Sprint Booster anyone?

[eTiMaGo]

I've heard nothing but good reviews for these things, and my friend has one in his BMW, its basically an electronic module which overdrives the signals sent by the DBW system. It makes the throttle much more responsive and reduces the slight lag we all hate.

But, they don't make them for any Toyotas... I've just emailed them to ask if they ever plan to, so let's keep our fingers crossed!

[Ranggarn]

Thomas.. the pioneer = D

[eTiMaGo]

hahah sure, buy me an oscilloscope and a degree in electronic engineering and I could become a pioneer :laugh:

[Ran Kizama]

I'd be interested. :smile:

[joey1320]

how is the signal altered in order to make it "quicker"?
all it is is 1 or 2 potentiometers in the thorttle pedal that lets the throttle body know how to move the butterfly. how slow could that be???

[spkrman]

lol.

yesterday I was thinking about how the DBW system could be modded for this purpose... and I was thinking it cant be that difficult.

[eco]

Im in.

[Galavoxx]

I would love one of these assuming the price is not too cost prohibitive.

[ChinoCharles]

There is definitely a little bit of lag there. For example, when rev matching in my car I have to blip the gas and hope I nailed it, because by the time the engine responds to my foot I'm already letting off the clutch. Granted I'm comfortable enough in the car now to know within a few hundred RPM how much I gave her, but still, it would be nice if it was instantaneous. I'm listening Thomas. :biggrin:

[ricktoyota73]

Just saw the SprintBooster in the latest Import Tuner. They do list one for the Yaris now. http://www.sprintboosterusa.com/c-198-toyota.aspx
$329...ouch.
Anybody try one of these?

[PHXDEMON]

It better suck and fuck me for 330 bucks :laugh:

[whooppee777]

so it does the same thing as the blitz throttle controller?

[cleong]

Yes, but it is not adjustable. From what I understand there are two models, the "mild" and "aggressive", so you buy the chip that suits you.

You'd be disappointed to find that $330 buys you a little plastic plug that weighs next to nothing. But it definitely changes the throttle response, fooling the ECU into thinking you're stepping on your accelerator than you really are.

[eTiMaGo]

yes, now Blitz and Pivot have similar devices with several degrees of adjustability (even economy modes that reduce throttle response), far more interesting!

[revoturbo]

I already use this sprint booster (mild) on my turbo yaris..

faster respond But fuel also very fast respond he he he..
but my wife told me feel different "too fast" for low RPM-hi respond

they works like positive exponential curve on Radio control car
available in mild & aggressive. install only in minutes on all drive by wire car..
the price IDR 3.000.000 (expensive)

[marcus]

so weird my friend just told me about this last night....so weird..eerie!

or for free you could just push the gas pedal sooner ;)

:laughabove: got a valid piont there:bow: :burnrubber:

[PETERPOOP]

How much does the blitz controller run for?

[blacksandiegovitz]

How much does the blitz controller run for?

About $300-350

[*MAD DOG*]

Would be good if there was a blutooth program that could do this via your mobile phone. If anyone goes into production, remember me. :wink:

:laughabove: got a valid piont there:bow: :burnrubber:

:laughabove: Valid and piont should not be used in the same sentance..... :bow: :burnrubber:

For those that dunno wtf i'm on about, the word he was searching for was probably point.

[revoturbo]

or for free you could just push the gas pedal sooner ;)

yes RIGHT !!! :biggrin:

[bearda]

or for free you could just push the gas pedal sooner ;)

It's not even so much an issue of hitting the pedal sooner, but hitting it harder. My understanding is that all this thing does is adjust it so when you have your accelerator in a position that used to give you 40% throttle, it gives you something like 50%. You could do the same thing by just moving your foot further.

Both products are essentially a crutch for those who are hesitant to really gas it.

[BLAZINBLUEVITZ]

a crutch for those who are hesitant to really gas it.

so i guess this product would prove useless to me then......

[marcus]

is it true that our throttle only opens 80% even with peday to the metal play.. does this or blitz helps to open it in full??

that doesn't sound likely.

and once you pass a certain rpm and throttle percentage, the car goes into open loop anyway.. ever notice that if you push the pedal almost floored, the car is just as fast as floored? that's because your car's in open loop and therefore Dumping fuel at a preset rate, ignoring o2 sensor, etc etc

[2manywheels]

There is a retail shop here in town that sells the Sprint product.
If you pay upfront for it, you can try it for 14days and return it if it doesn't work to your satisfaction.

Fellah got back to me. $330 CND.
said it is pretty simple to install.

[marcus]

good luck let us know if it works.

From what I've heard and read they are incredible! They do make a Sprint Booster for the Yaris now and it's under 300 dollars. It has 3 settings. Factory setting where it cant be detected by the dealership. Green mode where it eliminates lag while increasing throttle response. Red mode greatly increases throttle responsiveness but can feel jerky during shifts. Some prefer using the automatic transmission model on a manual car because it reduces the jerky feeling. Both versions are compatible with the manual cars from what I've read. I'm getting one for my Porsche Cayman 2.9l manual and I'll be getting one for the Yaris LB automatic too. It has a great return policy too.

[birdman]

Update. After installing one on my Yaris first it acts like a hot hatch. I paid 289 bucks with free shipping and these things are a bargain! People who install these keep them whether they are in a Mercedes, Porsche or a Yaris. Even though there is a 30 day return policy I cant imagine anyone doing that.

They don't increase horse power but they remove the lag making access to the power you already have much quicker which translates into a very noticeable improvement in performance. I haven't found a Honda Fit that can keep up with me. I couldn't say that before installing it. If top Porsche race tuners love them then perhaps more Yaris owners would too. That's why Sprint Booster designed one for the Yaris too. Even though I love my Porsche Cayman I can't imagine ever selling the Yaris. I want to see if it will outlast me. Doing the math it just might.

Glad to hear real world experience on this. I am in the process of changing to a cable TB rather than docking with DVW at all anymore.

I'm curious how this compares to the 1zz TB mod with the manifold port. The throttle response with those 2 mods are a big increase.

Just curious as to whether it's worth $300 USD...

[yarisugi]

...or buy my lightly used Pivot Throttle Controller (http://www.yarisworld.com/forums/showthread.php?t=55628)? :biggrin:

You can't really compare them. They both have different functions.

The 1ZZ TB & manifold port you have, provides better airflow to your engine, which in turn will create more HP and torque. Unfortunatly, it will still have the operational delay that most DBW cars have.

The sprint booster, on the other hand, does not increase hoursepower, or torque it just allows the TB to open without any delay.

Ultimatly they both translate into faster 0-60 times.

Now, my question for everyone is, if we were to drag race 2 Yarii, one with the 1zz TB and ported manifold, and the other with the Sprint Booster unit, which one do you think would win?

[tmontague]

I have to disagree on that one. The 1zz tb mod alone increases throttle response as the butterfly valve opens ☓ amount per depression of the pedal, more air flow in coming in due to the large diameter when compared to the 1nz TB.

The sprint booster does nothing to speed up the electrical signal as that would be a much more invasive thing to do.

All it does is simply as voltage to the signal making the ECU think you are pushing the pedal down further. Hence why the last 25-30% of your pedal throw is useless w/ the sprint booster.

People have taken apart the SB's and they are very simple pieces. If you aren't shy about punching the throttle you can do what a SB does yourself. People like them because they allow you to be shy with the pedal and have the car go like you're flooring it.

The SB will not improve 0-60 times as per their website. It will only reduce that milisecond it takes to push the pedal down to the floor instead of only 70%

A car w/ a 1zz tb w/ a port matched diameter manifold would win as the car w/ just the SB had no actual gains in engine performance, just the sensation of being so.

That being said, since Toyota's are virtually untunable, you don't get to experience the full benefit of intake a exhaust mods so the difference wouldn't be very drastic.

Just my $0.02

[Rigaud]

Sprint booster makes the response time (lag) faster and the 1zz TB swap even intake manifold are not at all the same. Yes it responds quicker but due to more air mass being accessible. The lag is still there, it's electrical and totally different. Theirs also the Weapon R which works great. Their used on many drive by wire cars even heavily boosted Audi's.

Toyota's can be tuned with a piggy back, stand alone or if you actually can manage to find someone who's cracked them.

[tmontague]

yes they are technically tunable, I guess I was more referring to the ease of doing it compared to a Subie access port) or even a Honda.

The SB makes it feel like the response time is faster but it is just increasing your pedal throw. It is not and does not actually speed up the electrical impulse or signal to the ECU. It simply allows the driver to depress the pedal much less to get the car to WOT.

I've read various other car forums to learn about the SB and for the most part they had positive results. However they almost all agree that it is a simple device that does what you can achieve with your own foot but makes it feel much faster because you don't actually have to push the throttle down much to get to that point.

I can't remember what forum it was but some techy guy took it apart and wrote about how it was just a voltage booster but had no way of actually effecting the electrical signal speed it self.

I think it's likely a fun mod, just not cheap for what it is that's all.
