Current MazdaEdit coverage

Published coverage and verification

Skyactiv-G is the principal supported family. MZR, MZR-CD and Skyactiv-D entries are included for accurate vehicle identification, but support is never inferred without direct ECU verification.

Listed coverage

Open the Models directory for the reviewed vehicle and model-year matrix.

Not currently tunable

Open the Build Checker for the current unsupported applications.

2023–2025 Mazda3 / CX-30 naturally aspirated 2.0L without EGR

ECU prefixes PA, PG and PS can be tuned. Prefix PV is not currently supported for the 2.0L.

Coverage can change with model year, market and ECU strategy. Send your complete vehicle and ECU details to Justin before purchasing MazdaEdit or hardware. A model appearing in this list is not, by itself, a promise that its ECU definition is supported.
