Hello everyone,

I have a Mercedes W211 E220 CDI 150HP with Bosch EDC16C2 ECU, SW 1037376828 / CBOOT 1037369286, P321/C49.

I sent my car to a local tuner who chipped it. After getting it back, I compared the modified file with the original using WinOLS and found 3572 differences. The problem is that some of the modified areas cannot be identified as potential maps — not even with ECM Titanium driver 18349 (which is the correct driver for this ECU), and not even in WinOLS with the edc16_13.a2l DAMOS (EDC16C31) which I already tried. The changes appear as raw byte patches with no map structure recognized by any tool.

I want to understand exactly what was modified and verify the tune is safe. I have both the original and the modified file available.

I am looking for a DAMOS or A2L file specifically for EDC16C2 SW 1037376828 to properly identify all modified maps.

If anyone is willing to help identify the modified maps, I can upload both files.

Any help is appreciated. Thank you!
