I didn't say I didn't believe you. I said I didn't agree based on what I have read. READING and experiencing are two different things. I'm interested in how the Sprintbooster works with a mostly stock setup, myself.

 

It's all good I wasn't directing it toward you. All in general.. I did have a sprint booster on a stock acura I had. You can program it. To hit WOT at 1/2 throttle. Which really is not good for nothing but drag racing for people who can't use throttle management well. Or if you just want a touchie throtle response. I removed it after a few days.

 

I understand that the ECU programmers comtroll TBW (Throttle by Wire) but I think the Sprint Booster works outside of the realm of the ECU. It sounds like it simply boosts the electronic signal that your skinny pedal sends to the ECU and thus fools the ECU into thinking that you are pressing the skinny pedal harder than you actually are (i.e. you get a quicker response time).

 

Be the guinea pig and give it a try.

 

This is exactly how the Sprintbooster rep explained it to me when I called. He said that the Jeep could even receive PCM updates from the dealer with it installed, because it did not change PCM programming one iota. That's actually why I chimed in, because I had talked with them. It sounds like from that, that they would work in conjunction.

 

^^ You guys might be right according to sprint booster it works with anything. But from my experience it would not work with any EMS I have every used and with others in the FI world. I copied and pasted this. I underlined the points of interest.

"Sprint Booster makes your car's throttle respond faster to your foot. As a result, your gas pedal actually achieves a full throttle response 25% sooner than the stock configuration. Even if you have a 'sport' button, Sprint Booster will quicken the throttle response time. By making the throttle respond faster to your input, you will feel as though your car has more muscle than it really does!

• Sprint Booster does not increase Horsepower.

• Sprint Booster does not reduce your 0-60mph times.

• Sprint Booster DOES make your car 'FEEL' faster.

• Sprint Booster is not for everyone.

How It Works

Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street.

Sprint Booster simply modifies the throttle signal between the accelerator pedal and the throttle body. Big deal right? Keep in mind, this is the same concept as the 'throttle pulley' modification on cable based throttle systems - which was very popular in it's time. It doesn't add horsepower, but makes the throttle more sensitive and makes the car 'feel' faster.

It doesn't matter if you have a Sport Mode, ECU software, or 'Chip' on your car, Sprint Booster works independently of other modifications. It simply makes the throttle more sensitive, making the car 'feel' faster."

Even if it does. I'm not paying over 300 bucks for something that just makes the JK feel faster. That's just plan dumb.

Edit: I would say it just manipulates the volts going to the throttle body.

 

I wonder what the fail safe mode for this thing is? If it fails can it trick the system into thinking you want full throttle when you don't?

I would like to see the FMEA for the design of this product. Also how do they know the fault tolerance characteristics for the ECU control strategy.

 

Just received this Email from Sprint booster.

"I keep hearing this from Superchips, and even called there tech dept. to tell them we do not compete, but compliment each other. We have hundreds of people who run Superchips and our Sprint Booster without any issues. We have driven with and without the Superchips and although they claim to make the DBW better, and it does make it better no question, the difference a SB makes is still night and day difference. In fact many people say that the SB made a much bigger difference then the Superchips, but together it worked excellent."

 

Did he also say that they were going to drop the price by $200?

 

Well, if the price will come down a bit on the Sprintbooster, I may just have to try one. My Lord...it only really does one thing in comparison to many other programmers that cost the same and do much more.
