Honda ECU part number 37820-P28-A02 (1992–1995 Civic EX and Si, OBD1, manual transmission).
No Hondata board. Has an empty chip socket (socketed for chipping) but no chip installed. Circuit board looks clean.
Case is rough: badly peeling black paint, surface rust on mounting tabs, SICKSPEED sticker on lid. Outer case label is worn and partly illegible; the part number is confirmed by the clean label on the internal board.
No harness or adapter included. Sold as pictured.
