AKA VHP

 

So true!! As I've said before, I've seen people spend more $$$ on carbon fiber $#!+, and I'm not talking about bonnets and hatches. You'll always have your skeptics. Luckily for me, this thing cured my problem.

 

The e-gas pedal is a very simple device. It has a cam that rotates a coupled pair of potentiometers so that there is a swept voltage created as you depress the gas pedal. All the sprint booster does is remap that curve. Two pots are used for redundancy so it's save (with just one pot, if it were to go to Vsupply from an internal short, the ECU would think the car is always floored. With two it can do a check of one against another to see if the readings make sense. FWIW, the throttle body has a pair of position sensors that work exactly the same way...)

While the electronics on this part are very easy to do and not that expensive, what you're paying for is the making of the molds to clone the factory connectors. I tried to get some factory connectors from the manufacturer (different one, but same supplier) and found out that the part numbers you see on the connectors in the car have BMW/MINI specific stuff on them and will only be sold to BMW/MINI. To get a "generic" version of the connector I wanted was a minimum 10,000 part order.

Now the connector used on the Mini one shows up in BMWs as well, but it's still a large investment to get the factory equivalent connectors to make it plug and play.

There will be no harm from the installation of the unit, but it will be personal preference as to if you like it or not.

ps, sometime factory settings are pretty conservative. Some Mustangs had a pause in the ECU to keep everyone from smoking tires. One of the largest drivers for ECU tunes for these models was to get rid of the factory hesitation. Another way to think of this is a "sport" button for cars that didn't come with one!

 

as usual a great explaination thx .

 

So I am thinking of getting one of these things My question is, since I am going to be installing a BV head, a cam and getting a tune, should I wait to see how my car is after all that? Or get one before the tune and mods so it can be on the car during the tune?

 

Uhg, I would kill for a schematic of this thing.

 

The Sprint Booster does not emulate a tune, and a tune can’t replicate the effect of a Sprint Booster. The SB will not corrupt the tuning process; it’s a non-issue there. If you have the money now, install the SB and enjoy. Pull the SB module before the tune and/or parts install to be reminded of what a dog the stock pedal is like, experience the enhancements improving VE and/or tune will provide, then re-introduce yourself to the driving pleasure the SB provides. Or you can save yourself a let down by never removing the SB again; driving with a stock pedal is so disappointing without one once you know better.

 

For those on the fence about trying it buy it from MINIMANIA and if it's as useless as the few folks here have stated return it and get you money back but be sure to let us know in your own thread that it didn't do chit. Then you can spend the money on a pair of these to make it easier to mash the pedal down faster.

 

So essentially the pedel isnt linear then? starts off slow and increases faster? Hmmmm I better go for a play and find out! im interested now!

 

If I Would Have Known the reaction the sprint booster had made. it would have been my first mod!

 

Jim, try to get the tune first before you decide to get this thing. We are always working on the codes and discovering new things to try... we tested the pedal-map adjustments in the ECU during our latest visit to Socal last weekend and the customer reported greater pedal response. These same adjustments will be available to future tunes...

Just for future reference, as we incorporate more features into our custom R53 tunes, the price of these tunes will be adjusted accordingly... the throttle-response is just one of the latest features.

PM or call me for more details :D
cheers.

Sweet Mike Hubie will be able to do all this correct? I hope to be doing my install in a couple weeks. I will give you a call this week. Jim

 

Is the sprint booster adjustable? Does it have a on/off switch?

Ever since going to the clutchmasters fx2oo and flywheel kit, I feel that there is extra lag time when I try to get the MINI going. But too much gas can cause wheelspin. But on uphills, the throttle response is slow enough to a point that I stall my MINI occasionally. I want to know if the sprint booster is adjustable, if it is, that should be a awesome product.

 

No, unfortunately it's not adjustable. It does take some getting use to as well. I don't know if you're experiencing what I did, but it could possibly help you out.

 

+1 and that is absolutely hilarious!!!

 

You hit the nail on the head. Thanks for a very descriptive insight into this product.

 

Ha!!!

I am waiting for mine.....

It does wonders on your car

 

that had a USB port so you could adjust the map yourself, and a switch to turn it on and off..... But I don't have the factory connectors, so one would have to splice the wiring to get it installed?

any interest? It would be cheaper for sure....

Matt

 

There are a few guys over on MlU cryin about the price, I said "why don't one of you develop one then" and got ripped BTW, do you know anyone that could do a "one push open" sunroof mod for the R56?

 

ha! They must be crying because a sprintbooster wont make thier car lower or look cooler

Anyway, I am getting one

 

let us know what you think One guy said Nitromini took his off? Last I talked to Lynn he said he liked it? With a complete refund, minus shipping, which might cost $8. why the heck not try it I am going to wait, as Mike said, after my install and tune to make that decision.

 

keep us posted! now i'm interested too

 

John Behe’s Custom Performance Tune/flash incorporates changes to TPS maps and what he calls “torque management” features, these areas were modified by John and not available as a DimSport map at the time. These changes were worth the costs associated with that tune/flash regardless of any peak delta achieved. I was very pleased with the improvements in throttle response following his flash. After experiencing the affect I wanted more of a good thing and is why I installed the Sprint Booster on top of it, not because the tune was deficient. Those of you who already have tunes, and think you have all that is available, should re-consider. I’m not saying Mynes’ new tunes can’t get you there, I don’t know because I haven’t experienced it, but for the others don’t dismiss SB’s capabilities just because you’ve had a tune or made real improvements in VE.

I don’t know why mdbsat is being coy, he briefly had one on his car on top of a tune and was suitably impressed, and that’s why he wants one full time.

 

ha! Am I being coy? Me? Maybe I just dont feel like getting into it with a bunch of people who have NOT even tried this product yet bash it every chance they can. It seems that EVERYtime someone talks about a product people have to come bash and talk crap about it. It gets exhausting. Dont like it? Don't buy it

I await mine with zen-like patience

post script- I tried one this weekend and it was AWESOME. Simply "flooring" it to try and replicate the effects of the SB will NOT do. I had to take off the SB, as it wasnt mine and let me tell you....its not fun having one then having to take it off again.

 

and it provides a *more* linear response, but still not perfectly linear. It seems like if you can adjust parameters to change the shape of the curve, you should be able to make it user-selectable. For the price, I'd hope you could choose from at least a set of response curves, rather than just the one they choose for you. Oh well. I know that the unit Dr Obnxs comes up with will have selectable response curves.
The reason I would want adjustable/selectable response curves is that my accelerator is pretty "twitchy" already. Not an "on-off" switch but no lag at all. I would want something in between I guess.

Let's all pressure Matt and he'll make it for us.
