Sprint Booster V.3 Ultimate Control. INSTALL AND REVIEW. E46 BMW

Johnston Research And Performance (JRP) has hooked me up with the new Sprint Booster v.3 to test. I was skeptical at first, but I discovered that I really like it. The super fast throttle response is very welcome in a drive-by-wire car. Downshifts are where it will make the most difference for me on the track. I also test the valet mode and pedal lock mode.

To clarify, this device amplifies the signal of the throttle pedal, allowing you to get to full throttle quicker.

i just roll my eyes when people say "just push the pedal harder". Dont you idiots understand that your throttle is NOT MECHANICAL in a DBW system!. You could push that thing through the floor and it wont make any difference. That philosophy is like saying that if you want a bold letter when typing, just hit the key harder.

@ 4:09 i was intrigued, @ 4:30 you piqued my interest, i was sold @ 4:36. All it took was 27 seconds and now I'm screaming "TAKE MY MONEY

The security of the "lock pedal" mode alone is worth the cost of this item! Thank you, very informative review!

I had a sprint booster on my 2008 Mercedes C300. These cars are notorious for lag in the gas pedal. Sprint Booster worked GREAT!!! Well worth every It is a must have if u have a car that has lag like mine did. A MUST

I have one of these on my 2005 E46 M3 since 2008. I think it's a version one.

If I engage sport mode on top of the Sprint Booster, it makes car a monster. The throttle response is ridiculously fast.

It's overpriced. It should cost $150 not $300. But none the less, I'm very glad that I bought one. I love mine.

People who say SprintBooster is a gimmick clearly haven't tried it. I've had it in my MINI Cooper S the last couple years and can't imagine driving without it. When I turn it off the MINI feels like a goddamn Prius even in sport mode. Once under way, it actually makes your car quicker because engine response is so much faster. Boost hits NOW, not in a second... Real world example: you need to pass someone and the window is very short. With SB you can hit that opportunity no problem. Throttle hits quick, turbo spools instantly and you're gone. Without it, you better think twice about that pass.

First mod I did after going from an E36 M3 to an '06 330i = Drastic improvement! Made the intake feel cable operated - like my ol' e36. 👍

My experience was similar (on 2006 N52 E60). It's just a mapping but the effect of it is substantial. The default mapping on drive-by-wire BMWs is very conservative and very unlike a cable operated throttle actually works. It's meant to give you more precise control and especially to smoothen out the acceleration and lessen the fuel consumption. The sprintbooster changes the mapping and really makes the engine feel stronger, but especially makes driving more fun because smaller inputs produce bigger results. It's kinda similar to quick steering ratio - if you like a car that reacts to smaller inputs, that feels alive, you'll probably like it.

I even installed the E60 "sport button" mod on my car in hopes that the BMWs own throttle remapping will provide the same effect as the sprintbooster and that I will be able to sell the sprintbooster then, but it doesn't. It's actually similar in 0-30% range in that power comes earlier in the pedal travel, but it still saves the last 20% of engines power to the top 80-100% range of the pedal travel. Springbooster doesn't do that. You literally get all the power in the 0-50% travel, as soon as 10% if you're in the low revs, which is how I remember cable operated throttle to work.

I leave it in green mode and just disconnect the controller, so nothing looks modded in the interior and I'm for the foreseeable future not getting rid of mine. Don't let the rationalization that is "just a throttle remap" dissuade you from trying it. How a car reacts to its inputs is very important and changes the "feel" of the car very much.

Its because the Sprint booster increase an electrical charge that the car computer gas pedal let's out at the moment you step on the gas. It's allowing the car to reach full throttle sooner rather than the lag you would normally get

I'm a guy who drives a pedestrian 2004 Toyota Camry and I was wondering why the acceleration response on it was so sluggish. I used to drive a '92 Lexus LS400 and even that felt more responsive than my Camry. Been searching around for this and it seems like the Sprint Booster is the closest thing to having the throttle response I had on my '92 Lexus. I know your audience are mostly enthusiasts but I can see this being useful purely from an econobox utilitarian car sorta point of view too.

I've had it for 3 months now and all I can say is race 9!! My 2019 mustang gt manual pp2 feels awesome now!!

[rmrdbaron]

I love sprint boosters. I would put it in any sports car i drive. Definitely a good buy. Great response!

[Marcosmercado]

I got it and I am very happy with it. I drive a 2018 Mini Cooper S and The difference is clear. I always regretted no getting a JCW, not anymore.

[sprok]

Done a lot of bolt ons in my car and sprint booster has had the most noticeable change

[jameslester]

It works great on my Colorado but read the directions! It says do not change modes while using the accelerator pedal. This is the way drive by wire cars should come from the factory.

[SBRDEF]

I've got the sprint v2 in my 2015 chevy 1500 and it makes a big difference in throttle performance. It gives you instant access to power as opposed to the momentary lag you get before power is delivered. It becomes a much smoother power delivery and makes the vehicle nicer to drive! Also from what I understand it will fully open your throttle 100% where as the stock throttle mapping at wide open throttle only opens 85%. I'll be buying version 3 for my mazdaspeed 6.

So glad Thomas kept with his channel and look at him now!

[ratcityrain]

I do not have a E46, but was looking to do this in my '17 Tacoma to make it more responsive and so far you have had the best video explanation on how it works with a good demo. Thanks.

[iSkateBoard]

it doesnt make the car top speed increase, but it does increase throttle response by a whole lot, so i believe 0-60 does increase because the is reacting way faster than usual, some of your pulls seems to come from a 330ci not an 325

[djsthemetereman]

I had this on my previous car & because the throttle opened much quicker it made my modded exhaust sound extra loud plus the response is unbelievable
