There are a few issues with your file that need to be addressed before we can help properly.

File Analysis:

The file you uploaded (318d1037396567ORI.bin) is 1.50 MB (1,572,864 bytes), but the entire beginning of the file (at least the first 0x2000+ bytes) is filled with 0xFF. The estimated entropy is 0.00 bits/byte, which is extremely low — this strongly suggests the file is either:

• A partial read (only external flash / calibration area, with the rest padded as 0xFF)
• A corrupted or incomplete dump
• Read with a tool that didn't capture the full internal flash content

What I can extract from the strings:

• Bosch number: 1037396567
• SW/HW identifier: 0089SY0A3R5BKB131
• ECU type: EDC17C06 (note: the string says EDC17_C06, not EDC17CP02 — please double-check your ECU label)
• Variant: V3R5
• DTC init string: "(SWB init)" present — suggests some calibration data is in the file

Concerns:

1. EDC17C06 vs EDC17CP02 — the file header identifies as EDC17C06. The E91 LCI 318d N47D20C 105kW typically uses EDC17C06 or EDC17CP02 depending on production date. Can you confirm the exact part number from the ECU label (Bosch HW number)?
2. File size — a full EDC17C06 read via BDM/boot should be 2 MB (2,097,152 bytes) for the full flash, or sometimes 1.5 MB if only the external flash was read. With all 0xFF at the start, this looks like an external flash only read (e.g., via OBD with KTAG/KessV2 or similar).
3. 0.00 entropy — the preview is entirely 0xFF. The actual calibration data must be further into the file, but the tool metadata suggests it may be very sparse.

What I need from you to help with Stage 1 tune detection:

• What tool was used to read? (KTAG, KessV2, CMD, Autotuner, BDM100, etc.)
• Read mode? (OBD, Boot/Bench, BDM?)
• Full ECU label — HW number, SW number, Bosch part number from the physical sticker on the ECU
• What exactly do you want to detect? — Are you trying to check if this "ORI" file is actually original, or are you comparing it against a suspected tuned file?

If you're trying to verify whether this file is truly stock or has already been modified, I would need either:

• A second file to compare against (the suspected tuned version), or
• Confirmation of the exact SW version so I can compare known stock calibration values (IQ maps, rail pressure, torque limiters, etc.)

Please provide these details and I can help you further.

I need more context to help you. Your message isn't clear — "this is the one" what exactly?

Please clarify:

1. Is this the file you want to check if it's stock or already tuned?
2. Or is this the tuned file and you have another ORI to compare against?

Also, my previous questions still stand — I need this info to give you a proper analysis:

• What tool was used to read? (KTAG, KessV2, CMD, Autotuner, etc.)
• Read mode? (OBD, Boot/Bench, BDM?)
• Confirm ECU type — the file identifies as EDC17C06, not EDC17CP02 as you stated. Which one is on the ECU label?
• What exactly do you want to detect? — Are you trying to verify if this "ORI" is genuinely original, or are you looking for specific map changes?

Without a second file to compare or confirmed stock SW reference data, I can't tell you if this has been modified. If you have a second file (tuned or another backup), upload it and I can do a binary comparison.

this is the better file i think

I can see you uploaded edc.rar (76.55 KB), but unfortunately I cannot extract RAR archives — the server doesn't support it.

Please re-upload the file in one of these formats:

• .bin / .ori / .mоd (raw binary)
• .zip (if you need to compress it)

Also, 76.55 KB is extremely small for an EDC17C06 dump. A typical read should be:

• OBD read (maps only): ~256 KB – 512 KB
• External flash (P-flash): ~1.5 MB
• Full BDM/Boot read: ~2 MB

76 KB suggests either:

• Only a small calibration zone was exported
• The file is heavily compressed inside the RAR
• It's a partial export from tuning software (e.g., WinOLS project, not a full dump)

Please:

1. Re-upload as .zip or raw .bin
2. Confirm what tool was used to read
3. Confirm if this is supposed to be the ORI or the suspected tuned file
4. Tell me what you're trying to detect — is the goal to check if your car has already been tuned (Stage 1)?

Thanks for confirming the vehicle:

BMW E91 LCI 318d — N47D20C — 105kW / 141HP

That info is noted, but I still need the following to actually help you:

1. The file
Re-upload the file as .bin or .zip — I cannot open .rar files. The first file you uploaded (318d1037396567ORI.bin) was mostly 0xFF / empty data, so I need a proper dump.

2. Technical details

• ECU type — The first file identified as EDC17C06, not EDC17CP02. Can you confirm from the ECU label sticker?
• Bosch HW/SW number — from the ECU label (e.g., 0281018294, SW 8517706, etc.)
• Read tool — KTAG, KessV2, CMD, Autotuner, other?
• Read mode — OBD, Boot/Bench, or BDM?

3. What are you trying to do?

• Check if your current file is stock or already tuned?
• Compare two files (ORI vs suspected tune)?
• Something else?

Without a readable file and these details, I cannot perform any analysis. Please re-upload as .zip or raw .bin and provide the info above.
