  • Can you identify this chip number?

    I'm hoping someone has their old chip from their E30 M3 and can help me identify which chip is for the stock US E30 M3.

    I have two E30's with aftermarket chips.

    The first M3 I replaced the chip with a turner chip and stored the stock chip in my garage.

    I recently bought a used M3 and it came with an aftermarket chip that's pinging.

    I rummage through my old parts bin and findout I've got two extra chips lying around.

    I want to install the stock US 2.3 chip but can't tell which of the two chips is the right one. Both chips look physically the same.

    Chip #1: has a white sticker on the top side 12 14 9 059 342

    Chip #2: has a silver sticker on the top side 1267355213

    I'd like to identify both chips if possible. I have no idea where the extra chip came from.

    I think the chip fairy put the second chip in the garage to mess me up!
    :grr:

    I did a seacrh on the internet for those part numbers.. the only thing I came up with is below:

    **************************************



    My original chip has a silver label with the number 1267355213 on the upper surface. The underside is labeled:

    8503 EV
    KOREA H

      Thanks jdaigle,

      I did a search on S14, but forgot to search the net.

      The description does sound like one of the chips I have, I just don't have the made in Korea on the bottom side. From that post on roadfly, it looks like the chip you found 1267355213 is a stock e28 528e series chip.

      Some info. I didn't realize about the stickers on the top of the chips...

      "If the center is not covered with a sticker
      don't let it see the light of day, it will
      erase the data."

      I'm guessing the other chip is for the stock s14 (12 14 9 059 342).
      Does anyone have their stock lying around and can read off the numbers on the label? A confirmation would be greatly appreciated.

        M3 chips are:
        1267355 547 (16k chip) or 1267353 785 (32k chip)
        1267355 484 (16k chip) or 1267353 787 (32k chip)
        1267355 631 (16k chip) or 1267353 788 (32k chip)
        1267356029 (32k chip)
        1267356186 (32k chip)

        the 12 14 9059342 is a BMW part number, have someone with ETK do a search to find out to what car it belongs. It's done like this:
        -start ETK
        -in the right column of buttons click on 'additional info' or similar
        -type the number and click on 'used in' or 'applicable' to see what models it's used in

            I can throw another part number in
            1267355 303 out of my 195bhp car


            Goodbye M3, you served me well.

              Thanks Hardtailer,

              I don't know anyone who has access to an ETK, but from your posts it looks like most M3's have the first 7 digits in common.

              1267355xxx

              I did a search on Maximillians on the other chip (12149059342) and just got this back...not much more info.

              Part Number Search Results : OEM Catalog
              Item Number
              12149059342

              EPROM

              So I'm still not sure which chip to put back in.

                Thanks for your response UweM3,

                Ok now I'm leaning towards putting in the 1267355213, since it looks like it may be a closer match.

                  FYI: none of the two chips were for the E30 M3. The number of prongs were not a correct match for the ECU.

                    THE ABOVE IS INCORRECT!
                    1267355 484 (16k chip) or 1267353 787 (32k chip) is NOT for an M3, but for the 320is with S14B20 the (black) sticker on the motronic reads 0 261 200 087.
                    I could confirm this after opening the (non-molested) ECU's of both my 320is'es.

                      to get things complete for future reference:
                      1267355213 is for a 325 ES 1986 0261200027

                      found through google on this site:
                      http://oridb.checksumm.com/index.php?dlid=475

                      also in further addition to my post above:
                      1267355484 (16k chip) has a pink sticker reading 0261200087 on the motronic. The 32k chip must be denoted by a black sticker reading the same ...087 number.
