What this calibration identifies
The complete identifier 89663-52R31 distinguishes this entry from other engine-control calibrations. The catalog also lists the same identifier without the .bin extension. Neither name identifies a modified variant or describes a specific change to engine behavior.
The Yaris and 1NZ-FE labels provide useful application context, but the identifier alone does not establish compatibility with every Yaris 1.5. Vehicle and engine control module details remain important when identifying a particular calibration.
