ECU Families:

"Pre-OBD" - Early fuel injection designs

"PGM-CARB?" - 88-95 in Europe OBD0-ish Civics with electronic carburettor

  • P01 : 92-95 Civic DX (EDM) (D13B2) with single electronic carburettor

Dual Point - 88-91 (88-95 in Europe) OBD0-ish DPFI Civics

  • PM5 : 88-91 Civic Std / CRX DX (??)
  • PM9 : 88-91 Civic Std / CRX DX (??)
  • P04 : 92-95 Euro EG DXi
  • PW1 : ??-95 Euro Concerto 1.5i

"OBD0 MPFI" (88-91 MPFI *Non*-Vtec Civics, Integras)

The following ECUs all share a common circuit board design(with some minor differences):
  • PG7 : 88-89 Integra (D16A1 - Electronic Advance)
  • PM6 : 88-91 Civic/CRX SOHC Si (1.6l SOHC)
  • PM7 : 89-91 Civic Si DOHC ZC (JDM EF3) (Euro A20A Also reported by Mark Lamond)
  • PP5 : 88-94 inc PP4. Honda Concerto, UK Rover 216, 220, 416, 420, GSi, Gti, ???
  • PR5 : 90-91 JDM Integra ZXi (1.6 sohc)
  • PS9 : 90-91 USDM Civic EX (1.6L SOHC - usually auto)
  • XE5 : 88-91 (dates questionable?) Mugen Race platform (ZC)

"OBD0 MPFI" (88-91 MPFI *Non*-Vtec Prelude/Accord B20A)

  • PK2 : 88-91 Prelude Generation 3 B20A Engine
  • PH3 : 86-89 Accord JDM B20A Engine

The PM8 and PR4 each have unique circuit boards, although their code is mostly compatible with the other ECUs in this family.
  • PM8 : 88-91 CRX HF (Euro ZC also reported)
  • PR4 : 90-91 USDM Integra LS/GS B18A1 (note: OBD1 PR4 exists too)

92-95 "OBD1" Civics and Integras

All 92-95 Civic and Integra ECUs use one of three board designs. Differences in ECUs are often as simple as a different program. Different portions of each "motherboard" can be populated to enable controlling vtec, automatic transmissions or purge solenoids.
