installing a perfomance chip - Page 2 - United Bimmer Community

I'm sure there actually is a chip. It is probably soldered in, making changing it a problem. If Dinan offers a chip, I'll bet you have to go to an authorized dealer to have it installed.

true...i wonder now how the shark injector works. Specifically, I am sure BMW didnt make it so 3rd parties could easily reprogram their chip.

What you do is you "shark" the computer and reprogram it.

**nightdevils** · 02-20-2006, 03:58 PM

Okay, isn't shark just flashing the reprogrammable chip on the computer? its gotta be eeprom in there somewhere.

^^ basicly yea

my car is 1994 325i sedan the ecu is 261 200 413
one more thing i realized was that not only the chip removed the check engine light i had before but also when i put the stock chip back the check engine gave a code 1222 which is lamda control 1 which i think is oxygen sensor before that the code was 1444(no fault)
now i dont know if my oxygen sensor is weak or the chip is crap
the car does not idle roughly i dont really feel a loss of power with the stock chip

I'll say this again.

EWS chips are only in keys that are gold.

If your key is not GOLD, you DO NOT have EWS.

Have a nice day!

I have yet to see a gold key. Harry (Komodo)'s key was not gold, and that was for a 97 328i. His 95 M3 key is not gold either.

**komodo** · 02-20-2006, 09:06 PM

^^ Yep. I know for a fact I have EWS on my 328, and I'm pretty sure I do on the M3 also... but both my keys are silver.

And actually, my friend Zak owns a 1993 325i that shouldn't have it, and his key is silver also, but has a flat, squareish top, while my keys are rounded and thicker (almost bubbled out at the top). Zak's other car is a 2004 E46 325i (with EWS of course) and his key is... you guessed it... silver.

EDIT: oh wait nvm, its only under certain lightiing it looks gold. my bad.

Are you sure?

I had a deep discussion with a technician that owns a 95 M3.

I was driving an e39 530i at that point and time, and we compared keys.

He showed me his and I looked at the e39s....and the e39 was indeed gold...and his was not. He said, an indicator of EWS.

Anywho

**94bmw325i** · 02-21-2006, 09:55 PM

yeah i think the technician was wrong.

**BMWLotAttendant** · 02-21-2006, 10:26 PM

I dunno, he's pretty good.

He transfered from Georgia BMW dealership....if that means anything.

Could be the 5 and 7 series have gold keys? And not the 3 series?
