shark injuector

[socalguy]

i need to know if my 96 328is has been reprogrammed or not... b/c i want to
buy the shark injector but dont want to buy it if i already had it done.

So how do i tell if it has it or not?? will it be somewhere under the hood?

[CiscoKid]

if you see it under the hood then it has been done... if you dont, then it hasnt

go buy one if you want the extra performance

I could be wrong, but I think that if your ECU has been "sharked" you wouldn't "see" anything different under the hood...for example the one from bavauto plugs into that diagnostic port you hit a couple buttons and then take it out....I would try to contact the previous owner or run your car on a dyno...if it runs better than stock you know whats up.

[Autotechnica]

I doubt it has it, the shark only works for 1 specific DME number, it would be pointless for the previous owner to keep the Shark Injector.

Dyno probably wouldn't show any gains as shark injectors usually just raise the rev limiter. I would just rev the engine to redline and see where it's limited.

Or better yet...speed test that motherfu**er!!!!

should also provide some increase in HP and Torque. so a dyno may show something...

sharking is like chiping for the older versions its just it cant be chiped from the way ODB II is configured.

[Autotechnica]

Dyno won't work. Chassis dyno's are the only type of dynos you can do without taking the engine out of the car. Even if the Shark injector gave you a significant power increase (doubtful), that would only show up as a difference of less than approx. 5 RWHP at most. How would you be able to tell if this is your stock peak power or the shark injector? The motor has milage on it, which means it no longer has the same power output as when it was new. Also, BMW motors are mass produced and not blue printed, meaning HP ratings vary by a bit on each car.

Regardless of whether or not a dyno would tell you much, it's doubtful that it has been sharked. It's not like those are ten bucks at AutoZone. The previous owner would have told you about it if it had. If you got it from a lot you can't know for sure, but if it has a replacement exhaust, upgraded filter, etc. these may be tell tale signs that it might of been.

At any rate, if ya wanna be sure, go buy one. You can reverse the process once installed very easily and its probably worth it on a the OBDII cars.

[socalguy]

so i wouldnt be able to tell... so what would the car red line at if i had one,

and what would it redline at if i didnt have it sharked?? so i know. and can you

share these shark injectors then since all it does is reprogram it?

[BlantonG13]

Autotechnica said in another thread I left that he had a friend who had a shark injector and you couldn't tell any difference at all and that it probably wasn't worth it...Jllphan, how much does an ODB conversion run for say a 318i?

[mikester328]

With all that redlining stuff... wouldn't you blow the engine or something? That red line is there for a reason....

[BlantonG13]

If you keep it there for a prolonged amount of time you could easily blow an engine, but thats also the engine's "limiter" so it doesn't blow. The needle of the Tach bounces on the redline when you are gunning it...if it goes above redline, then you know there is a problem. If you have a Shark Injector, the needle would go past the stock redline point and begin bouncing at the new programmed redline.

Socal, I believe Sharks enable redline at 7700 rpm or something close to there.

[jllphan]

The OBDII-OBDI conversion would most likely not be a cost effective investment on the 318. IF it is a 96 or later buy the Shark, if earlier, buy a chip. Neither are gonna do a lot. The BMW 4banger is a fantastic engine but powerful it's not. Enjoy your gas mileage, and if you want to raise the fun factor, follow Autotechnica's lead= lighten and firm the chasis. This will make your car a lot more fun to drive then by adding a few measley hp....

The redline test isn't a great idea. Pre and post shark there is still a rev limiter which will prevent serious engine dammage, but it's still not a great idea to sit there and mash the pedal with no load on the engine for prolonged periods of time...

[BlantonG13]

thanks Jllphan...it is a great engine...the thing is a tank and the mileage is awesome. I was just inquisitive to the possibilities. Suspension mods would be a good idea...just a matter of time and money. Thanks dude!
