Supported Delphi ECU Families
The registry currently covers 2 families of Delphi engine-management ECUs. Originally produced by Delco Electronics (a division of General Motors), later marketed under the Delphi brand following the 1999 spin-off from GM. Common in Opel/Vauxhall vehicles from the late 1990s through mid-2000s.
The registry is designed to be extended — new manufacturers and families can be added without touching existing code. See CONTRIBUTING.md for details.

Confidence scoring
Every identification result includes a confidence tier so you know how much to trust the match. A High result means the file has strong, unambiguous identification signals; a Low or Suspicious result means you should double-check before relying on it.
| Tier | Meaning |
|---|---|
| High | File looks factory-fresh — strong identification signals present |
| Medium | Identified with reasonable certainty — some signals missing |
| Low | Partial identification — treat with caution |
| Suspicious | Signals conflict or appear tampered — inspect manually |
| Unknown | No extractor matched — file may not be a supported ECU binary |

Adding a new family
The registry is designed so new manufacturers and families can be added without touching existing code. See CONTRIBUTING.md for a step-by-step guide.
