I got a question, maybe you guys can put some sense in my head.

Are all PR4 ECUs OBD1s and OBD2s? Is there any PR4 that are OBD0s

I need a OBD1 ECU from a LS but I'm a little confused on this matter. Thanks for any help.

i think pr4 was only available as an obd1 ecu

 

Pr4 ECU came off the 92 93 INtegra LS so yes its OBD1 and they also came on the 96-01 LS which are OBD2

 

Pr4 90-91 Ls/gs Obd0
Pr4 92-93 Ls/gs Obd1

 

Pr4 also came on the 96-01 integra LS which would be OBD2 according to this website

So basically I need a 92 or 93 LS ECU to run on my b18b1...is this correct

The engine is being built right now and I should get it back this weekend. I'm having the block bored and re sleeved for more boost, everything balanced, JE pistons, with Eagle rods. The head is a LS head with ITR valves, and Skunk 2 cams ( I don't know if those are good cams to have or not )ported and polished. I haven't decided what turbo I want to go with but I'll figure that out soon I hope. I just have never dealt with imports much, I have a couple of Tahoes so I familiar with domestics all day long, but imports I'm not that familiar with yet.

Thanks for all the info

you can get an ECU from 92-93 or 94-95 since there both OBD1. What car is this engine going in anyway?

 

So a 92-95 LS integra ECU is a OBD1 and will work for what I want right? Thanks again

It's going in a 93 civic hatch.
