Reading the calibration identifier
The filename Toyota.LC120.30D4D.76F0040GD Main flash (368 KB) 89663-60511-.bin.zip identifies the vehicle series and engine in its LC120.30D4D label. The related catalog number 89663-60511 is in Toyota’s engine-control calibration number family.

The 76F0040GD portion and the listed 368 KB main-flash size distinguish this file within the catalog.
