If you're worried about throttle response just get your car tuned.

 

I had one for less than a year on my last car (2003 Maxima SE 6MT). One of the retaining clips broke on it, so I had to ditch the device. Imagine driving one day and suddenly have your throttle go dead. Kind of scary.

Cost-wise, I don't think it's worth the expense (new). Fortunately for me at the time, I only paid half the original price (used) in order to experiment.

The first time you plug this in is a hoot. What a change! You'll have an ear-2-ear grin for days to come. And while that's all fine and dandy, understand that it's all in your head. The car is not any *faster*. All it's doing is changing the signal curve from the pedal to the ECU so that you push the pedal down slightly less to get the same effect. This is *NOT* a performance mod, it's a brain mod.

After a few days or few weeks, it becomes the new normal, and you develop new muscle memory. And then the fun is over.

So... if you get one, get the model that let's you turn it on/off with an external switch. That way you can take charge of fooling yourself, and enjoy it when you want to, as a fun, entirely make-believe go-fast switch.

 

Why not just slam the skinny pedal to the floor and hold it down

 

I do have sprint booster installed on my 2010 G37x sedan.
I got it because i whanted to make the G37x as responsive as my G37 convertible.
G37x was sluggish and laggy on acceleration and gear shifts compared to G37 convertible.

After installing sprint booster, night and day difference...
The car is waaaay more responsive and no more shift lag.
It has 3 settings:
1. off
2. green--very nice for daily driving, almost in par with the G37 convertible response
3. red--insane fast response and acceleration, NOT recommended for daily street driving

After driving on mode 2 (green) for few weeks, i turn it off, just to make the difference, and it felt like the car was in limp mode without it...

My conclusions:
1. Yes, Is a bit expensive...
2. NO you CAN'T do the same thing by pressing the acceleration pedal faster or harder (i tried to replicate the effect many times, no success)
3. Once you use it for few days , you won't go back
4. Mode 3 Red - LOTS OF FUN - do NOT use it in traffic - can't be replicated, NO MATTER HOW you push the acceleration pedal.

I think the ECU see's the faster input from the pedal and react's faster.
The engine power is the same, but in normal mode you get that power gradually.
With sprint booster in green mode, you get the same power but faster.
In red mode you get all the power at once.

About tuning/ flashing... i don't have this options, since my cars are EU versions.
Even the ecu/tcm updates that are available for US models, are not available for EU versions.
I already added Stillen intake's but the only difference was the sound... even if there was some power added, it was too little to feel it.

 

I have a 2010 g37x looking for this sprint booster

 

From the "How it works" section of their website:

"• 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."

Also:
"
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.


Is Sprint Booster for everyone? Of course not, no performance product ever is. If you have a track car where you spend most of your time near redline, Sprint Booster is not for you - Sprint Booster benefits are felt in the low to mid pedal travel. Some people don't like the fact that Sprint Booster reaches full throttle before full pedal travel - if you routinely mash the throttle to the floor, Sprint Booster may not be for you."

Sprint booster is not for me.

 

Exactly right. Even the manufacturer tells you it's a placebo.


LOL, that's BS.

Enjoy your throttle signal mod, but don't pretend it's doing anything other than messing with your perception.

 

This sounds like another one of the those "Venom 400 Power Control Module"

Basically all they do is modify the signal coming from the TPS and tell the ECU you are giving more throttle than you actually are. If you are at 50% throttle, your ECU is seeing 65% or something like that. When you are at 100% throttle you aren't going any faster.

It doesn't add horsepower. All it does is wastes fuel.

 

I don't think there is any reason to hate on the device, the throttle in these cars is touchy at best and laggy as hell at worst. There are good write ups in the apexi controller which gives you a bit more range of input options.

I would like to believe anyone looking at this type of "mod" fully understands that it is only to make throttle response easier to manipulate and let you use less effort to achieve what you want. Whether that is getting smoother take offs (as the poster in the link above) or to get quicker downshifts in the auto from the ECU (no, you aren't actually shifting quicker obviously but telling the ECU you need more torque NOW in a much easier fasion then slamming the pedel down when you don't need that much acceleration)

The auto on overtakes on a highway or passing someone is such a pain in the *** to dial in on the throttle in these cars. I'm personally going to get one soon just to give my ankle a mental brake.

 

That's strangely defensive that you read "hate" into these comments, because the device is what it is... it's not a scam. Derision only applies when people misinterpret the device and scam themselves.

As a controller, the Apex-i device looks kind of cool, changing color and all. Clever visuals.

 

Sorry, wasn't trying to come on the defense, haha. I don't own the device as of yet, but many comments on these threads leads to "you are'nt faster..." "You don't shift quicker..." "It's all in your head..." Which while true, has literally nothing to do with how the device is made or marketed and almost never adds anything to the conversation other then the obvious.

Also, it's Sunday morning and I haven't had my coffee yet, so that's my excuse

 

^^^
That is certainly the typical response in car forums, no doubt. But the handful of comments here has been surprisingly tame.

Check out how the controller was integrated in this FRS. Can't deny it, that's pretty cool.

 

That looks really clean. I did notice the lack of blank buttons in the g37 which is a plus (no one likes those blank buttons, makes me feel like I'm missing out on something lol) but if there was just one on the left bank where the tunk release is, that would be a really nice spot in our cars.

Thought about cutting a spot between the two seat heater dials but not really wanting to rip out the entire center console to do it. I actually thought about it when you had the pics up of your short throw install haha.

Here's a pic where the buttons between the seat heaters would work. That's an IPL and I think that button is the snow button in this pic? I don't know though as I have RWD, so it may only work in RWD cars.

Why o why do they give us a button to turn off the backup sonar, lol.

 

Nice review! What sprint booster did you buy and where did you get it from?
