How to Identify your ECU
Hey guys, I wanted to get a thread going on how to indentify what ECU you have so that I can make a link in the FAQ thread. (and for the noobs who ask https://honda-tech.com/forums/images/smilies/emwink.gif )
So far this is all the info I got. If you have some more you can add, please do so. Thanks https://honda-tech.com/forums/images/smilies/emthup.gif ECU Part Numbers All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01 The part number consists of three components: Honda's part number for ECU, which is always 37820 Three characters (which are loosely related to the model of car/engine). e.g P72 Three characters (which are the revision of the ECU) e.g. A01 The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU. Here is a list of common ECUs: PG6: 88-89 Integra (all makes) PM5: 88-91 Civic/CRX DX PM6: 88-91 Civic/CRX SOHC Si PM7: 89-91 DOHC ZC (JDM 'EF' ECU) PM8: 88-91 CRX HF PR2: 89-91 ZC (Euro) PR3: 89-91 JDM B16A EF8/9 PR3-J00 or J51: 92 JDM Integra B16A EF8/9 PW0: 89-91 JDM B16A EF8/9 DA6-XSi PR4: 90-91 Integra LS/GS PS9: 88-91 4 door Civic EX Auto P05: 92-95 OBD-1 Civic CX P06: 92-95 OBD-1 Civic DX P07: 92-95 OBD-1 Civic VX P08: 92-95 OBD-1 Civic D15 JDM P0A: 94-95 OBD-1 Accord EX P13: 93-95 OBD-1 Prelude Vtec P14: 93-95 OBD-1 Prelude Si (non Vtec) P27: 92-95 OBD-1 EG JDM Civic 1600 sohc P28: 92-95 OBD-1 Civic Si/Ex P30: 92-95 OBD-1 DelSol DOHC Vtec Si/EG SiR P54-G31: 1997 Honda Accord 1.8 LS P61: 92-93 OBD-1 Integra GSR P72: 94-95 OBD-1 Integra GSR P72: 96-00 OBD-2 Integra GSR P73: 96-00 OBD-2 Integra Type-R (JDM & USDM) P74/75: 92-95 OBD-1 Integra LS/GS P75: 96-00 OBD-2 Integra LS/GS P2N: 96+ OBD-2 Civic HX Coupe P2P: 96+ OBD-2 Civic EX Coupe P2E: 96+ OBD-2 Civic DX Coupe P2M: 96+ OBD-2 NZ Civic SOHC VTEC P2T: 99+ OBD-?

Re: (JDMlifestyle)
great great, search friendly too https://honda-tech.com/forums/images/smilies/emthup.gif
edit: you should include links to pin-outs for common ecu's https://honda-tech.com/forums/images/smilies/emwink.gif |
Re: (jdmsiR20)
add to that my old PGMFI post. a quick pic in ID'ing a 5spd to auto ECU
http://www.we-todd-did-racing.com/we...MxeTU0MQ%3D%3D in 88-91 ecus (PM6, PR4, PW0, PR3, PM7): 5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00 Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80, L50, L51 92-5 ECUs (P28, P30, P61, P72, P91, P08) 5spd = 000, 001, 002, 003, A00, A01, A02, C00, C01, C02, J00, J01, J02, G00, G01 Auto = J50, J51, 901, 902, C50, C51, C52, A50, A51, A52, L50, L51, G51 96-00 ECUs (P2E, P2P, P2J, P72) 5spd = 000, 001, 002, 003, A00, A01, A03, C00, C01, C02, C03, J00, J01, J02, A11, C11 Auto = A70, A71, A72, A91, A92, C70, C71, C72, C91, C92 from the patterns we can learn the following: first letter = country of orgin J = Japan C= Canada A=USA G=Europe second digit, if 5, 7, 9 then ecu is auto usually third digit denotes the version/variation |

Re: (axhandler)
That's what I thought, but according to the parts guy at Honda, he says it's the obd model. I was like my cars obd-1 so why is there a 0?? SO he says you have an obd-0 ecu http://images.honda-tech.com/set1//smile/emcrook.gif WTF a obd-0 p28, ok!
