WTF? im lost

[92tegGP]

ok so my car (1992 Integra) its supposed to have a P74 ecu in it correct? Yes well I told this kid I would sell him mine because I dont need it anymore and I go out into my car and take it out and discover the sticker actually says its a PR4 (90-91 integra). So what the hell isnt my car supposed to be OBD1 and the 90-91 supposed to be OBD0? I'm lost. If someone could help me thatd be great...

90-91=OBD0
92-93=OBD1

Does your intake have the air boost valveson it? Doyou have a single or four wire O2 sensor?

IIRC, 92-93 had the PR4 then the 94-95 had the P75

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:
