Notes

openremap families shows the same families that openremap identify recognises. If a binary is classified as unknown, its ECU family is not yet supported — see CONTRIBUTING.md to add support.
Fuzzy lookup: when --family matches no name or alias exactly, the five closest names are suggested with scores (rapidfuzz, MIT) — e.g. families --family edc16c → EDC16 — 91%, EDC1 / EDC2 — 90%, …. The exit code stays 1 (the request was not fulfilled); a totally unrelated query prints no suggestions.
For complete technical details on ident formats, file sizes, and binary layouts, see the manufacturer reference pages: Bosch · Siemens · Delphi · Marelli.
