Hey, i have an 89 ef hatch, and i want to convert from dpfi to mpfi, and im gonna buy everything for the swap on craigslist, but this guy has an ecu that isnt the PM6 ecu, but he said it would still work for the swap, but i havent found anything that says that? help would be appreciated
thanks

 

What ecu are you getting from the guy?

 

if you are switching to a mpfi setup...you need to run any 89-91 civic/crx SI ecu (PM6)

I know of a couple available but just noticed you are in seattle..im up in vancouver...

 

ive done the swap like 4 times..so im pretty sure lol

 

maybe its a pr4

 

^^^
That works too!

 

maybe its a pg7, its for dual cam but ppl still run em, i have one im not running, i use the pm6

 

pm6

 

I dont know, i asked him what ecu it is, but he never responded, and im still waiting for a response. lol

 

Even a ps9 will work if it's chipped. It doesn't HAVE to be a pm6

 

Ya, what everyone else said. You've got a couple options that will work

 

hey i have a 91 crx dx that i did a mpfi swap on and ive went over the wiring probaly 20 times and everything is wired corctly and the car will only rev to 3000 rpms no more and i tryed my ecu in a buddys car and it worked fine and i try his ecu in my car and it still just went to 3000 so if anyone can help it wuld be great

 

There are several ecu's that will work but the pm6 would work best, I would stick with that. civic88sedan, have you tried a known working dizzy?

 

no i have not but i am running a pm6 and i got the dizzy out of a running car before my buddy sold his hatch i took his mpfi swap out

 

Anyone have any clue to why its only running 3K Rpm? thoughts or suggestions would be excellent..

 

rev limits at 3k??

 

yea my buddy and i did a dpfi to mpfi swap and wen we were all done the car only revs to 3k and no more andi tryed the ecu in a buddys car and it work perfect and we cheack are wiring like 20 times

 

somethins wrong somewhere...its in limpmode, check the dizzy wires, theres two identical wires..there both white...could be switched around..

 

i just tryed that this morning and still the same thing my thought was the cps might be bad but idk

 

had the same problem check your tps did you switch the outer two wires around

 

anyone in oklahoma want to help me with this dpfi to mpfi swap?
