm still fully controls the throttle body no matter what signal the accelerator pedal/sprint booster sends it.
Im sure in the future we'll have access to the throttle body through hptuners.

 

Yes thank you for the clarification on that. They need to change there name so people don't get the two confused. I wouldn't want to be thought of as sprint the phone company. I literally thought this was a product from sprint the phone company as some kind of gimmic for there boost mobile BS.

 

I used the Sprint Booster in my C32 AMG, it made a world of a difference in terms of throttle response. But then again, the Cobalt feels worlds more responsive than the Benz did stock for stock.

 

you can change throttle sensitivity by playing with the TB area scalar... this mod is worthless... you can do the same thing it does by just pushing the gas pedal down further

 

Not on an LNF turbo you cannot unfortunately. We have no adjustability with HP tuners.

 

still not worth even $10 IMO

 

I noticed this lack of throttle response bad today, when I shifted from 2 - 3 I hit the gas, and for about a half a second to a full second, no engine RPM raise at all when at WOT below 3K. Sucks ass...anybody else notice this? Or is this just some freak of nature on my fuel delivery or pump?

 

Guess I'm lucky then, since I got the prototype in my car, and I have no delay in throttle response. I like it.
