Is it possible with a distributor that plugs into a hf crx harness?

 

99% sure no dpfi won't work on mpfi

 

So what would be a good ecu that would work?

 

.........

 

So the pm5 will work fine?

 

Correct me if im wrong but a pm5 is crx hf?

If so it will run your b18b but ittll lag and will not rev passed like 5k rpm.

It wont work its a DPFI ecu

 

I am assuming you are staying OBD0.
Best ecu to use on your B18b1 is a OBD0 LS ecu. PR4.

 

^ agreed, assuming if you're gonna be going OBD 0.....if doing a OBD1 then P75

 

Btw this isnt all correct.

there are two version of the PR4
OBD1 PR4 (92-93 integra)
&
OBD0 PR4 (90-91 integra)

ONLY 94-95 Integra LS ecu are P74/P75

Just wanted to clarify. That is all.

 

i run the PR4, its a dream for the OBD0 LS considering that's how they came from factory, and no the PM5 won't run it considering it's missing wires for 2 injectors and stuff is in the wrong spot.

 

Good catch....I didn't even notice that

 

Looks like the pr4 ecu will be my best bet. Will it plug right up or will I have to do a few mods the the wire harness

 

you need to convert to mpfi https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/diy-dpfi-mpfi-swap-made-easy-2889205/

 

I found an pr4 obd0 ecu for an 89 crx. will this work if so i'll purchase it. I have an 88 crx si and i have a hf enfine harness.
