Look at a file

Nothing on this page writes anything. Every command here only reads.

identify

What it is: tells you the maker, the ECU family, the exact variant and the software version inside the file.

openremap identify original.bin

Read the Match Key line. Two files with the same match key are the same software — that is what decides whether a recipe may be applied to another car.

If the file is not recognised it says Unknown ECU — no extractor matched this binary. That is a real answer, not a failure.

analyze

What it is: everything about one file in one pass — identity, VIN, layout, maps, checksums and a health verdict.

(Trimmed.) Use this when you only want to run one command on a new file.

health

What it is: six checks and one verdict — is this file sane?

openremap health original.bin

  OpenRemap — Calibration Health
  original.bin  •  4,194,304 bytes  •  EDC17  •  HEALTHY

  identity      OK    Bosch EDC17
  checksums     SKIP  no known checksum scheme detected
  axis sanity   WARN  96 suspicious axis(es) across 344 table(s)
      0x288B3E X axis max 30000 (implausibly large)
  map count     OK    344 high-score table(s), envelope [188, 1044]
  erased blocks WARN  2 large erased region(s) embedded in data
  VINs          SKIP  no high-confidence VIN candidates

(Trimmed.) The important word is SKIP: it means "I have no way to check this", which is not the same as "fine".

checksum

What it is: which checksum schemes the file satisfies — and it never fixes them.

openremap checksum original.bin

  OpenRemap — Checksum Detection
  original.bin  •  4,194,304 bytes  •  0 known family scheme(s)  •  0 generic match(es)

A modern Bosch diesel gives exactly that: no known scheme, so nothing was checked. On a family the tool does know, it names the profile and the score:

openremap checksum GS20_90C0_64KB.bin

  GS20_90C0_64KB.bin  •  65,536 bytes  •  1 known family scheme(s)

  IronFelix family profiles

  Siemens GS20 TCU (64 KB data)      1/1 checks ok

layout

What it is: how the file is organised — where the program is, where the tables are, what is empty.

openremap layout original.bin

  original.bin  •  4,194,304 bytes  •  17 region(s)  •  74 ident block(s)

     Start       End       Size          Kind    Ent   Tbls   Conf

  0x220000  0x290000   458,752   calibration   5.58    267   0.95

(Trimmed to five of 17 regions.) Tbls tells you how many tuning tables sit in that region — the calibration regions are where tuning happens.

scan-vins

What it is: looks for vehicle ID numbers (VINs) inside the file.

openremap scan-vins original.bin

  original.bin  •  4,194,304 bytes  •  0 candidate(s) ≥ 0.4

  No VIN candidates found at this confidence level.

A candidate is only called a VIN when its own check digit passes; otherwise it is reported as a candidate with a confidence, never as a registration.

To be less strict, lower the threshold with --min-confidence 0.3.
