:yummie: :yummie: Hi All,

Need Some Advice,

I intend to install a sprint booster on my E90 320, any recommedation like where to fix or which brand or model better?

Will sprint booster cause warranty void from performance motor?

Tried my collegue 320i with sprint booster, very reponsive...

Thank You
:)
 
Re: Sprint Booster? Advice

Hi Marcusrichard,

Are you saying the sprint booster or the uni chip?? How much to installed, heard that it better the fuel consumption rite?

Thanks.
 
Re: Sprint Booster? Advice

depends
as for how much u need to ask BVO
different price for different car
and diferent package
as i retune the cpu, fix sprint booster and change k&n filter together
fuel consumption depends
as 5 series is much much heavier
its like a tank
cant imagine how a & series feels
 
Re: Sprint Booster? Advice

Ok Ok,

thanks for the advice, i will go and check it out...

hello bro...i oso thinking of sprint booster at 1st, then came pwr pedal..which technically is better in the sense that u can tune to the level of "sprintness" that you want, while SP is fix, so if yr gf or wife need to drive, they may not get use to it (like reverse parking), so some forumers sold their SP.
but finally, The Great white shark ask me to wait til Jun/09 as he will intro newer product soon.
or u may want to sms him at 96905511 (Wilman)
 
Re: Sprint Booster? Advice

Sprint Booster -> BVO

Power Pedal -> J4C
 
Re: Sprint Booster? Advice

How about a "Sprint Booster" with a control unit that can be

1. Dash mounted
2. Can choose between 4 settings to play with. 4 maps.
3. Can switch off totally so that your wifey won't get a scare for the new responsiveness.
4. Can switch between the 4 maps on the fly while driving.

Sounds cool???

I've personally tested the prototype beta model in a E92 335 a few days back.

It's totally fun man!!!

Stay tuned!

Sounds quite similar to the PIVOT 3 Drive ... is there something better?

Wat is the cost for dat?Tks...
 
Re: Sprint Booster? Advice

Just out of curiousity,

I saw so many good reviews on this. But since it just "trick" yr car into thinking that you are reving higher, wouldnt it be the same as you simply depressing the pedal more?

Or is this to overcome the throttle lag by modifying the ECU or something.

haha agreed.

Just use more energy to depress your accelerator more, will save u around 400 buck this this device.

It'll never be the same!

Try flooring your throttle, there's always a lag before anything happens.....

With the gadget, the response is immediate.

We don't floor our throttle during normal driving here in S'pore....

Wat we want is for the throttle to be more responsive so that there won't be the so called 'lag'......

Re: Sprint Booster? Advice

Hi All,

There will be different if you drive eith DTC off, it will be more responsive when you accelerate.
 
Re: Sprint Booster? Advice

The Sprint Booster is a throttle remap device. It steepens the gradient of pedal angle (x) vs torque response (y).




While it gives you better response, there are 2 sacrifices over stock:

1) Jerky acceleration - it becomes harder, and one needs to concentrate more, in order to accelerate the car. every degree of pedal you put gives more effect, so for smoothness you need to lessen the degree to half. Basically, HARDER to modulate. Doesn't matter if one drives like a kid/hooligan though.

2) Driveline shunt on deceleration - because the mapping changes, if you release the pedal, the throttle SUDDENLY cut off. Car drivelines were designed with default throttle mapping in mind, therefore, if you lift the pedal, the throttle still goes through relatively gradual throttle release, and driveline shunt doesn't happen. With a throttle remap, if you lift the pedal, the steep gradient causes much more sudden throttle release, causing the flywheel to lose driving force immediately and it will shunt the transmission, causing an audible jerk.

All these, if you have an auto car, the automatic transmission's torque converter buffers it a lot, but it still happens.

My car has a form of throttle remap which I don't use unless on track. Using it anywhere else gives me trouble and irritation. But it is manual car though. But I always think, if I want more throttle, I just step harder lah... on track got no time to step more, so hence throttle remap is good for me.

thks cenurion, its very insight-ful of yr post :yikess:
but i was still thinking like most ppl say;
"step on it harder n it will still propel u like u wanted...w/o the cost of SP"
i hv this small isue, that is, whenever i slowed down on a bend ,turning into main rd, I wanted to speed up quickly as to avoid potential on-coming traffice..hence I step on it.
But even though, there's this slack, which i felt, WHY? so will installing the SP (or PP or wat ever) help me?
:confused:
 
Re: Sprint Booster? Advice

I just want to share my understanding. Before installing sprint booster the gear change was happening at about 3000 rpm and after changing to sprint booster the gear change happening between 2000 to 2500rpm. So the sprint booster improves the fuel consumption.
 
Re: Sprint Booster? Advice

I used SP on my previous e90 320i..one word..SHIOK..probably can get a 2nd hand instead of brand new one..:)
