Modified and tuned file labels
Several entries carry an A suffix alongside the calibration number. 89663-0C530-A_MOD (2).bin is labeled as modified. SW#89663-0C530-A MOD_E2.bin and 89663-0C530-A_MOD_E2.bin are labeled both modified and E2, while 89663-0C530-A-TUN_E2.bin is labeled tuned and E2.
These labels distinguish the files, but they do not explain the modifications. In particular, the catalog does not define what E2 changes in these files or establish how any modified version differs in driving behavior from the main-flash image.
