IDENTIFY

Press 1 on HOME. This is the first question you ask about any file: what is it?

The IDENTIFY screen

Reading the screen, top to bottom

Line 1 — which file. The path you opened, its size (4,194,304 B) and a fingerprint of its contents (sha256 00f727e8abf6…). The path is relative to your home folder, so no long absolute path is printed.

Line 2 — the answer. Three green facts and a strength:

Bosch  ·  EDC17  ·  EDC17C66        detection STRONG        1154 ms

That is: the maker, the ECU family, and the exact variant — then how strong the match is, and how long it took (about one second for a 4 MB file).

The block under it — details the family stores:

Line In plain words
software the software version inside the file — the most important line here
calibration ver the calibration data version
SW base the base software string
serial a serial number written by the manufacturer
dataset the data set identifier
match key the name tag for this exact software
endian · cells · container how the numbers are stored, and what kind of file it is

Only the lines this family actually stores are shown. Others are left out completely rather than printed as blanks.

The bottom bar — what you can do next. [I] inspect [M] maps [C] cook [F] open another dump. The file you just identified is carried into whichever screen you pick, so you never choose it twice.

Why the match key matters

EDC17C66::1037541778126241V0 is the name tag for one software version — not for one car. Two files carrying the same tag are the same software, even if one is stock and one is tuned.

That line is what APPLY checks before it writes anything. If the tags differ, the tool refuses, because a change recorded for one version may not belong in another.

Keys

Key What it does
F open a different file
I go to INSPECT with this file
M go to MAPS with this file
C go to COOK with this file as the stock file
Esc back to HOME

If it says UNKNOWN

Some files are not recognised — an unusual ECU, an encrypted calibration, a file that is not from an engine computer at all. The screen says UNKNOWN and does not guess a family to look confident.

You can still work with such a file: layout, tables and checksums all work. And CONTRIBUTE is the path to adding support for that ECU.

Nothing is written to disk here. This screen only reads.
