Pin out of accelerator pedal to ECU
This is in the 2nd doc, but I made it a little easier to read.

well.. i have a masters in engineering from virginia tech, and by the looks of it... for parts, labor, supplies, and packaging... not to forget factoring in the pain in the *** in testing. its going to cost at least $250 + shipping to make this thing from scratch. OR.... you could just buy one!

IMO, the SB is absolutely worth the $. I just spent about 3 weeks waiting for a replacement because mine did start to malfunction. One day when i was backing out of my driveway i hit the throttle after backing up and...nothing, no go. One of the pins that plugs into the wire/cord that plugs into the accelerator broke off, no big deal i just sent it back for a replacement. I'm just lucky it didn't happen while i was on a freeway/major street. I think it might have been my own fault for not placing the sprintbooster part as careful as i could have when tucking it back up above the accelerator, as some of you may have experienced that it's quite a b*tch to get the accelerator pedal back in once you've taken it out.
The time i spent driving without the SB were not nearly as fun as when you have in plugged in. The throttle response is SO much better. It just feels like there is a beast underneath the gas. I do tend to drive faster with it on, and am getting like 1-1.5 miles less per gallon, but like I said, IMO it's worth the $.

Transistor- 2 cents
Resistor -2 cents
2 6 pin connectors- $ 1.00
Wire and plastic- $1.00
Having people send you $250 for the above-
Priceless

how about you build one custom and let us know how it goes... doesn't sound like it should be too hard by the way you describe it.... goooodluck

Right.
It's 2 transistors, per the schematic of the throttle mechanism.
No resistor required. he he...
Could just be an op amp.
Yoy have knowledge of whats contained inside the SB?
Pray tell, do share.
Funding? Send me an SB to measure some voltages.
Then we'd have to have it sent to some eastern european county to have it mfg'd, and imported illegally as to avoid any liability.

Yes, I have knowledge of what's inside. Open one up and take a look for yourself. It is not two transistors.
I'm not going to help reverse engineer the unit. I'm a EE myself, but there is no point in copying the unit to save $250. It will take more than two hours of my time, and I'm not going to pirate off an RE'ed project.

* its only 250 *
The schematic you're looking at is for the throttle, not the sprint booster.

Whats the cost of R&D if you burn up a ECU or throttle assy. in the process. Does that factor into the overall cost? Just a thought!

A little intelligent discussion?
It's amazing with the attitudes being expressed here, that anyone has done anything. Coilovers might cause damage to the suspension.
Engine mods might cause engine damage. More power is the root of all evil!
It's bad for the environment! Driving fast is a crime! (Drex? he he)
Tinted windows might cause accidents from not seeing as well out of the vehicle!!
We wouldn't have much to talk about if all people said, was wow, look at my
perfectly stock unmodded vehicle, wooo!
Whats the cost of an engine if the ASP pulley burns it up?
Didn't stop Buell from doing it. Did he reverse engineer it?
It had been done before. But at a rediculous price.
The next least expensive pulley made in the fashion of the ASP goes
for like 1500. I guess we all should have just ponied up our 2 grand and
not asked questions, or tried to come up with another solution.
The SB simply alters a voltage signal in an existing circuit.
Not rocket science. Hardly reverse engineering.
They didn't invent the circuit it goes into, or the concepts employed as to how the system works, any more than Buell invented the overdrive pulley.
So, you don't care to share if the circuit inside, has some chips, and if those
chips and components have pn's on them?
Man, people here just aint any fun these days. :
That makes me rather sad to see people's curiousity down to the point, where
no one gives a ****. Fine. I won't waste your time or mine anymore.

I do however disagree with you regarding the RE aspect. You are reverse engineering a developed product here. You're copying a circuit. That's like stating that copying an ipod's circuit board isn't copying because they are made of a bunch of standard chips.
Would you flash the chip a map that you developed yourself, or would you try to emulate the sprintboosters behavior?
Even if you figured out exactly what you needed (sprintbooster was smart enough to shave the part numbers and identifiers off every chip), you're still going to have to copy some aspects of the programming.
If it was as simple as a few passive components, that would be one thing, but it is more complicated than that. You are paying for the development of a product, not just the physical components.

Out Of Control!!
As for myself, it was only $250, it seems to work without killing my car, and I like it. Why would I be interested in reverse engineering something that I've already bought?
I hope that you are able to reverse engineer an acceptable product, and that it's as inexpensive as you hope. Personally, I wouldn't trust it, though, and it's worth the additional $247.98 to me. The Renntech pulley is now $995, btw.

Are you saying there is a microprocessor in there? I highly doubt it. The chip(s) you are looking at are most likely passive chips like AND or OR gates. He shaved the PN's because it is rediculously cheap to reproduce.

I never inferred people here are Neanderthals, even if it is so easy,
a caveman could do it...he he. Just kidding.
Just trying to have a little theoretical conversation, since I know there's some very intelligent people here. Now that there's a schematic and functional description of the circuit, which btw SB didn't invent. They just took and existing circuit, and changed the output curve of the voltages, which could likely be done with a couple of op amp chips and maybe a few other components. I'm not an EE, nor do I pretend to be.
I doubt what they've done is patentable, any more than the mp3 player is patentable as a concept.
And BTW, Apple didn't invent the portable mp3 player.
In fact they're made by many different manufacturers.
Diamond was actually the 1st I believe.
They didn't invent the memory, the hard drives, or the mp3 compression formats, though Apple has some formats of there own,m4a, etc.
But they did integrate the components in a pleasing a cool fashion, and got the Itunes store up, while Napster was still in court.
I doubt SB invented the chips, but if they have a software map of some sort, that would be copyrighted of course.
I don't think it could be done for 2 bucks, (but it might be) nor would I want to try, it's dangerous thing to modify the throttle circuit. But it could very well just be an amplification circuit. Likely not gates, since that would be digital, and looking at the circuit, it's purely analog.
For now it would just be fun to discuss it.
I'm interested in the concept, tempted to spend the money, but.....
looking at the circuit, I'd rather save my money for the PA beachfront property.
Picking up my new freshly painted rear bumper from the body shop tomorrow.
Only $650 total...dealer wanted 2 grand. Should I have just paid it?
Am I reverse engineering the function of the dealer by determining what parts were needed, purchasing, removing, and installing the bumper myself?
If a device that performs the same function COULD be produced inexpensively and safely, personally I think that'd be cool.

Has anyone had this problem where you turn the steering wheel to the extreme left or right like when you're in a parking lot and the steering wheel and gas pedal simultaniously click? like you turn all the way left, start turning back and the wheel and pedal click at the same time then turn all the way right and turn back and they click again? i must have not put the pedal back in properly.
the car is going in for service tomorrow because the shifter is getting really hard to shift so i'm gonna have them take a look at this clicking. i'll take my sprint booster out first of course.

So this happended to me too, so I re-installed it, pushing the extra wiring "up" if that makes sense, a lot better. But I can still hear an ever so slight clicking at full turn left or right? What did you guys do to resolve this. Where is it coming in contact with steering column, on the left right or above the pedal (so I know where to tuck the wiring into, thanks.)

I bought my Sprint Booster for $220, awesome device !
Cool gadget , gives a whole new driving experience.
Paid $220, cheapest I can find online. I can forward you the link should anyone be interested to get them.
Tempted to get the aggressive ones on my auto tranny
Anyone has any experience with the aggressive ones ?
