A catalog reference for Toyota and Lexus calibration 89663-30B11 and its MOD_E2 firmware variant.
89663-30B11-_MOD_E2.bin is a modified firmware file associated with the Toyota and Lexus calibration identifier 89663-30B11. The 89663 part-number family is associated with engine control software, so this entry tentatively belongs to an engine control module calibration.

Understanding the variant label
The related catalog entry 89663-30B11 identifies the base calibration. The filename 89663-30B11-_MOD_E2.bin adds a MOD_E2 label, indicating a modified variant. The label does not reliably identify the modification or establish what effect it has on engine operation.
