So I finally got around to installing the Sprint Booster that I've had for a while. It was a piece of cake to install. The only thing was I broke the small tap that secures the pedal assembly to the bracket. Number 2 in the diagram.

http://www.realoem.com/bmw/diagrams/r/a/224.png

Before installing I vacuumed out the car. After that I took a flat head screwdriver and inserted it into the side of the pedal assembly were the white tab is. Turn the screwdriver so the pedal assembly is loose and it will slide out. The white tab on mine broke and the assembly did not want to slide of the bracket because there was dirt that had gotten into the slide piece.

Once you have the pedal assembly off the bracket you now can go unplug the wire from the back of the assembly. Next you take the Sprint Booster and match up the connectors. Plug them in. After that you need to plug the switch wire into the housing. Then reinstall the pedal assembly. It took me probably under ten minutes.

The Sprint Booster is a really nice piece. It eliminates the lag when you hit the accelerator. I've driven 6 BMWs and acouple of non BMWs (G35, RX-8, and GTO).

Wow, very straightforward! Does the switch simply enable/disable the booster? Where do you put the switch?

The switch does enable/disable the booster. There is two settings with the booster on. Green light is Sport and Red Light is extreme. I've been driving around in the Sport mode. The difference is noticeable. Extreme is crazy. So better not drive with it in extreme mode when it's wet out. I have not figured out where to locate the switch. I'm thinking mounting it in the ashtray.

Oh wow, didn't know it had different modes . . . don't M3s have an "M mode" button or something? You (or someone else w/the Sprint) should wire up the Sprint switch to that button!

M3s, e60 M5, and e63/e64 M6 all have the "M mode" button. If my car had the individual switches instead of the one switch the DSC and heated switches that would work awesome.

I inquired about one on craigs list and the guy said he was selling it because he was getting shark, I did not get it beause it was the sprint booster without the switch. After I told him that I would prefer to have one with the switch he understood and still said that if I do get one in the future that he thought it was great and definitely worth the money.

Just to ask a 'dumb' question why would you do this solution over a full software tune such as the AA Tune or Shark Tune discussed elsewhere? They address this issue and a number of others.

ryankokesh
04-08-2011, 06:23 AM
Because a full software tune doesn't do a whole lot for us 325 guys. At least that's my understanding.

I'll probably pick one of these up if I can find a good deal on a used one...

Ooh - was asking cause it's about the same money new.. and if you have done any engine mods the tunes I think would do more for you...I looked at this for the wife's Audi out of curiosity cause there are no real tuner options and they don't make one for here 05 3.0 A4.. but after reading what it does was not sure I would install it anyway

I understood the booster has no effect after the shark injection as the shark does the same thing.

sooo...bump!

i am interested in the booster. i love the improved low-end from the shark, but the pedal still seems to delay. clutch feel and shifting have improved since the modified CDV install, but the drive by wire lag seems to be present.

so i'm curious...if i'm already sharkedd, will the sprint booster have much benefit? i guess i'm looking for feedback from someone who went from stock to sharked to sharked+booster'd...that would be great!

Precisely what I want to know... I too am sharked but still have a noticeable throttle lag that I do not prefer.

I'll let you know. I too, need more. Mine is on the way, as they were having a sale. I know many people just say "well step on the gas harder, you're paying for nothing", but I want better throttle response without having to have a lead foot. So, I've got the AA tune and I'll let you know how the SB works with it when it comes in. (I had to return the first one right after I got it due to issues).

I found this video describing what it does (basically just like someone said..makes the computer think you're pressing down farther than you really are). Sounds ok and easy to do, but i'll wait and see if i see a very noticeable change when i shark mine. (added bonus..install instructions as well in video)

BTW, how long did it take for your car to adjust to the sprint booster? Was your engine running perfectly right away or was there a break-in time. The guy at SB said it could take up to 1/2 hour.

I'm having strange problems with my SB. The 1st time I tried it, the engine would surge and rev erratically. The SB folks said to try to flip the connection, but mine really only fit one way. So, they sent me a new one. This one does the same thing, but now stepping on the accelerator with the SB in, does nothing. It's as if it's not even connected. Now, with this SB, I can actually flip the connection over and try it the other way (just to be sure). Problem is, same result. When I disconnect the SB, everything is back to normal. So, I'm not sure what to do. I may have to give up on it. It's such a straightforward install, I can't guess what I'd be doing wrong. Wondering if it's either just my car or because I have an AA tune. Gonna email them again, but I think I'm screwed and will just have to get a refund.

So besides the thorttle response, is there any performance benefit in terms of 0-60; 1/4 mi; horse power? At full throttle does it go faster than without, or does it just make up for the response in between idle and full throttle.

I thought i'd put in my two cents here...

I've got a sprint booster and had it installed last year (happy birthday!), and I have to say that it completely changed the way the car drives. It is almost always in sport (green) mode, and the difference in acceleration compared to without it is very noticeable, and so much more fun. Extreme (red) mode is almost too touchy for my taste, but can be a lot of fun every once in a while.

If you're considering- do it. Its a big difference for a relatively small price.

are you sharked as well or no?

From everything I've read, it just reduces the lag time that's a side effect of drive by wire. So, it will "feel" faster, but technically it's not.

I am not. It technically doesn't make the car any faster, it only eliminates the hesitation of acceleration. The moment you touch the petal the car responds immediately.

Kudos
09-21-2011, 04:13 PM
I know that the fly by wire throttle control "learns" your patterns and i know that the car always "feels" faster when the response is quicker. is the sprint booster, effectively reset the control everytime you get in the car, or is this response even faster with the sprint booster?

webster
09-21-2011, 05:35 PM
i think i'm gonna go ahead and just pull the trigger on this. it's got a money back guarantee and ECS has free shipping, essentially amounting to a free trial. if it doesn't noticeably improve throttle response i can just send it back.

The throttle body spacer is from AFE for the M54B25. AFE is developing a spacer for the M54B30 in the coming months.

My car is basically slow anyways, even with mods I feel. AFE claims 10hp and 14lb-ft with the TBS. I do feel a little difference but not sure if it just all of the mods. AFE intake, DAS, TBS, SB, and BAS hipo coils. I feel the SB was the best performance part I've installed.

There is just one way of installing the SB. Maybe the unit you recieved is defective. Can you return it?

I would imagine that this is nothing more than a resistor to regulate voltage to the throttle. I don't know the specifics but lets say 1/2 throttle is 6v, 3/4 is 9v and WOT is the full 12v. This thing merely adjusts the voltage allowed through so 1/2 throttle is 9v now. Can't imagine this having any impact on the 'computer' relearning your driving style. You're just pressing the pedal less to do the same amount of effort you do normally.

installed the SB today and....holy sh**!! the throttle improvement is night and day. i can tell it will actually take some adjustment on my part for smooth and aggressive driving. but overall i'm extremely impressed. i can really haul some ass right out the gate in 1st now. and with the combination of the SB + modified CDV, shifting is super quick and slick. great mod.

installation was simple once i got the damn pedal harness off. i ran the cable under the center console trim all the way to the e-brake handle and then just left the last few inches of wire leading up to the switch loose under the seat next to the rails. still trying to figure out where i want to mount the switch.

John, Sorry that I missed your post asking me about the TBS install. It was pretty straight forward. Remove the air box, both upper and lower intake boots, and unscrew the tb from the intake manifold. And then reassemble it.

He did put a lot of time and effort into this. I wonder if it was before they put the graph up on there website:

Which clearly shows that all it does is increase pedal sensitivity by decreasing the amount of throw used.

That pretty much confirmed what I thought about the Sprint Booster. I haven't used one, but I don't like the thought that I'm at 100% throttle only 2/3rds of the way to the floor. I only want better response for rev-matches, nothing more. I sure as hell won't be pressing a button to enable it every time I want to downshift, that's for sure...

I think this would be how you would mount the button to make it quick/easy... Just need to find a way to do it with ours

You've sold SBs? You have in stock? PM me price if so.

EDIT: Just read the review... wasn't that positive, but said what we already know. It's really about "feel". BTW BP, you don't need to press a button to activate it. It has different settings, from off, to on, to max.

Need to add my voice to the SB review now that I've got mine and been able to drive it around (albeit only about 30 minutes). So far I absolutely LOVE IT! I've tried both red (max) and green (med) and dark (off) modes. I'm going to drive in red most of the time. This is the car I feel like I paid for (but didn't quite get). It's hard to believe that the car is not faster because it absolutely FEELS faster. The throttle response totally changes the feel of the car. The kickdown on the freeway happens sooner, which was one of my main gripes. It's very drivable on the street. I have STEP, so it may be different for those driving manuals, but I absolutely 100% highly recommend this, as for me, it's what's been missing with this car. And, go through sprintbooster.us, as their customer support has been flawless, with no questions asked. Gonna rank right up there as one of the best mods I've done (along with AA tune). Why? Because how a car drives is what makes the car, and now the car drives more like I want it, with a much more responsive feel.

EDIT: Adding this: it feels like a "sport" mode for the car (even though I know the STEP has a sport mode). It would be nice to have a "sport" button in the console (next to the tire pressure indicator) with this button behind it.

i ran the wire up underneath the console all the way to the shifter and then just let the last few inches hang loose down in between the seat and the console. not the slickest install but it's ok for now. i don't shuffle between modes a lot (green pretty much all the time) so it works just fine for me.

Thread revival...

Just installed my Sprint Booster V2 with the mode button. I can't believe the difference this thing makes! I bought the original version that had no mode button and really didn't like how sensitive it made the gas pedal. For stop and go traffic it was kind of annoying. This newer version with the mode button is awesome! Set on Green for city driving is perfect, the car actually seems faster. I also noticed the tranny seems to shift better. It's alot easier to get the car to down shift to pass. For those on the fence about getting one of these you will be really surprised how it wakes up your BMW!

The Sprint Booster just amplifies the signal from the gas pedal so the response is quicker. I did research this exact concern and only found 1 guy that claims it messed up his TPS (throttle position sensor). Out of all the Sprint Boosters installed that's not bad. I believe they offer a 2 year warranty also.

Man I am so conflicted, reading about the SB...
On some reviews and forums, it's the most bashed 'con' of any 'mod' done to Bimmers...On others people rave about it. And then on some, like here, people KNOW that it doesn't increase HP or makes the car 'faster' but know that it makes you PERCEIVE that it's quicker and just enjoy the new throttle response....

So I think i would also like to have a bit more 'direct' feeling gas pedal (I have an auto ZHP), especially around down...I am thinking I might like the green mode for a lot of city driving that I do....

The concerns I have:
Is it hard to install? I've heard out gas pedals may not be that easy to slide to the left and be lifted off like in some youtube videos...
is the MPG gonna sink like a rock?
is the car going to be useless/unresponsive above 5k RPMs as suggested by this very detailed (unflattering) review? (Not that I live on 5k RPMs a lot..and one can turn it off any time, no?):

So should I Duh eeet too ??? I need some encouragement from the fam here..

johnrando
10-20-2012, 06:20 AM
So, removing the gas pedal is easy. It's just pushing down a tab and sliding. Finding the exact right place/pressure for the tab is a little tricky, and I broke mine. It still works w/o it, but I bought the replacement piece for $7 from ecs. And, the good news is you don't break it sliding it back in so that's a 1 time thing.

The final piece is connecting the plugs in the right manner. You do have to it just as they say in a certain sequence (keeping the door open so the electronics settle down, etc), but it's not hard, just follow the steps.

As for mpg, mine didn't sink at all now that I think of it...interesting.

Finally, the PDF. All I can say about that is that guy can do all the measurements he wants on his Mercedes, I love my SB. Here's an example as simple as it gets: I dropped my car off at the shop for a few days and had the SB turned off before leaving it. Upon picking it up, when I got back in the car, I had forgotten the SB was off and I immediately wondered why my car felt more sluggish. I remembered the SB was off, turned it back on, and voila, the responsiveness was back. It makes a difference in FEEL, and to me, the FEEL of the car is a huge part of the driving experience. It IS expensive for what it does, but a simple mod that improves the feel of your car every single time you touch it is worth it to me. It may not be to others, and I totally get that. For me, it's a no brainer.

WOLFN8TR
10-20-2012, 05:34 PM
The installation was about 20 minutes, that's including trying to decide where to mount the switch. When I installed my first Sprint Booster ( no mode button version) I too broke the mounting plate. But like John said it will still mount without the tab. This time I didn't break it! I've driven my car for a few days with the Sprnt Booster installed.

These are the main things I've noticed. I have a Automatic.

1. Gas pedal is more responsive, green is perfect for city driving.
2. Gas mileage unchanged.
3. A lot easier to get the tranny to down shift to pass on the highway, It's perfect now set on green.
4. The car does seems faster.
5. The tranny seems to shift quicker, smoother. Weird but it does.

My wife drove the car the other day and she said "What did you do to the BMW, it feels faster"? That is with it on the green setting!
The Sprint Booster made the car perfectly balanced. It's the way it should of been from the factory.

I will be getting the SB used and I don't think there will be a user manual etc - hence those rather basic questions; only thing I could find on the SB website is the installation PDF (which I think shows a different pedal assembly from an e9x)...

When the ignition is turned ON the SB comes on and you can change it no matter if the tranny is in Park, Nuetral, Reverse or in Gear. To be honest you really don't even need any instructions, mine didnt come with any either. The biggest thing is just getting the gas pedal off to plug it in. Then figuring out where to mount the switch.

Gary's right (as opposed to Gary Wright, for you 70's rockers). I'll see if I can scan mine, but it's very straightforward. You can change the mode anytime except they recommend not being on the accelerator pedal when you do it. Just push the button for about a sec and let off fully.

Regarding Sprint Booster. I pretty much completed my Sprint Booster/Sport Button mod and tested it out today....I was quite impressed and have to say that if it weren't for Gary's keen observation on eBay, I wouldn't have had the opportunity to do this mod so early...:)

I couldn't believe the OEM functionality that the Sport Button provides and how "Stealth" it looks. No additional buttons to mount anywhere on the car....just seems so natural to have this now...:) I really like using Mode2 for daily/around the town driving but switch to Mode3 (Racing) when going onto the onramps while merging onto the highway....my car becomes alive compared to it's stock settings....just amazing. I chirped my snows in this setting today with DSC on....first time I have done that since owning this car.

For anyone who haven't done this mod, or just get the Sprint Booster...you should seriously consider doing so. The throttle response is something to be experienced...I can talk about this all day long but the impact won't be the same....right Jon (JupiterBMW) ??? ;)

Agreed... I have to be honest here, I'm not the best person to post a review, but I did technically drive Rando's car with the sprint booster/sport button mod. First thing, I had never driven a steptronic, nor had I ever driven his car at all. Also, it was the same night I met John and William, so I didn't exactly feel comfortable getting deep into the throttle of his car. And let's not forget how insanely beautiful his car is, I would've been crushed if something happened...

That all being said, I did still drive the car, and I did check out all 3 modes of the Sprint Booster. Let me just say this, when the funds are available, I will also for sure be doing this mod. The change between each mode is VERY noticeable, surprisingly so in fact.

I think the key to the Sprint Booster is that you can't install it and just leave it to Race mode all the time. That would sort of defeat the purpose. The mod doesn't actually ADD any horsepower, or make the car any faster, it just feels that way. So, running it in race mode all the time sort of defeats the gain that it gives you. If you daily drive the car with the SB off or on sport mode, then you can kick it up when you want to play around or enjoy it.

That's my 2 cents on it anyway. Definitely noticeable, definitely fun. Like I said, I'll be getting one at some point.

Everyone have their preferences when using Sprint Booster. As John stated above, he perfers to use his in Race Program almost all of the time whereas I prefer to use mine in Sport Program 3/4 of the time. The only time I prefer to go into Race Program is when merging into highway traffic which I have to do daily when going to/from work. With Sprint Booster I have more confidence that I can merge into the traffic scheme with the same precision that I have when driving my ///M. The "old" ZHP felt good but when compared to my "Sprint Boosted" ZHP, the old one feels so much slower. My "new" ZHP now feels great! :biggrin

I know that Sprint Booster does not increase the horsepower of the car... tune programming such as Shark Injector, changing out your exhaust, headers, and adding a CAI will add some horsepower to your car. The Sprint Booster (feel free to correct me on this) improves the throttle response of the car so that there is less delay when you press on the throttle. What I like is that with Sprint Booster, there are three settings to choose from stock / Sport Program (my preference) / Race Program (John's preference).

Until I purchased my Sprint Booster, I really had no idea as to how much it would change the way I now look at driving my ZHP... all I can say is that with Sprint Booster, my ZHP is so much more fun to drive! Right now, I'm seriously considering getting Sprint Booster for my ///M! That's how much I love this little device!!! :thumbsup

oh....something to think about....
For those who are not inclined to do the Sport Button mod as John and I did, I still recommend getting Sprint Booster for your car...you will notice the difference! Gary was kind enough to provide Sprint Booster eBay links in the classified section... that's how I got mine! Instead of paying $299 + shipping I got mine for $153 with shipping included....jayjay went this route as well and got his for $100! So you can find them at a more reasonable price....just keep an eye out in the classified section :thumbsup

Doing the sport button mod does require some soldering skills and for some, nerves of steel. :) The surface mount LEDs can easily be burned if you're not careful and not work as a result...I found this out with one of mine since it does not work (Sport mode LED)... William's guide was instrumental when I did mine and I now know how to do this mod....one thing I will do different is get brand new LEDs so that I won't have to "reuse" any when I go back and redo my sport button.

Just read the whole thread... Thanks Charlie... :P

So I'm reading most of you who LOVE this mod are in a STEP, is that correct? I've got a 6MT and am debating putting this on my wish list.

That being said, would you do this or Shark first?

Dave,

Not a problem! :biggrin Just keep in mind that Sprint Booster works in both flavors. As you know, I happen to have this in my 6MT and absolutely love it! :thumbsup Seeing how I get to drive both the ///M and ZHP, I would say that the ZHP + Shark Injector + Sprint Booster makes it just as much fun to drive as the ///M even though my ///M has about 80hp advantage. I had a friend of mine drive the ZHP and I put it into aggressive mode and his immediate comment was "holy s***!"

If I had to do it all over I would have gotten the Sprint Booster first before "sharking" my ZHP but having both is awesome :p

My opinion is that the shark (or other tunes) provide real power, the SB provides better throttle FEEL. So, maybe that will help you decide. For me, I'd go with real power first (even if it's slight).

Here is a graph I made representing what the Throttle plate does when you fully floor the BMW with DBW.

The DME has full control no matter what or how hard you press on the pedal or at what rpm before 3,500, throttle will never be fully open. Even when the pedal is fully depressed to 100% the throttle angle is not 100% but more like 90% above 3,500. You can see that the maximum allowed voltage is 4.5V which would indicate the throttle plate is at the maximum swing at that voltage.

Time and time again I can only get a max of 4.37V and occasionally 4.39V.

So if you want to feel what a throttle wired car feels like stay at 3,500 rpms at light throttle and floor it lol.

I am hopefully going to get a chance to wire in the pedal signal to Unichip to see the voltage swing and see how it matches up. Looking at that Mercedes write up I doubt that the BMW even matches that. The BMW system is much slower then the Mercedes and why we would feel more of an impact with sprint booster.

Everyone have their preferences when using Sprint Booster. As John stated above, he perfers to use his in Race Program almost all of the time whereas I prefer to use mine in Sport Program 3/4 of the time. The only time I prefer to go into Race Program is when merging into highway traffic, which I have to do daily when going to/from work. With Sprint Booster, I have more confidence that I can merge into the traffic scheme with the same precision that I have when driving my ///M. The "old" ZHP felt good but when compared to my "Sprint Boosted" ZHP, the old one feels so much slower. My "new" ZHP now feels great! :biggrin

I know that Sprint Booster does not increase the horsepower of the car... tune programming such as Shark Injector, changing out your exhaust, headers, and adding a CAI will add some horsepower to your car. The Sprint Booster (feel free to correct me on this) improves the throttle response of the car so that there is less delay when you press on the throttle. What I like is that with Sprint Booster, there are three settings to choose from stock / Sport Program (my preference) / Race Program (John's preference).

Until I purchased my Sprint Booster, I really had no idea as to how much it would change the way I now look at driving my ZHP... all I can say is that with Sprint Booster, my ZHP is so much more fun to drive! Right now, I'm seriously considering getting Sprint Booster for my ///M! That's how much I love this little device!!! :thumbsup

oh....something to think about....
For those who are not inclined to do the Sport Button mod as John and I did, I still recommend getting Sprint Booster for your car...you will notice the difference! Gary was kind enough to provide Sprint Booster eBay links in the classified section... that's how I got mine! Instead of paying $299 + shipping I got mine for $153 with shipping included....jayjay went this route as well and got his for $100! So you can find them at a more reasonable price....just keep an eye out in the classified section :thumbsup

Doing the sport button mod does require some soldering skills and for some, nerves of steel. :) The surface mount LEDs can easily be burned if you're not careful and not work as a result...I found this out with one of mine since it does not work (Sport mode LED)... William's guide was instrumental when I did mine and I now know how to do this mod....one thing I will do different is get brand new LEDs so that I won't have to "reuse" any when I go back and redo my sport button.

I quoted my previous post because as some of you already know....I purchased Dario's Sprint Booster he had on his ///M when he purchased it. Having Sprint Booster on my ZHP has been a real joy to use... so much so that I wanted to get one for my ///M. When I saw Dario's "for sale" thread it seemed obvious to me to purchse this item. :)

I've had this on my ///M for a few weeks now and have to say I really love the minute changes it brings to my ///M. The changes aren't as evident as they are in my ZHP but they are there. It's like I now have 6 settings to choose from instead of the three I have in my ZHP. For those who own and drive the E46 ///M I can tell you that having Sprint Booster only adds more to the "fun factor" of driving these awesome cars :thumbsup

My preference has become having my Sprint Booster set in Sport mode (Green LED lit) and Sport Button off. I like the throttle response in this mode and on the most part it makes the ///M that much more responsive than it is in pure stock mode. For the "go fast" feeling I really have come to love having my Sprint Booster in Aggressive Mode (Red LED lit) with Sport Button engaged. All I can say is man is my ///M fast in this mode! My Butt dyno tells me that I'm now driving a rocket compared to what I used to drive before Sprint Booster.

My conclusion is obvious in that I love having Sprint Booster, even though it does not add horsepower to my ///M or ZHP, the throttle response has improved so much more with it than when I had my cars w/o it. Both cars are so much more responsive now and this is what I had always wanted in my BMWs :thumbsup

It does change the way the car feels / responses
I normally have it on green and when I feel like it I sometimes have it on green plus S mode on the steptronic
I don't think I ever had it on red
Wife accidentally did it one day ( I have my SB button hanging loose ) and it scared her

I talked to Charlie a couple weeks ago about the SB, and read through this entire thread. Now it looks like this will be added to my mods list soon. Thanks Charlie :P lol

Any time Bryant! :thumbsup When you get Sprint Booster you'll be thinking why you didn't get this sooner, I know I did! ;)
