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
1+

I am all for it, and in someways, I think i know away where we can make this happen. I am traveling to Cali late this month, if there are any west coasters willing to track this thing, or hit the drag strip, i will bring my module.

This product will make it so that you don't have to hold the brake and throttle at the same time to launch. Mitsubishi will save thousands of warranty $$ if everyone installed this. We will also no longer look stupid when taking off from a red light! The 1/4 mile time will be close to 1 second quicker due to that lag time being removed (dont expect to see a change if you are doing the brake/throttle launch). No more limp mode!

having someone test it would be awesome . I plan too but wont be able till the end of may. If no one else does before then, then ill have the data at that point at least.

That's impossible, to launch the car you need to add throttle. Whether you're holding the throttle halfway down or a third of the way down, you need to add the same amount of throttle to get the same kind of launch.

Without taking sides, I think there is some confusion here. The argument is not that it changes the amount of throttle needed for a launch. As I read it, the point is that the device shortens the delay between when the pedal is at full throttle and when the engine is at full throttle, lessening the "lag" between pedal input and response. The throttle is being opened faster basically.

Therefore, there is the perception that to have quick launch, you don't need to brake-boost. However, it shouldn't make a (practical) timed difference unless you are measuring from the time someone says Go! because that time would include the lag between Go! and throttle open. If you are measuring from when the car starts moving, it shouldn't matter because it will only move when the throttle is physical opened which will not change.

Is this serious?

The device can't shorten that delay based on how it works. It acts in between the throttle position sensor and the ECU. It doesn't directly sense how far the throttle has moved, it merely acts to amplify the signal from the sensor to the ECU. WOT is WOT.

amby ive been nice, but stfu please. enough is enough. You don't understand your *** from a whole in the ground when it relates the the facts im trying to make you understand, so just quit before you look like and even bigger ***. Even the mods noted u should **** off.

What the point here is... WITH NO ****ING THROTTLE AT THE LINE THE CAR WITH THE SPRINT BOOSTER WILL HAVE A BETTER 60 FOOT THEN THE CAR WITHOUT BECAUSE AS SOON AS THE LIGHT CHANGES AND THE DRIVER PUTS HIS FOOT ON THE GAS, THE BOOSTER REMOVES THE LAG WE EXPERIENCE NORMALLY.

Its not a hard ****ing concept kid. Jesus christ

It's hole in the ground, generally if you're going to use that phrase to try to insult someone, it's best to spell the word correctly.
OK, I'll explain this easier, how can a car accelerate off the line without any throttle input? If there truly was zero throttle, the car would not move. Now then, what you're saying is that when you get on the throttle, the car accelerates faster. How is this possible without adding power or lightness? Take your subjective views out of the equation secondchance and just think about it for a moment. Ignore what you think you feel and analyze the situation critically. How can a product which acts to amplify the throttle signal have the affects you claim it does?
This article gives a nice breakdown of what the Sprint Booster actually does. http://www.crosslake.net/~dbipes/spr...intBooster.pdf

That was exactly how I was going to put it. I don't know why amby doesn't get that... Is amplifying the throttle signal the only thing that SB does?? If you don't know that for sure can't say anything to oppose that.

People who have the ralliart knows how painful that lag is. It's a nice way to change that. I would do it too if it didnt cost 300+

Then the graph posted is a misrepresentation because it shows throttle vs. time. I interpret that graph as someone stomping the pedal and, without the device, the signal is max in 0.4sec and with it, 0.3 sec, meaning the throttle (at the engine) is opened faster with the device.

After reading that paper, it's hard to argue with what it really does.

Arguments aside I think it's a great product if it does what secondchance is stating. It would be nice to pass the granny car next to me for once at a red light when I have to make a turn real quick.
Not everyone takes our ralliarts to the track to race. Some people like to have fun driving experiences and this sounds like a great way to make that happen.

Seriously, Can you just end the insults and get back to something with more substance. Not just Amby but everyone. I think everyone needs to take a step back and drop the arm chair sniping.

I think if you have something new to add. do so , but lets not run over the same points. Generally even i am eager for a nice debate, but if people on both sides of an argument cant see eye to eye and respect the other. Then its just not worth directing comments at them.

SB is a product like anything else, try it, or dont. Know one has a gun to to your head. end of story

According to someone who took some data, yes that's all it does. I wasn't aware of that.

For what it's worth, I don't notice any lag (other than turbo ), certainly not 1 second worth.
