OBD U.S. (88-91)
DPFi = Dual Point Fuel Injection
MPFi = Multi Point Fuel Injection

* PM5 civic/crx STD/DX; DPFi
* PM6 civic/crx Si; MPFi, 88-89 PM6's are not reprogrammable, only 90-91 are.
* PM8 crx HF; MPFi
* PR4 integra RS/LS/GS

OBD JDM (88-91)

* PM7 civic/crx Si DOHC ZC; semi-rare ecu
* PR3 civic/crx SiR & integra XSi/RSi DOHC VTEC (B16A)
* PW0 civic/crx SiR & integra XSi/RSi DOHC VTEC (B16A)

OBD-1 U.S. (92-95)

* PR4 integra RS/LS/LS-SE/GS (B18B); same programming as P74 & P75
* P0A accord EX (SOHC VTEC)
* P05 civic CX; uses 1-wire 02 sensor, convertable to VTEC (may vary)
