    If you're not going to be running a flap a regular HP will work just fine for the CSL conversion. You can use MSSFlasher (http://www.msstuning.com/mssflasher.html) to flash a modified version of the CSL software onto an unmodified HP. Instructions are on the website.

    If you want to convert the DME boot sector as well you're going to need to BDM it.

    Depends. Is your end goal to do a CSL conversion on the ECU?

    To have Kassel upgrade you non-HP to full CSL would cost $425 + shipping: https://www.kasselperformance.com/pr...re-conversion/

    HPs are usually $400-500+ on the secondhand market, but if you want a CSL conversion, you would need to flash the HP DME.

    So is there any advantage of picking up a donor MSS54HP ECU, or it will need to be recoded and will be more paint then convert my non HP to HP? For example https://www.kasselperformance.com/pr...s54-hp-tuning/ provide this serves. I can send them either my non-HP ECU or get HP one from donor, but that will be coded to a different VIN. What would be a better option? Sorry if this is a stupid question.

    Nope. Hardware differences are only related to year (HP vs non-HP). Firmware is different though.

    ^Just use MSS Flasher to reset the flash counter.

    Outstanding writeup. Is there a step by step on the AIF counter reset?

    TO-DO TASK LIST: (in order of priority)
    • disassemble more MSS54[HP] DME executable code? (ugh)

    ------ ORIGINAL POST ------
    Due to the severely fragmented nature of MSS54/MSS54HP information within this and other M3 communities, I'm starting a comprehensive information thread whereby I can maintain information pertinent to all things related to the DME of the E46 M3.

    This is a table of information auto-parsed from flash files taken from the ISTA CDs. If you have a version that isn't listed here, please PM me your .0DA file so I can add it to the list! (Please bear in mind that I'm not manually parsing and interpreting this information, this is extracted straight from the BMW AG files themselves.)

    This is a correlation table between software and hardware versions found inside the DME themselves.

    The variant is most easy to determine by size, 32kb = MSS54, 64kb = MSS54HP.
    The hardware number is the associated program space (.0PA) for which the data is correlated (.0DA)
    Version Information is taken from the .0DA binary itself, 0x7FB8 for the MSS54, and 0xBFB8 for the MSS54HP, and is 56 bytes long
    Program # is also taken from the .0DA binary itself, and is in two locations per file, one for the master processor and one for the slave processor. On the MSS54, these are located at 0x4002 for the master and 0x0002 for the slave. On the MSS54HP, these are located at 0x8002 for the master and 0x0002 for the slave.

    Checksums and unlocking:
    NickG explains why AIF writes brick a DME
    The ECU lockup due to too many flashes is not due to the EEPROM's characteristics. It's a 'feature' written into the boot code of the MSS52/54 ECU. This pseudo counter (which isn't really a counter) is different than the AIF counter present in other BMW ECUs. Actually, the AIF counter/limit is present in this ECU too. So you're still limited to 14 AIF writes (AIF counter), or about 60 writes in total (general reflashes). I've been able to come up with a way to reset the 'lockup' counter without desoldering the EEPROMs. It's helped tremendously with all the tuning required for a turbo kit.
    Unlock a bricked DME

    I desoldered both eproms using quality adjustable air heat gun, eproms are so close to the processors that it takes some skill to properly desolder eproms and not damage processor legs. Soldering it back together is a bit harder and requires some skill to use the flux properly and not make a mess.

    then I red both files using my wellem psop44 adapter for 29f400, dumped both 512kb files from eproms, then compared it to few other dumps that I have.

    As nick stated 60 flashes max. So I found this area at hex address of both 512kb files located at 4800 hex, in the empty field of FFs, there are 00s, other files had less 00s then mine. So I started calculations, my file has 120 bytes of 00, asuming they are 16bit, I devided them by two, this gives me a number of 60 the same number Nick G said. So I tuned them all back to FFs on both dumps. flashed them back into eproms, and my DME was unlocked, I made a test flash with cheap galletto and it works. Thanks to Nick G.


    CHECKSUM CALCULATION/VERIFICATION/CORRECTION - SOLVED
    MSS54HP
    CRC-16 Checksum algorithm determined here.
    Originally Posted by terraphantm
    Edit: Solved MSS54HP checksum algorithm, it's actually quite simple.
    It's easier to think of the MSS54HP file as two separate 32KB files. Method for calculating the checksum for either half is the same.
    Take the first 0x4000 bytes and move them to the end. So what was byte 0 is now byte 4000, etc...
    Now select the first 7FFC bytes. Calculate the CRC16 value for these bytes.
    That's your checksum.
    • In the MSS54HP, the segment order is important when calculating checksums.
    • The binary is divided into two main parts, and two subsequent parts per half.
    • The checksums are located at 0x3FFC and 0xBFFC and are 4 bytes long each.
    • To arrive at the checksum, reorder the data in the following format:
      • Segment 1: 0x4000 to 0x7FFF
      • Segment 2: 0x0000 to 0x3FFC
        Use a CRC-16 algorithm to calculate the checksum of those two concatenated parts.
      • Segment 3: 0xC000 to 0xFFFF
      • Segment 4: 0x8000 to 0xBFFC
        Use a CRC-16 algorithm to calculate the checksum of those two concatenated parts.
    • Append the respective checksums to the end of Segment 2 and Segment 4 with two bytes 'FF FF' (*needs more explanation).
    • Reorder the file as follows: Segment 2, Segment 1, CRC-16 Checksum (1+2), Segment 4, Segment 3, CRC-16 Checksum (3+4)
    • Save. Feel free to test the Perl script above, or have it test your checksum calculating abilities

There are three known locations in the MSS54HP variants, 0x28C9, 0x28CB, as well as 0x29CB that hakenTT-mss54 observed. Also, 0x1A7D is a location on the MSS54 as well as 0x29CB.

    • Raised rev limiter per gear and confirmed immediately thereafter
    Originally Posted by terraphantm

    Seems to be stored in a similar format as the speed limiter
    Code:
    Gears:
00 00 | 00 01 | 00 02 | 00 03 | 00 04 | 00 05 | 00 06 | 00 07
And in RPM:
1F 40 | 1F 40 | 1F 40 | 1F 40 | 1F 40 | 1F 40 | 1F 40 | 1F 40
8000 | 8000 | 8000 | 8000 | 8000 | 8000 | 8000 | 8000
