New to the "Z" world.. Is a "Sprint Booster" worth it??
 

I just bought a 2012 370z 6 speed manual, has most common bolt ons like CAI, Test pipes, ARC Catback, etc.... Came across a thread here about a "Sprint Booster" and was wondering if this is a worthwhile upgrade or just save the 250$ and put it into a dyno tune at Z1 Motorsports (they are 5 mins from my house :tup: ) Thanks for any opinion you may have...

Save the money and put it towards a dyno tune

Get both.

This. All the sprint booster does is amplify the signal sent by the pedal. A tune let's you adjust the throttle tables themselves, in addition to a lot more benefits. You can get the same end result without the sprint booster.

Thank you for the fast replies... Ill just save money and put it toward a dyno tune

yep.

Why get both? What's the benefit of amplifying the signal from the pedal when you've already adjusted the curve in the throttle table to take out the lag?

is there any other place to order from if i decide to get this other then here https://www.sprintboostersales.com/

**edit** I went ahead and ordered it :icon14: Ill still have enough for a true dyno tune and what-not, but i hope i feel a difference from this little thing, i hope it gets rid of the sluggish 1st gear lag i feel upon acceleration... Time will tell. Thanks everyone

SprintBooster
 

I didn't care for it. It definitely increased response in the lower gears, cruising around town. But did not eliminate the lag when hitting "passing gear" on the highway. Like 60-65 mph. I sent it back. They do give you 30 days, and the service was good.
Just my 2 cents.

Edit, just read the Z is already modded......+1 on just getting a tune then.

:iagree:

Also, congrats on your Z and welcome. :tiphat:

I have both. When the SB is off, HUGE difference!

Did your tuner spend a lot of time on the throttle table? A lot of them just give it a once over and spend most of their time on afr and timing.

Specialty Z did it in about 3 hours

sprint booster is just a voltage multiplier. it's not a tune in any way. but considering the huge lag in the factory map, it does help close the gap.

just remember dat u will wot about 60-65% in on the pedal.

Im hoping it does something noticeable! so im little confused about what you said, will this help me gain WOT to close to 100%????

No, what it does is trick the car into thinking the pedal is pressed more than it is. The car thinks the pedal is pressed 30% more than it is. So at light throttle, it feels peppier since the car is responding like you pressed the throttle 30% more. The down side is that, since the throttle can only open 100%, you will be wide open at 70% pedal travel. There will be no difference between 3/4 throttle and WOT. So the last quarter of the pedal travel will feel like it's not giving it any more gas, since the throttle is already wide open.

Sprint Booster simply amplifies the voltage of the pedal position sensor. Essentially, this tricks the ECU into thinking the gas pedal is pushed down farther than it actually is. The end result of this is that SB has the ECU going 100% throttle (aka WOT) before you have pushed the gas pedal the full travel distance.

A real tune corrects the throttle lag from the factory tune and leaves your gas pedal with effective input over 100% of the travel. This allows more precise throttle input which can be extremely important when racing on the ragged edge of traction or drifting.

Having both just means there is a difference between how far you have to press the gas pedal to get the same resulting throttle input. This difference makes some people feel like the acceleration is better, but it's just a mind trick. The difference in how long it takes to push the gas pedal that extra distance without SB is negligible in the real world :twocents:

understandable..... well, it will be here tomorro so ill have something fun to play around with. once i get ready for a full dyno tune, i can sell it and recoupe some funds.

You'll definitely notice a difference. Just don't be fooled into thinking its doing more than simulating you pushing the pedal down farther. You should be able to recoup most of your funds selling it when you get a tune :tup:

push the pedal faster?

U shouldn't have to on a sports car.

Op- It's a dramatic difference with and without sprint booster. U might like it and decide it is enough.

most sporty cars these days come with different throttle curves u can choose on the fly. Basically it's like dat.

was looking for this thread then got moved... lol

I sort of disagree with that. faster you push for faster response/slower for slower responses.

op's choice but I personally would go with the tune after all your modding is done.

UPREV my throttle felt the same as before but ECUTEK, I noticed a world of a difference in response.

U don't know wat ure talking about.

Basically, just a light tap on the pedal, my car jumps like a MF! To me, that's what kind of result I was looking for. The nicest thing is SB has a few settings: 1. Green (Fuk me!) 2. Red (holly ****!) 3. Off

my tracking number shows it should have arrived today, but it didnt :icon14: . i wont be home again till tuesday (48hr shift) so i guess it will be here monday, so ill mess with it tuesday when i get home... ill post an update after i get to play with it. thanks again everyone :driving:

I have had a 2010 and a 2015. The problem does not exist on the 2015. The clutch issue is not a problem either.

:rofl2: yah, kinda like dat. lol'ed
