Understanding the filename
The related catalog entry 89663-60E80 identifies the calibration family. The longer filename adds B_MOD_E2, distinguishing this file from that base identifier. MOD suggests a modified variant, but the filename does not establish what was changed. The meaning of B and E2 is not confirmed, so neither should be treated as a specific engine feature or emissions modification.
An engine control calibration determines how the controller applies its operating strategies under different conditions. The family association does not show whether this particular modified file changes fueling, ignition, diagnostics, or another behavior.
