Original-file review
Treat the Verisa as a distinct ECU application, not as a Mazda2 substitute.
Drivability and response for the exact 1.5L MZR strategy.
The Verisa used a 1.5L naturally aspirated MZR, but ECU coverage is not assumed from the engine family alone. Direct original-file verification is required.
Confirm the model year, 1.5L MZR engine and drivetrain.
Provide the VIN and original ECU file for strategy identification.
Keep parts and calibration requests specific to the Verisa application.
Treat the Verisa as a distinct ECU application, not as a Mazda2 substitute.
Prioritize smooth response and predictable part-throttle behavior.
