Comprehensive MSS54/MSS54HP DME Information

[heinzboehmer]

What is the 0DA supposed to be used for ? How do they relate to each other ?

An 0DA daten file and a partial bin contain the same data, they're just structured differently. Binaries are just easier to work with because of all the tools available that can interact with them (like Martyn's tool and the xdf definitions for tuner pro on GitHub). There's even tools available to convert between 0DA and bin files: https://www.ecuworx.co.uk/2016/03/09...tool-released/.

To be honest, I've never messed around with 0DA files because the binaries are easier to work with.

Im thinking maybe Rohacell.com
They have an automotive product

Is there any wiki or help that tells what each function of the XDF does?

Slowly translating the MSS54 funktion document. Otherwise there are hints such as what K_MD_ASC stand for

The readme.md of the first page at github gives some info such as:

K - constants, ie bit switches, flags, etc
KL - Kennlinnie - dataline, for example the linearization curves for sensors
KF - Kennfeld - Map table
The format usually sticks to type_datacontent_axis_axis so KF_TI_N_RF is map:injection:rpm:relative filling

Hello I am new on the forum I live in Corsica so please excuse the spelling which comes from google translation my car is a m3 e46 from 2002 where i have already installed the mss54hp with the csl nose and the carbon box i would like to know how to check that the binfull csl is correctly installed because the program numbers in the dme do not change after the flash thank you

Is there anyone that knows what is required to do the drive by wire delete,(software wise). So that you can use drive by cable on the S54?
Thanks in advance

This drive by cable never works for SMG as the DME needs to control the rpm.
For 6mt, I'm sure the DME needs to be bypassed the gas pedal encoded data input to avoid it generating the error flag when the TB position feedback not matching with the pedal input.

My understand is the MSS54 vs MSS54HP only difference is the flash PROM chips, 256KB vs 512KB. So to convert the MSS54 board to MSS54HP, one needs to remove the 2 chips (512KB) from a S54HP then read and save the files using something like the chip programmer below, then program the files into the two new chips (512K), i.e. AM29F400BB-60SC
from https://www.mouser.com/ProductDetail...W34bxMGA%3D%3D
then solder the new programmed chips back to the S54 DME board and now it become a S54HP DME.
Have anyone done this before?

There is no good reason to do drive by cable with this engine/ECU.

hello after installing a new non-virgin eeprom and reprogramming with vvid the restart dme not need some virgin eeprom by chance thank you

Odd question, I've been running the same software for quite some time(can't recall the version #) but I've had obd2 scanner and readers always working fine but somewhere along the line of my multiple revisions of my tune and refreshing, my OBD port no longer reports data to and scanners or gauges. It connects to the Bluetooth modules etc as there is power but won't connect to the car. I can tune and connect and read codes via INPA etc but regular scanners no. I know early 2000s there was that encrypted data stream recall. Mine is an 02 but indont know why it would stop working randomly when I haven't changed software versions in a long time. I'm still using a euro based software, same as I have been using for many years without issues. I feel it's almost like the same issue Awron had with their vent gauge where they say it doesn't work on some E46 M3's with a tune and Euro M3's.

Any ideas??

Do these maps look right? This is from a 0401 csl tune hosted this github modified for stock US m3 cams: https://github.com/YulCmr/MSS54_HP_C...info_gathering

I have an 04 M3 with manufacture date of 11/03, so I am guessing/hoping that it has an MSS54HP DME. Trying to understand what is different between having a standard boot loader (stock that came with the car) versus having a CSL boot loader.

Does anyone know the hex location for the ISN to clear out so I can realign a dme with the ews. It was in the old thread but I can’t find a cached version of it unfortunately.
