It's not modifying the throttle curve, that's programmed into the ECU. It's changing the way it amplifies the signal or at least claiming to change the way it amplifies the signal based on RPM or more likely throttle position. Given that the graph is in seconds though, it's hard to interpret since generally speaking, throttle position should be independent of time. As I've said before, it lets you achieve a specific throttle position a fraction of a second faster, if that's worth 300$ to you, go nuts. Frankly I'd rather spend 300$ on mods that actually made the car faster, not ones that make the work of my right foot marginally easier or inspire me to yell "VTEC!!!!!" out the window while drifting to Toyko time.

 

you misinterpreted what i meant as beneficial. The booster allowed me to launch harder with less stress on the tranny from a stand still as it doesn't have that hesitation you normally get with the car unless your in the 15 psi range off the line. that in itself is beneficial. And it doesn't surprise me that you would rather look at the negatives then the truth. It does make the car more responsive and attentive at low rpms, period, regardless of what they claim or you think. As i stated it isn't for everyone, but it has its benefits. I also consider you trying to speak so educated about a product you haven't tried out, more specifically on this plate form kinda foolish. For once, you truly don't know bro, so just leave the topic to the discussion and inquiry for those who have questions and concerns.

Thanks.

 

That doesn't make sense though given how the product works. How can a product who's sole method of operation is to essentially increase the sensitivity of the throttle pedal, allow you to launch harder with less stress on the transmission?
Wait, so now you're going to dispute what Sprint Booster says about their own product? I'm not denying that it works, it certainly does what it advertises to do but what it advertises to do isn't to increase power, isn't to make the car accelerate faster (which would require the input of power or the reduction of weight), it's simply to make the car feel faster.
Why is "if you haven't tried it, you can't talk bro" the fall back position? I also haven't tried cocaine, heroine, jumping off a tall building, the Tornado, etc. but using a bit of logic and reasoning, I can deduce what the results of those things will be. Along the same lines, it's not hard to deduce what the Sprint Booster is and is not capable of given how it works and what the manufacturer itself states.

 

i said specifically on this plateform amby. Please stop using generalized arguments on a product review. It would be one thing to own the car and have an understanding of the day to day hesitation the SST gives us, but you don't drive and if you have, its very little, lets be honest.

Anyone with a white hat and boxers that ride up knows what the product does or is designed too do if they have 5 minutes to read or try it. The fact it is inline on the throttle sensor gives it away as it is.

The REASON i saw it allows you to launch with less stress is very simple. I thought i made it clear, but since i didn't and you couldnt deduce what i was trying to speak about, i'll break it down for you.

Normal launch in the ralliart with little or no throttle yields a wicked awesome hesitation. Anyone who owns the car will agree its annoying. Once installed, the car yes you guessed it DIDNT have the hesitation, and came off the line with little or no throttle alot smoother and quicker.

Now with that fact hopefully being understood i'll continue.

By removing the hesitation (which we have normally bypassed via a hard break boost on the line) you no longer need to put AS MUCH or in some cases any of the added stress of said boost stand on the transmission. Relative theory would suggest the lack of time lost to the hesitation would allow for a quicker 60 ft time, which will translate into a better 1/4 mile time, and depending on the situation can effect the trap speed as well.

Am i saying that the same 60ft times arent attainable without the sprint booster? Am i saying it will reduce even those who break boost hard? no not at all. What i am saying, which i feel is essential in a community that has the tranny failure plague is simple. The product yields fairly similar response off the line, with less stress on our million dollar baby transmission.

 

sounds good to me.

 

How the SB works isn't going to change from application to application. Whether it's on a Miata, WRX, Lancer, Ralliart, whatever, it still works by amplifying the throttle signal such that the throttle pedal is effectively made to be more sensitive, or to put it another way, the degree to which the throttle opens increases relative to the amount that the throttle pedal moves. This product does not interact with the ECU or the TCU anymore than the stock throttle pedal does thus it cannot make any changes in how the transmission behaves outside of what was possible with the stock system.
What you're noticing is simply due to the throttle pedal being more sensitive. While normally you may have required a pedal position of lets say a 1/4 to get the launch you required, you now only require an 1/8 pedal position thereby giving the illusion that the car is faster because you didn't press the pedal as much to get the same level of acceleration. Logically, the same amount of stress is being put on the transmission as the ECU is still interpreting that pedal position as a 1/4, the boost levels are the same and thus the strain is the same.
The difference is response time under race conditions would be almost too small to register. Unless it takes you seconds to go WOT, you wouldn't notice it in a 1/4 mile drag or any measure of acceleration where you're going WOT as quickly as possible.
This is why I think Sprint Booster is pure snake oil, it seems to make normally very rational people say irrational and illogical things. Hell, I'm jealous of the Sprint Booster people because I'm sure they'll make a lot of money off this product.

 

i never mentioned it changes its application from car to car. you are simply only reading what you need to see to justify your response. For someone who uses theory and physics a lot you are quick to forget that changing the constant variable that being the CAR with yield different results. One could argue that the booster is the constant viable as well, fine, but by changing the applicant you allow for variable change and open the window for difference and patterns.

The simple fact is that the tranny and the interaction it has with the throttle on car A isn't the same as the transmission and subsequent interaction it has with its throttle on car b, which will theoretically post varying and unique results.

Now really amby, i'm not stupid, so please don't attempt to patronize me, this is the last place we should battle smarts and intellect. With that said i agree with most everything you say outside of the stubborn and wrong stance you have. regardless of what you THINK, in this car, with this transmission, and the TCU tables the way they are, the booster ALLOWS ( however u need to explain ) for a quicker response and less stress on the transmission on a launch. Your argument that its simply less throttle is invalid. It doesn't matter how much throttle you use once the light turns, the car WILL STILL HESITATE, unless its break boosted. With the booster inline, it DOESN'T .

Use all the deduced information you want my friend, what i state is fact. 2 of us in Calgary and one person who tested it on an evo in the states have all felt the same changes. Until they are proven WRONG with a valid in car comparison and test, they are FACT.

 

The car won't change it anymore than basic physics will change from car to car (as someone has previously argued on here). For the most part, DBW systems work the same whether it's a Mazda system, a Mitsubishi system or a Subaru system. If they were dramatically different, Sprint Booster would not be able to have as many applications as they do without charging substantially more for the product.
The way in which the throttle pedal interacts with the transmission is the same, in that it doesn't, at least not directly. The throttle signal logically goes to the ECU or TCU first before it produces any change in the transmission, like a shift lets say. Due to this, the behaviour is logically the same regardless of whether the SB is involved or not since the SB asks merely to take a signal from the throttle pedal, amplify it and send it off to the ECU.
Again, how can a product that acts to amplify the throttle signal, as Sprint Booster themselves say it does, produce a unique result in regards to launching the car? What you're trying to argue goes against what the manufacturer states the product does. Even the graphs evo_soul posted make this very clear.
Once again, I'm not saying the product doesn't do as it's advertised, it does that very well but what you and others have tried to argue go well outside it's abilities given what it does.

 

a gross assumption based off data and literature you yourself have argued the validity of.

Enough is enough though, you are too thick to listen, and the same old act of the same old play you like to re write so often bores me.

Leave the topic for those who have interest.

 

Actually I'm basing what I say on what people who have taken the SB apart have noticed in terms of how it actually works (complete with testing) and the information posted on their website.
Naturally I must be too thick to listen, it is much easier to say that than actually address my points. This thread seems oddly familiar to the current health care topic.

 

oh geeze... here we go..

 

Nah, it looks like it's done.

 

everyone knows where you stand on this subject. no point in talking about it

 

It's nice to reiterate it every once in a while when people start attributing illogical things to a little black box that amplifies the throttle signal. What's next, it cured their grandma of cancer and stopped rampaging Toyotas?

 

i think the biggest thing we need here is actual data. i think, as mentioned before, there is a 3-way switch you can use with their new module? so very simple, take the car to a track, turn sb off, from dead stand-still no brake-torque, stomp on pedal as hard as possible and let the car do all the shifting in sport mode. then repeat procedure with sb turned on and compare results.

if anything, i think one of the biggest points secondchace was trying to make, which is pretty legit for our major transmission concern, is that you can achieve near-launch or brake-torque like results from the throttle, without actually having to do so and thus eliminating the need to sit and spin clutches at the line causing excessive heat and premature wear on the trans.

graphs and computer numbers are never tamper-proof, but hard evidence is hard to deny... lets see some track time slips
