Sprint Booster review for 370z 7 speed AT
 

Hey guys here it is... first let me just say im french so im english is not perfect so pleaaase dont flame me :tup:

i got the Sprint Booster installed today and wasn't expecting much to be honest. the install was a breeze, had to remove the pedal assembly but real easy stuff. take a small screwdriver and remove the little plastic cap so you can access the 2 10mm bolts at the bottom of the pedal and voila. Now I was surprised when i pushed on the pedal and got instant power my wheels started spinning even with the vdc on, normally it barely spins with the vdc on :driving:

The pedal response is definitely quicker. i can say it did cut the 1sec response when you smash the pedal in half if not more. I tried it in Auto and manual and tested every gear in manual mode. didn't really do nothing in 5-6-7 but 1-4 was very primed in low rpm's and im very happy with the results. btw it does not add hp or nothing its just throttle response but you do launch faster and rev quicker thats no bullsh*t.

Note that i tested this baby on race mode (red light shown in picture) and green light is like bmw's sport mode, and gray no light its deactivated. to turn the SB on you simply click on the led and your good to go. 1. off 2. green/sport 3. red/race

The pedal is more sensitive on race mode but after 5 min driving around i got it. i wouldn't recommend letting your GF or BF drive your Z on race mode because it does feel like the Z is really alive and wants to go crazy lol :happydance:

So after driving around burning rubber unintentionally i realized that wtf Nissan didn't give us a sport button for the real enthusiast drivers? anyway i got this gadget for the week end if i find its garbage he told me bring it back monday for a refund. but im keeping it... :tup:

paid 350$CAD installed. i know it might be expensive for some but you gotta pay to play :tiphat:

Results:
At low revs, the engine responds at approximately half the time in comparison to before.
The delay time whilst accelerating in 3rd and 4th gear and the engine in the mid-range, is almost zero.
Big differences in the higher rev range.
Improved response for downshifts and safer overtaking.

Good review!
Merci beaucoup pour l'effort et votre anglais et mieux que mon francais!!

really considering getting this. thanks!

Nice review, Thanks!

lol! Merci :tup:

So just for the record, can you confirm that this engine has plenty of bottom end? :)

it sure does and i cant wait to see the results combined with an uprev tune. i was in 3rd going up the hill and felt like i was in 2nd.

That's a great review, i'm happy there's another satisfied customer, pretty much everything you described holds true for the manual transmission too. First time i stepped on it, I wasn't expecting that much response either! Makes all the other mods seem that much better, fun factor way up! Have fun with it:driving:

Nice review!

If my tune does not help out much, I will be doing this right after. The fact that it is adjustable is like the icing on top of the cake, plus I am sure lighting up the tires puts a nice sh*t eating grin on your face haha.

Chinook is right about the fun factor! and it does compliment our mods.

haha your right but my 285's aint cheap so i gotta take it easy :tup:

Oh I'm definitely getting one of these.

update!!! today its 66 degrees (very cool) compare to yesterday it was 80 something with humidex. and i really felt the difference today and the only thing is i gotta be careful is my rear tires!!! ill need a new set soon if i dont relax! but its weird cuz its like im finally enjoying the full potential of my Z.

Not to be a downer. I just read the description of the product, all it does is recalibrate your pedal to make it more aggressive. You can do the same thing simply by hitting the gas pedal harder. A tune will actually change the tip in, resulting in more power and sharper response. Wouldn't money be better spent in that area?

My Prius has the same feature. It feels cool, but it doesn't do jack $hit.

That is true with the pedal, but response time is different. I honestly don't now how you can say that you wnt more resonse by going 3/4 pedal instead of 1/2 pedal day to day. Sprintbooster is legit, as i had it in me e55 and was cheap on ebay new. The e55 was an 05 though.

Its just expensive since the z is a new platform. Wait in a couple of years or search the FS ads and you may get lucky in a year or so.

you gotta try it to understand, tell me why then when i smashed the pedal i barely spin in stock mode and with that thing on race its goes side ways? and never in life youl have the feelin of a Z in your prius :p

Read the description of the product, all it does is simply change the throttle position. Let's assume you put your foot 50% down, instead of opening the throttle at 50%, they open it at 75%. How is that changing power? You can do the same thing by hitting the gas pedal harder.

in a way your right cossie1600 but your still going to have throtle lag if you open it 75-100% stock.

What happens in your 370Z when you hit the gas?

Usually, you get a full second of delay before you start moving. Sprint Booster eliminates this... you get a quicker acceleration from a stop.

The Sprint Booster is engineered to enhance the driving experience by providing increased acceleration time (eliminating delay) on drive-by-wire cars by continuously measuring and converting the digital signal and providing the ECM (Electronic Control Module) with a new and altered signal for much quicker response. The Sprint Booster improves response, increases pedal input sensitivity and delivers more impressive off the line performance you can really feel.

so what is the difference with blitz throttle controller?

Tip in/throttle plate openings are controlled by the ECU, not the pedal. The problem still lies within the ECU mapping, not the actual throttle itself. I am not saying the unit doesn't work (in changing how linear your throttle is), but you might want to look into ECU tuning instead.

so that's mean, functionality of the blitz and the sprint are almost similar...

is how much you press your pedal...

am i right?

ive read on the bmw/350z sites from people with tunes still having this problem so whats the deal?

I have an Uprev tune and still have the delay issue.

A tune cannot solve the inherent delay with DBW. While datalogging on my Evo, I found there was always a delay between the ECU sending the signal to open the throttle plate, or at least acknowledging that it had sent the signal, and the throttle position sensor actually registering the change. A device like this that actually adaptively ramps the throttle opening rate based upon your initial "punch" is a good way to compensate for this lag.

I know people are saying a tune can accomplish the same thing, but it simply cannot without re-writing ECU code or compromising driveability. I've messed around with DBW throttle tables on the Evo X extensively - you really don't gain anything over the stock settings. In fact, it consistently makes the car drive worse if you mess with the throttle tables too much, especially on a quick-spooling turbocharged car.

That said, I'd need to play around with a Sprint Booster on my Evo to make any fair judgment. It may really not do anything more than playing around with the throttle tables - it depends on whether it's actually "intelligent" or adaptive in any way.

by continuously measuring and converting the digital signal and providing the ECM (Electronic Control Module) with a new and altered signal for much quicker response so there's gotta be something more than just a diod or what ever it is that gives the signal to the ecu to have a better response and less lag?

Well for one it isn't even a digital signal, it is an analog signal at that point. There is no intelligence to this device, it does not connect to CAN or OBDII or anything except the pedal control unit itself. It is simply built to boost all pedal output voltages in the mid range depending on the "mode". The only lag it reduces is the speed of your right foot.

What I suppose it may do is some form of fuzzy logic on the throttle input signal. It may "learn" based upon what it supposes you're trying to accomplish - be it a quick 0-60 sprint, free-revving the engine, or easy highway cruising trying to save some gas.

Some basic calculus on the past x seconds of throttle input voltage could tell this little device quite a bit.

Who knows?

logically if it was that simple i think there would be a ton of companies trying to sell knock off's on ebay but thats not the case. the only competition out there is BLitz and its even more expensive. someone needs to buy one and tear it apart lol

From watching the videos and reading the descriptions I'm pretty certain that neither the SprintBooster or the Blitz have any intelligence. One video just shows a driver holding the throttle at a fixed position and then it progressively revs higher as he changes modes. This confirms that it is simply increasing voltage by a fixed percentage when the input is in a certain range.

I do have to congratulate Mini Mania on slick packaging and good marketing. Some people certainly like the feel of the more aggressively mapped pedal, and the fact that they are able to sell these at this price is impressive. I'm sure there will be a Taiwanese knockoff hitting the streets in a year or two for $99.

This one from Blitz has two auto-learning modes: Blitz - Throttle Controller Full Auto Pro - Nengun Performance

I'd be disappointed if it didn't do some kind of instantaneous analysis on the throttle input as well.

this porduct has been out for 2 years already so why the f..k i cant find knock off's? and it was awarded by Sema last year. kinda weird if its that simple i cant find cheap Korean models :icon14: anyway before anybody can say what ever they should buy one and check it out. and Chris i like the fact that your so certain without having the actual product in hand nor even tested this thing lol

edit: ohh and i dont miss that delay btw im pretty happy with the fast throttle response :D

I don't think anyone is saying it doesn't work (by changing how linear your throttle is), but you can pretty much do the same thing by hitting the gas pedal harder. ECU and its mapping are the problems, not the actual throttle or throttle position sensor....

In my Prius, i think they call it "PWR mode" even though it doesn't add any power.

Im with ya on this one....how can anyone knock it unless they have tried it.

x2. I was a critic at first, but it's not a bad investment. They're a lot "smarter" than just adjusting the throttle tables in the ECU, in that you can switch from mode to mode so you're not sacrificing driveability when you don't want to be.

Please read the quote above cossie. He DOES floor the pedal! You can't go any harder than that :shakes head:

My analysis is based purely off the information the manufacturer provides, video clips and knowledge of the vehicle electronics. Not saying it doesn't work to a point, if you like it that is all that matters.

I dont think smashing the gas will increase response time. the throttle position will still be in the same position that caused the delay in the 1st place, all you will be doing is sprinting quicker once the delay ends. This seems rather simple to me. By changing throttle position you get an increased response and the cars throttle moves quicker. Its correcting a mechanical issue, not a computer one. The ECU mapping can only do so much. Alot of these pedals are being designed for looks and i can see where some designs may go as far as to hinder throttle response.
i can see why maybe you would want to direct $300+ into another mod and i do see where mapping might play a role in what you are saying. but this makes alot of sense from a mechanical standpoint.

I know this product is controversial with most but I wanted to let you guys know that the guys at six speed online have a group buy going thats been extended thru this weekend (I think). I ordered one yesterday and the discount was $85!

Sprint Booster Group Buy - Page 8 - 6speedonline.com Forums

You order it directly from the vendor using the coupon code buried somewhere in the post.

I ordered yesterday morning and got an email confirming shipment this AM.

So do I just order from throttle boost.com?
