Understanding the filename
The MOD label identifies this file as a modified variant. The A and E2 portions distinguish the filename further, but their specific meanings and any changes made to the calibration are not established by the available identifier. The related 89663-60L70 catalog entry does not itself describe a stock or modified feature.
The calibration identifier can help distinguish this record from other Toyota firmware files, but it does not establish compatibility with a particular vehicle or confirm what the modification changes in operation.
