From what I understand, the shark injector simply plugs in the m3 and you press a button to reconfigure the engine computer. And this costs around 300!??? My question is, can this button be reused? In other words, can I get my hands on a used one so that i can be able to "press the button." Thanks.

Nope - When you press the 'button' your computer receives the upgrade and the injector receives the original programming. Basically swapping code .... If someone returned their car back to the original programming then perhaps you could buy an used Shark and it would work. Maybe someone else can comment on this theory. -
Once the Shark Injector is used, it is coded specifically for that one car's DME and cannot work with any other ECU.Comment

what does it do? sounds interestingComment

it d/l a software program into the car. Its the same as putting a chip in an obdI car.

its basically the easy way to get ur OBDII programmed.. well.. easier than taking the DME out..Comment

I don't think that it is that bad of a deal. On my old Mustang I bought a Jet Chip. It was like $230 from Summit and was a chip that I stuck into my ECU. Frankly I would rather pay the extra money for the shark because it doesn't require you to mail away your ECU and plugs without having to disassemble your car.Comment

From what my mechanic says, the Shark is better than a chip because over time, the engine tunes itself back to the original program so the chip becomes useless.
With a Shark, you can re-Shark the car whenever you want.Comment

Your car goes back to normal after some time and you have to reshark it?? Is this really true? If so how will i know when i need to reshark it?? Will i know only by seeing if my rev limiter doesn't reach 7000rpm anymore? :???:Comment

No that's crap.
The ECU is adaptive and will always slightly readjust the fuel and timing based on how YOU drive it. Conforti has debunked that "back to normal" myth for longer than he probably cares to think about it. The Shark reprograms a more aggressive baseline and of course the increased rev limit AND removal of the top speed governor. The limiter will NOT change once you have Sharked it, but if you drive around in 5th gear at 40mph, then the programming will eventually give you the best performance it CAN under those conditions, but if you're always in a somewhat "race mode", then the ECU will make sure you always have that "Shark edge" like it was designed to do.
The reason why some people claim the ECU reverts back to stock, is that they drive their car like stock and eventually they'll get similar to stock performance because of the adaptive nature of the ECU. SO, when they re-Shark it, they feel that difference again between stock and Shark performance. But, if they always drive aggressively with the Shark, re-Sharking will not yield any noticeable change, because the car is already performing better than stock because the Shark is doing what it's supposed to do!Comment

Cool. I guess i should be in race mode all the time.
Just kidding. that's not good for the engine or tires. It can become expensive, but i guess it won't hurt to play a little rough sometimes. :rockband:

This is exactly what I was talking about, I don't know about you guys, but I drive pretty mellow around town. With the Shark, you can just pop it in and reprogram every once and a while and keep the programming "fresh".
I regards to the rev limiter turning back on, that is as Max says, a complete fallicy.Comment

So this is what I gather from the posts. The shark can be used to put your car back to normal and then again shark it to enahnce the performance. So you could switch back and forth as you got to autocrosses and then drive it to work. Is this correct?Comment

You could but it's not worth it. The reprogramming is very subtle... it's not like a shot of Nitrous or anything. Just program it once and forget about it. You REally don't want to be continually programming your car's computer... it's touchy and you could fry it if you screw it up. When you want to make sure it's got it's max ooomph, then drive it hard on your WAY to the auto-x...

I know some people bring it back to normal for their emissions tests and then re-Shark.Comment
