which ecu is best obd0
 

i got a pr4 running my 88 civic i am gonna use TE should i use the pr4 or find a pm6 to socket

Re:which ecu is best obd0
 

I beleive the Pr4 or the PM6 (90-91) have external roms and either one will work fine. I have a PR4 I'm going to chip here in a couple days.

Re:which ecu is best obd0
 

i got an xtra pr4 if ur interested. so u can jus chip the xtra then pop it in when it works

i got pr4s out the ass i just want to koow if TE responds better to the pm6

Re:which ecu is best obd0
 

no, it doesn't matter.

Well...some PR4s are tricky.

Since you have them coming out your ass use one with the code "PR4-A10" or "PR4-A02" and you should be fine when running the latest PGMFI code NG28 or NG48

I think the L10's do work too...but dont quote as Im not 100% sure. If it does, please come back and let us know.

Re:which ecu is best obd0
 

i'll let you guys know as soon as i get my pr4 back..

thanks

I got my ecu back tonight PR4-L10 and plugged it in and it WORKED!!!no cel code was throwing and no dash CEL on either..took her for a spin and wow no BOOST cut(NG48)but my wideband is reading 12.1-12.7 on boost compare with my PM6 which reads 11.0-11.9....car is '91 integra LS..
