The CX-7 used the 2.3L MZR DISI Turbo throughout its run, with a naturally aspirated 2.5L MZR added in selected markets from 2010. Both require direct original-file and market verification. Their presence here is not a universal MazdaEdit support claim.

What to confirm for this CX-7
- 01
Separate the 2.3L DISI Turbo from the 2.5L naturally aspirated MZR.
- 02
Confirm the market and model year because the 2.5L was not offered everywhere.
- 03
Provide the original ECU file before assuming support from another MZR platform.
Priorities for the CX-7

Treat every CX-7 strategy as market- and ECU-specific until Justin confirms it.
