Main flash and modified files
The catalog includes 76F0038AGD Main flash (736 KB) 89663-33702-.bin, identifying a 736 KB main-flash image associated with this calibration. The remaining entries are labeled as modified or tuned variants rather than described as the main flash.
SW#89663-33702- MOD_e2.bin carries a MOD_e2 label. The files 89663-33702-TUN_E2.bin, 89663-33702-TUN_E2_V2.bin, and 89663-33702_TUN_EVRO2.bin use E2 or EVRO2 labels commonly associated with an emissions-related modification. Such a modification can change how the engine controller evaluates or reports emissions-system conditions. The filenames alone do not establish the exact diagnostic functions changed or how each file behaves.
89663-33702-TUN_V2.bin is labeled as a tuned version, but its name does not specify an E2 or EVRO2 feature. Likewise, the V2 suffix distinguishes a named variant without explaining its calibration changes.
