Embedded ECM number, year code and byte-matched DCT calibration. The original stores the calibration at 0x200110 and 391602G558 at 0x21F620, with stored year code R. Its 0x20000–0x1FFFFF program matches the 2024 Elantra N manual and DCT reads. Gearbox-speed setpoints at 0x205D08 and the automatic gearbox delay table at 0x21B4F8 match 2G557 DCT and differ from 2G553 manual. The gearbox comes from the calibration comparison.
