Interpreting output files from bdm100.

**kombi645** · 27th November, 2021, 08:19 PM

Hey guys, having some difficulty interpreting files from a DME (bosch me9.2 bmw n62 engine) after a successful read with BDM100.
can someone take a look at these and explain what I need to do to get the .bin from them?
The read from the m58b chip seems to large at 2mb, I have similar .bin from 545i I found online, and the structure is different with smaller file size

If anyone can point me in right direction on this, much thanks and rep!!

I looked at your files. Everything's alright. No need to convert anything. An important file name is 650i-m58b. This is the bin format. File size is 2048 Kb (~ 2Mb). You can upload other files I will compare.

Thanks! It appears vastly different from the 545i n62. (attached)

Does the content of the .bin change when loaded into winOLS or TunerPro in any certain way? I have read somewhere that winOLS will decipher/unscramble the file, or something along those lines.. otherwise, it's un-editable.

The .bin from the 545i will align right up with the .xdf in tunerpro and the .bin from the 650i will not, even when looking at the 650i .bin in 2D or 3D mode, it doesn't look as clear cut as the .bin from the 545i

These are different ECUs. me9.2 bmw n62 ECU 0261209092 SW 377011 and 545i n62 ECU 0261209003 SW 368248

Even the file size is different (2Mb and 1Mb). So it’s normal to be different. Winols does not modify the files until you have edited it yourself. But the displayed content changes by changing from 8bit to 16bit, LiHo to HiLo, dec to FF and etc.
