Identifier and variant
The related catalog entry is 89663-48A80. The longer filename retains that complete calibration identifier, adds the suffix -A and carries the variant label MOD_E2. The label identifies this file as a modified variant, but it does not establish what E2 means or which engine-control behavior was changed.
No corresponding stock filename or service bulletin is identified for this entry. The general role of the engine control calibration family should therefore not be taken as a list of changes introduced by this particular file.
