I’m looking for a an ecu and was wondering if a 37820-P28-A52 will work in place of a 37820-P28-A51.

 

Yes, it will work.

 

Yes, a 37820-P28-A52 ECU can work in place of a 37820-P28-A51 ECU in compatible Honda vehicles, such as 1992–1995 Civic EX or 1993–1995 Del Sol Si models with a 1.6L SOHC VTEC engine (D16Z6) and automatic transmission. Both are OBD1 P28-series ECUs designed for the same engine and transmission setup, with only minor revisions between them—A51 for earlier models (1992–1993) and A52 for later ones (1994–1995). They share the same pinout, wiring harness, and core programming for VTEC operation, so no modifications like jumper changes or chipping are needed for a direct swap. Parts catalogs and ECU vendors explicitly list them as interchangeable for these applications, and users report successful replacements without drivability issues. If your vehicle has a manual transmission, opt for an A01 variant instead, as A51/A52 are auto-specific. Always confirm your exact model year and transmission to avoid mismatches.
