What to confirm for this Mazda5 and Premacy

Confirm the exact MZR, MZR-CD or Skyactiv-G engine rather than relying on the Mazda5 or Premacy badge.
- 02
Provide the model year, market, transmission and original ECU file.
- 03
Do not transfer parts or support assumptions between MZR and Skyactiv-G generations.
