Not sure which engine you have?
The badge alone isn’t enough: in this generation, the same engine came with different horsepower ratings, each with its own calibration. Check the horsepower in your owner’s manual or vehicle documents and find the matching row.

Mazda 3 I tuning FAQ
Which tuner do I need for my 3 I?
Find your engine in the table above – each row shows the tuner and the price.
Is a tuning module the same as a Stage 1 tune?
Not quite. Stage 1 usually means an ECU flash tune without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
