hey i know this is a noob question but i couldnt find the answer i need in the archives. i want to know if this ecu is obd1 or obd0 because i see that it came out of 92-93 integras which were the years for obd1, but there was some arguements i read saying otherwise.

TIA

 

obd-1 for sure

 

nice, i was wondering the same thing, so does that mean i can use it for my ls swap into my ek that im converting to OBD1???

 

yes...u can also us obd-1 p75

The PR4 ECU was available in both pre-OBD and OBD-1 flavors, as confirmed by the part numbers straight from the Honda parts catalog:

- '90-91 pre-OBD Integra B18A1 5MT: 37820-<FONT COLOR="red">PR4</FONT>-A02, 37820-<FONT COLOR="red">PR4</FONT>-A10
- '92-93 OBD-1 Integra B18A1 5MT: 37820-<FONT COLOR="red">PR4</FONT>-A11
- '94-95 OBD-1 Integra B18B1 5MT: 37820-P75-A01
- '96-99 OBD-2a Integra B18B1 5MT: 37820-P75-A02, 37820-P75-335, 37820-P75-A04
- '00-01 OBD-2b Integra B18B1 5MT: 37820-P75-A05

 

I've got a 95 civic i'm swapping in a b18b1.. I have an obdII p75 ecu that came with it.. I wanna know if I should use an obdII harness from a teg and use that ecu, or should I use my stock obdI harness from my z6 with an obdI ecu and swap the sensors.. This is my first time doing a swap myself.. Questions keep getting multiple answers! lol.. Looking for the easiest route, which i've heard this is the simplest swap!

 

theres a few options
use stock harness(easiest)
easiest is finding a obd1 ls ecu. swap to obd1 injectors or to obd 2 injector clips,
swap to obd2 dist plug or find a obd1 dist

 

ya.. i think i'm gonna run the z6 harness and buy this obd1 p75

 

To address the original post, the PR4 does come in OBD0 and OBD1 varieties. A giveaway for the OBD0 version is the window for the CEL LED and the connector plugs on the ECU will be green/black whereas the OBD1 I believe is all grey.

 

Word, thats the answer I was looking for anyways ha. Thanks yo
