Yes, the right way where science and reason stand above hype and personal feelings.

 

ya just like Democracy for Individuals and Free Markets like how it is in the

 

evo_soul you are the Tom Cruise of mechanics.

Tom Cruise believes that after reading a couple of books, he knows more about medicine and how to cure something better than doctors with diplomas and years of hands on practice.

A small amount of knowledge can cause people to think they are more expert than they really are. Alexander Pope 1688 - 1744

This is not an insult, just an observation.

 

i would love to fly a F14 but I am no Tom Cruise, and I like doing research and trying stuff. nothing more

The president is not expected to be an expert, but to surround himself with experts to get the best advise when the need arises.
lol I am no president, it was a quote from somewhere just cant remember from whom lol sigh

 

This thread makes my head hurt.

Just popping in to note that I'm watching, in case people get all worked up and think about flaming.

 

Please take a stab at these basic questions.


this sir......is brilliant

also the rest of your post is pretty much spot on.


Evo_Soul I'm not attacking you personally, so don't take what i say personally. My issue is the product itself, and right now you're the only one standing up for it and answering questions. If it where anyone else I'd be acting the exact same way. I just wanna post that in case anyone gets the wrong idea behind my comments.

 

Dont take personal offense to anything, and I have no problem with you speaking your mind. You have come off as a straight shooter and thats a good thing I will try to answer your questions by keeping it super brief but from my personal experience and from what I understand of the device.


Please take a stab at these basic questions.


1. Does the sprint booster work by increasing the signal from your gas pedal to make the ECU think you're giving more gas than you are?
yes

SHORT: Yes but I do not think the gain is as simple as straight amplification of the throttle curve for example 2X or X4.

LONG: Based on how the car reacts, (and forgive the use of abitrary estimate numbers to describe) the start out acceleration seems normal, a little bit of pedal will give you the same little bit of power, same as without. Where I notice a difference is in the middle. it seems very easy to control the cars attitude in the 40 to 70 % pedal range. I never really venture beyond that since that would give me too much power



2. How is this any different that just pressing down on the gas more yourself?
it isn't

Short: If you car is stock, you must continuously, step further and further down until you get the right type of response needed. and Pressing 100% WOT is too much power.

LONG: A stock car has this goal posting effect where its very hard to gauge where in the throttle range the right amount of power is. So I want a semi brisk accelleration, my instinct as a every day driver would shoot for 60%, nope thats not it, 70%, nope, 80% ok there it is just right. When you over shoot thou, then your needle will go from 3000 RPM and unleash it all the way up to 5000RPM which is much much. When I operate Sprint booster, its much easier to get the throttle control I want. I can apply the pedal say in one 10% or 20% stroke and accurately get the right amount of power, this is the simplest way to explain it. If I had to speculate on where the sensitivity is for this unit I would say it would be in the middle portion of the throttle controller. I no longer have to plant and replant my foot.

3. How does the ECU/TCU learn a more aggressive driving style by the sprint booster increasing the output of the acceleration signal. vs. the driver pressing the gas harder?
it doesn't. You pressing the gas harder is the exact same as the SB increasing the pedal signal

SHORT: I kinda answered that above

LONG: ECU and TCU are equally in control of the car, In some ways when you look at it, the TCU is monitoring all the factors collected by the ECU and this is where it factors in those hard coded rules that make up the TCU Logic basis. Then the User input is factored in. I find pressing harder ineffective because the foot travel for constant normal driving is bother some. You would have to plat your foot further. When you drive our CVT (unmodified) you just get use to the under performance. which is sad.

4. Can you teach the ECU/TCU the same aggressive driving style by being more aggressive with the gas pedal?
yes

SHORT: YES, to a large degree with heavier foot plants you can let your car know you mean business. but its hard to keep the CVT in the LOW MIVEC High TQ RPM profile.

LONG: Second point to add to above, I dont think I drive my car all that aggressive, I simply want it to respond in a predicable manner when i need it. One last way I could maybe convey this idea to you is, say there was a test like Matching the car speed of a car next to you. Say they were going to pass you. I can instinctively press the throttle and know without second guessing how much I need to press in order to get what the amount of acceleration I want. And I can do it all within the low Mivec RPM threshold.

One final comment about driving our cars (stock unmodified) When your accelerating, say from a dead stop and you just want to go.I swear by this, I can accelerate and it doesnt matter if I step at 30 or 40 maybe 50ish in pedal %. The RPM needle always 99% of the time always levels off at 2400-2500 RPM. You can ask this question to anyone. It actually feels like the car is preventing you from going over that hump. I have in my previous posts speculated why that happens, but the fact is, thats the way it is. With sprint booster, its much easier to push thru the 2500RPM mark I can give myself a steady 3000RPM accell with little effort, I can drop it down easy, give it gas again to push above. Its just way easier.

All I can say is the CVT version module words well, but I do know that these are all tuned differently so I would assume the manual 5 speed version is calibrated differently. I suspect that each cars throttle curve is different. on the first page of this thread amby posted a picture of the throttle reaching 100% very soon. another version of that graph shows the throttle opening up early and returning to the standard curve. I think it would be safe to assume that there is not a one unit fits all Sprint booster, but I would assume that they are calibrated for a different curve depending on the car. I have attatched an example. Its speculation but it would seem logical because my car goes no where near full throttle at about 75%. As an estimate as I said before I beleive the curive in the middle would appropartely be the place of an increase because that is the area of greats effect on the controller. I have a few other theories about the unit itself but I am not an eletrical engineer and that would be speculation. If you would like to hear it I will continue but i think I again turned it into a long post.

sorry

 

Who cares - SPRINT BOOSTER WORKS - i had some $300 to spare why not. I can afford it. All this rant... GEEEEZZZZ. And i'm going to buy one for my BENZ to. THE END.

YES!!!!!!!!!!! ITS ALIVE!!!!!!!!!!!!!!!! ITS ALIVE!!!!!!!!!!!!!!!! ITS ALIVE!!!!!!!!!!!!!!!!

 

haha I like the enthusiasm, but that doesn't really help us. People here are trying to figure out how it works, and what the result of that action is. by just saying "it works", you aren't taking a side in this matter. It's the same as saying "i like it", where it would be better to say why. We all know that it "works" in that it does something, but the point of contention is whether is actually improves performance or just feel.

Amby, I agree on most points with the exception of one in particular. Fried chicken, corn, mashed potatoes, and gravy in a bowl is a fantastic idea. it is even better when gobs of bbq sauce are stirred in and it becomes a serum of fast food delight.

 

And that sure turned out well .

 

YOU GUYS NEED HELP????? Instead of listening to whether it works or not --WHY NOT EXPERIENCE IT???? Like what I have suggested to others before or to other bashers i've met all my life -- You get more knowledge from experience --RATHER THAN READING AND READING AND READING -- and coz of that you think you know it all???? DAMN I FINISHED COMPUTER PROGRAMMING AND I THOUGHT I KNEW IT ALL TILL I GOT MY FIRST HANDS-ON EXPERIENCE -- ITS NOT GOING TO HELP YOU GUYS FIND OUT UNLESS -- YOU TRY IT. This thing comes with 30 days money back guarantee. I know I know some of you are not fortunate enough to go running to a local store that carries it. DID YOU LEARN HOW TO DRIVE STICK BY READING THE MANUAL OR BY ACTUALLY TRYING IT??? C'mon folks you guys can read and read and read it all here from someone who thinks they knew it all but NEVER EVEN TRIED IT and to stubborn to try it and now trying to convince the population that ITS BS. Hehehehe.. I laugh at this kind of people -- they sound like those preachers here Downtown that the end is coming and we must repent -- You know what i'm going to enjoy life go on and keep experiencing things I want to experience and not let some BOOKWORM sway me off what i'm interested on doing. DID YOU LEARN HOW TO FIX CARS BY JUST READING THE BOOKS OR BEING AN APPRENTICE????? WHAT i'm trying to tell you guys is Let your own judgement guide you by actually being there and seeing/experiencing something in action -- AND THAT'S HOW LIFE WORKS. SPRINT BOOSTER BS??? Did you ry it or you just read it???? Try it and post it here what you think. Once you actually have tried it -- THE STAGE IS YOURS.

 

1. It is more or less irrelevant whether the amplification is linear or not, it is still simply amplifying the throttle signal in order to "trick" the ECU into believing that you have pressed the pedal more than you actually have, nothing more.
2. That goal posting effect would still be present, if it's a matter of the throttle input remaining under a certain ceiling, that ceiling isn't going anywhere. What you are seeing is the amplification, while at 60% you would normally be below that ceiling, with the SB at 60% you are actually applying a higher amount of throttle (as interpreted by the ECU) thus that ceiling is avoided. It is the same as planting your foot.
3. More or less answered above.
4. If you don't drive aggressively (as you say), this idea that the SB allows for a more aggressive map is irrelevant anyways. You are simply flooring the car, that's it.
As you state over and over again (in less words sometimes), this product just allows you to hit WOT easier, that's it.

 

I have answered this exact question about a billion times (of which I think 999,999 were for you) but here goes another time. The "why not try it?" argument is flawed. First off, why would we want to try a product that is not logically sound? If I gave you a blue pill and told you to "just try it", would you? No, you'd damn well want to know what it does. Same applies here, I'm not going to spend 300$ (even if there's a money back guarantee) for a product that is sketchy at best. Second off, there's the problem of the placebo effect, if I spent the money, I'd expect gains. In fact, I'd be looking for gains even there weren't any there. This is why actual data is absolutely necessary. I myself have fallen for this effect, I was so sure that I had gained good power from the bolt-ons I had on my Lancer. Well guess what, I gained jack-all. Third off, if we all tried it and hated it, people would claim we were biased, lied, etc. The only way people would accept our decision is if we absolutely loved it. The rest of your argument is seriously flawed. Automotive mechanics isn't in the stone age anymore, cars are more technologically advanced than ever and research is key. Cars are based on sound scientific processes, not trial and error. If the science is lacking, the product sucks, it's that simple. Your comparison to driving stick makes no sense since driving a manual car is a skill, the Spring Booster is clearly not. Also, last time I checked, people go to school to become a mechanic, they're not just handed a wrench and let loose.

 

So, from your perspective, I should just not knock on anything until I pay money and try it? of course, that makes perfect sense. Why don't we just all try everything instead of researching it and making informed decisions BEFORE WE SPEND OUR MONEY.

if someone tells me something about a product (ie, it's great! it works! you should try it!), I'm not going to buy it until I research it. This sprint booster SOUNDS like those weight loss pills you can buy from the 3am infomercials. They may make you feel better about yourself, but they aren't going to really help you loose much weight. I know that already, because it sounds like a scam and everyone knows it is. This sprint booster product deserves the same scrutiny, there's just no data to back up the claim that it gives me GAINS. I could care less about how touchy each person likes their peddle, I don't spend 300 dollars so I can FEEL faster.

I still am at a loss, why is this so complicated? How good something feels to what performance gains it gives. That's the issue, why can't it be addressed by the proponents of this product?

 

mtags24 just by reading their site it should be pretty clear to people what it does and doesn't do. Unless people keep ignoring the FAQ and the Why it works page, which clearly state that you will not have any gain other than having the car think that you're pushing down the accelerator 25% more. Which will be gone once you get used to pressing down on the accelerator less not to drive too sporty and get tickets or waste fuel (or not to smash into cars trying to park in an out).

But sadly people got into this loop of contradicting the manufacturer and start claiming other type of gains when using it. The product works, it does what the company claimed, it's just silly that people need it when you can do the same with your foot. The problem emerged when people started posting that it will does near miracles if you have a CVT tranny. It turned into a debate like Stephen Hawking v.s. The Pope: Evolution or Creation chapter 666.

I believe that people who understand the concept will see straight through it and most likely will turn away from it. Others will buy it in hopes that it will be the miracle cure (or at least a Band-Aid) to their slow CVT problem.

We can't tell people what to do, most of us wasted way over 300$ on junk that doesn't do much for our car, but we like it anyway. Others want to race while having 300 pounds of junk installed in and on their cars, yet they want to make sure they have less than ¼ tank of fuel when going to the track. We are silly people doing lots of stupid things.

Anyway... There is no problem with somebody advertising a new product, long as there are no extra claims besides what the manufacturer claimed that the product does. I bet that the company would claim a whole lot more if it would do more, that's just more sales for them.
