Just ordered a sprintbooster...
 

I had a Racechip response control for my Audi and absolutely loved the drastic difference it made. I even took out the neuspeed power module because it just wasn't needed and the throttle booster was just that much better. Fast forward to now, others have posted great results on the 370 and I know it will be the best 300 bucks I could spend. There's something about the signal and the massive differences modding that signal will make with these drive by wire systems. Can't wait to get it and get it installed!

Nice! Been reading nothing but rave reviews from actual owners for several years now, I finally decided to pick one up myself. It's in the mail and should be here soon. I can't wait to lose this throttle lag! I will be getting a tune some time down the road, not sure when, but in the mean time this will help the car to be more responsive for everyday driving which I'm pretty excited for.

With all the tunes available I always have the itch but as with my first Audi tune I regretted having it and had countless coil pack issues so I swore I'd never do it again. New Audi I traded in on the Z I could not believe the difference the throttle mod made, and that really made me regret all the money, and I mean all the money put towards ecu flash, injectors, plugs, test pipe, coilpacks, and the list goes on plus I felt it greatly compromised the intigrity of the car. The sprintbooster thinking is brilliant, that signal can and will affect so many other aspects, like how the transmission shifts, all kinds of goodness. Can't wait either, it will be a great weekend for sure!

Let us know...
 

I am curious as to how this performs in your Z. Make sure you come back here and give your review as I am thinking it may be a worthwhile mod to my roadster.

I am also curious as to how easy it is to install - did you do it yourself or did you have some one install it?

Thanks and I look forward to hearing.

Im super curious too. That lag on a hot, humid summer day is sickening and embarrassing. Any particular brand out there ? or is it just Sprintbooster ?

Hello Brian, just dropping this off here in case you're interested... It's off topic btw.

The install is super easy but extremely delicate since so much ecu stuff is happening via that throttle connection. I know you need to hear the "clicks" when making the connections. It's so simple it's silly. It's just the "smart key" thing and keeping it out of the cars range will help in cutting off the electricity to the pedal. That's what throws a light on in the cluster. Unplug plug, plug sprint in and plug factory plug into booster, really easy. Just the key thing. I will do what I did with the audi and keep the key far away, keep doors open, trunk and hood up did the trick before, no issues whatsoever. Some don't get the factory plug clicked in all the way and throws a cel. Solid click connections are key. As I've learned....

I just installed mine yesterday, arrived in 24hrs from ordering. Made a huge difference, no throttle Lag. I'm tuned but never thought to ask for a throttle remap. It's so much better to have my car actually respond when I hit the gas. That Z lag is horrible.

Hopefully mine is waiting for me when I get home. I did find how to remove the pedal so install will be simple. I saw the plastic cover where the bolt is is pretty tight, any trick to getting access to the bolt. I even stuck a screw driver flat head for eye glasses and it was still tight.

Just jam a Flathead in the cover and pop it off, you may make a little divot. The floor matt covers it anyways

Looks like delivery is for Monday via UPS. Can't wait!!!

Mine too. Hope it makes a difference.

So from what I read
This increases the voltage so you have almost like a quick turn throttle on a motorcycle
I read you have dead pedal at the end as 100% of the voltage was applied at 70% of the pedal travel...hummm

Does this thing make that much of a difference?

I know that on our cars, even if you floor the throttle you will have a delay before the computer allows the throttle blades to open to 100%. From what I understand, this product eliminates or significantly reduces that delay. I will give a full review once I install mine next week.

Yes it will make a huge difference. There is so much more electronically controlled too, transmission shifting and speed of shifts. It's like anything else dsp controlled. I can't stress the difference it made on a turbo. I'd hear it spool so much quicker and made the audi a whole other car. Like you expect straight from the dealer in a high performance car. Now, I know the z will be just that much better. For me, it made me regret money spent on other mods. I can predict it will want more intake.

Brian in Bakersfield...

Just remember to switch it back to stock mode if you ever had to valet your car. Wouldn't want an unsuspecting valet guy to put your car thru a wall lol

Sounds good! Hope I see a big difference!

I see that these sprint booster's are an addition (of quicker throttle response) to an up-rev tune,etc...

OK fine so i ordered one ha ha

Anyone have a installation walk thru ?

Funny, peer pressure got to you!!!

Instagram @jandmaddiedad

Found this for pedal removal...
 

This is probably the most time consuming part...

Anybody got a video of Throttle response of the "Sprint-Booster" in a ~Z~ ?

Wonder if it will cause traction issues, I'm stock with the addition of K&N drop in's & have no problem out the hole...see video 0-75.https://vimeo.com/137730594 7sp.A/T

Yep, a careful application of the beans is necessary

Nice video, I love our Z's!

I'm hoping it will improve acceleration from rolling start/cruising. Standing starts are typically pretty good.

UPS just delivered my Sprint Booster. Now I just have to finish work and go home.

Dang!!! Now shipping shows Wednesday delivery

Take pics of install :driving:

On our cars, the "throttle blades" in the throttle bodies are 100% open all the time unless traction control needs to cut engine power, or vacuum needs to be generated for the brake booster. The pedal causes the computer to alter intake valve duration and lift via the VVEL stepper motors on each cylinder head.

This doo-hickey alters the voltage output curve of the throttle pedal. That's all it can do. It simply makes 10% pedal travel look electrically like 20% pedal travel to the ECU. Any delays built into the ECU's programming are still there.

Remember Toyota's sudden unintended acceleration debacle?
What happens if this doo-hickey goes into a fault condition and sends a 100% throttle signal to the ECU? It is plugged into all the right wires to be able to do so.

Okay, so just got back from a short trip to the gas station. Results:

The product works as advertised. It sharpens or quickens the throttle response. Is it possible to achieve the same results by simply pressing the gas pedal further down? Maybe. It appears to have greatly reduced throttle lag that was prevalent on low RPM, full throttle applications. Remember, I already have an Up-Rev tune where a lot of throttle lag was taken out, so I'm not sure if this is simply a result of more throttle being applied by the device, or lag time being reduced. Either way, it's fun. The car is snappy now and very responsive. Can you tell it's "fake" responsive? Yes. Will you care? No. Bottom line, if you're out of bolt-ons to throw at the car and want a mod that is simple and will make driving even more fun, get it. I don't think you will be disappointed, especially if you have not had your car tuned.

Well, I can tell a difference even with 100% throttle applied. Not sure how that's possible since I understand how it works and 100% throttle should still be 100% throttle. But from low RPM's I can feel a difference when applying full throttle. Can't really explain why, but I'm not complaining.

And if the doo hickey malfunctions and the engine goes full throttle, I'll just pop it in neutral.

Fwiw, a bunch of guys on the Audi forums would always try to down play what this does as well as the bimmer forums. Crazy thing on both those forums for years is that until they actually try it they hate it. As a previous owner of an audi with said device, it works well. There is a boat load of dsp happening thru that plug on that pedal. I guess for us that love this device, as well as the audi guys, as well as the bimmer guys, we've tried it and won't do without it. Referencing the various audi forums I was active in, the biggest haters of this device were always the ones never satisfied with the countless dollars they dumped into their cars and still was never happy. Anyone here in bakersfield want to try mine hit me up, it will sell itself.

Brian in Bakersfield...

You can get the same result from a tune by adjusting the throttle map, however, not everyone are readily to drop $600-800 on a tune without first having all their breather mods installed, which will add up to thousands. This simple gadget for 300 will eliminate the throttle lag on a stock car without running a risk of warranty issues from a tune. Anyone who doubts its ability can come ride in my car and feel it for yourself. I'm not trying to persuade anyone to buy this, frankly I don't care. I'm just here to share my experience with it when I get it installed.

Supposed ups delivery by the time I commute home today. Oh the emotional roller coaster...today, tomorrow...jk but still excited.

Got mine in yesterday. I should have it installed after work. I can't friggin wait! :excited:

Installed. It took about 15 minutes. Also I snapped a few pictures I'll post them later in this thread for anyone looking for a guide. I'm taking her for a drive now will give my feedback in a few.

Edit:
Okay so here's a quick guide of installing the Sprint Booster on my 370Z:
Step 1: Leave your door open a few minutes prior to working. I was told doing this will ensure you don't trigger a check engine light after you remove the throttle cable from the pedal. I did this and did not have any CEL :tup:

Step 1b: Remove the plastic cover at the base of the gas pedal exposing two 10mm bolts securing the pedal to the floorboard. I used a small flat head to pry the plastic cover out. Once the two bolts are removed, hold at the base and push the whole pedal assembly inward and slides up to lift the pedal assembly out.

Step 2: Carefully unlatch the throttle cable from the pedal.

Step 3: Throttle cable removed from pedal. Becareful not to pull on these wires.
http://www.the370z.com/members/zbrah...88748t-sb3.jpg
Step 4: Install the Sprint Booster unit on top of the pedal assembly. It only goes in one way. And make sure it is latched tight. Notice my switch is already connected to the Sprint Booster.

Step 5: Throttle cable is latched to the Sprint Booster unit. Again, make sure you have a tight connection here.

Step 6: I routed the switch behind the carpet and up through the steering column. Used a small piece of 3M double sided tape and placed the switch here for easy access, you can place it anywhere you want.

Also, I watched this video beforehand to get an idea of the install. There are some differences but the steps should be the same.



Brief review after a short drive:
I went straight to Red mode and I was very surprised how quickly the RPM jumped through the gears. It was an immediate throttle response. The car felt so much lighter and more responsive than it ever had. Coming out of a complete stop, I no longer feel like the car is bogged down and trying to get up to speed. Rowing through the gears also felt much smoother. Over all, this one simple gadget gave me an enjoyable feeling that no other mod I have done could match (intake, exhaust, tp). It really made the car comes alive! I am stoke for the drive to work tomorrow morning. I can't wait!

Update:

Red mode is too snappy and quickly got on my nerves. It was very difficult to drive smoothly. This could be due to my already having a tune that eliminated a lot of the lag, not sure. Changed it to green mode and this is MUCH better. Quick and responsive without being annoying. I will run the switch wire today and mount it somewhere so that I can switch back and forth.

Finally installed. Honestly it took longer to get the bolt cover plastic piece out, used a super small glasses screwdriver to pop out, and to get light to go out from door left open. Easy to plug in and get that click. For my auto tranny this works like a champ, stupid not to ever do or try it. Massive differences between the 3, off, green, red for the auto transmission. Changes everything. I hear my dry AFE drop ins sucking air in. Like with the dsg auto it wants more intake. Love it!!!!

Brian in Bakersfield...

Also, in auto mode you can adjust the shift speed by feeding the throttle in green mode, super cool. Paddle shifting is silly fun, fast, completely different and awesome!

My first post. hahaha. Bought a 2012 Sport Touring 7AT Roadster a few weeks ago. Traded in a 2005 Audi TT with an APR level 1 tune. Prior to the Audi I had a 2007 RX8 6 spd.

So yeah, I'm in love with this car. To me it's like a supercar. I was going to buy a Boxster but I've wanted a Z since 1992 so I went for it.
I'm not in love with the delayed throttle response and seemingly long pedal travel though neither is a big deal. I *thought* it was just me when I test drove it, but then I read the Jalopnik review and a few posts here and realized the car is "just like that".

I'm going to order the sprintbooster tonight. It sounds like that thing will fix it. I'm a little concerned it'll be too twitchy (for parking and such). Also, it seems like the car shifts much faster in both auto and manual mode when I'm at WOT. Like almost DSG fast (not quite though). Otherwise, it can be kinda slowish. Bhandy- does this thing really make all of the shifts quicker? I understand it's just upping the throttle voltage and nothing more, but if giving the car more gas, faster actually increases the shift speed I'll be so happy. Not to mention that 1 second delay when I step on it...
