Supported Vehicles & ECUs

Last updated: 28 May 2026 — coverage list. Tested against real hardware where marked, simulator-validated otherwise.

If your vehicle isn't listed, OBD-II generic diagnostics (DTC read/clear, live PIDs, freeze frame, readiness, VIN) work on virtually every 2001+ petrol and 2004+ diesel sold in the EU.

Diagnostic coverage

Tuning coverage (ECU map editing + flash)

Engine and transmission control units we can read, decode, edit and write. "Verified" means we have tested against real hardware; "Seed" means the map definitions are wired but checksums or DAMOS offsets need workshop verification before production use.

What "Seed" vs "Verified" means

Verified — at least one workshop has confirmed the read/write/checksum chain works on a known firmware version, with a reference ORI binary in our regression corpus.
Seed — the map addresses, axis pointers and checksum descriptor are wired in code, but production-bound users should verify against their specific SW version with DAMOS or A2L data first.
Beta — feature behind a developer flag. Not recommended for paying customers without explicit consent.
