Engine ECU

Decoded model-year byte and OEM-matched Elantra N calibration family. The exact ROM repeats its ID at 0x200110 and 0x200160. Its model-year field at 0x201500 stores 0x46, which decodes to 2022 using the source XDF scale (X + 1952). Both factory dates are 2022-03-15. Hyundai documents the related CNN family on 2022 CN7 N DCT. Launch RPM values at 0x201A12 match the documented Elantra N reads and differ from the Kona N reference. Displacement and gearbox tables match 2.0T 8DCT. Exact market, donor VIN and Hyundai part number remain open.
