ECU problem

[murphymotorsport]

I got my car back from my mechanic and it's slower then shit he said he couldnt advance my timing and said i need a new ecu and now my car can go like 70 in 2nd and is slower then shit off the line......can someone help me cuz i dont know where to find a new ecu or what would work on my car my car is the 88 crx hf

[stang805]

look around on ebay or somthin, if you feel like doin the swap get the mpfi intake and a pm6 ecu

[91civicDXdude]

i think your car is "slower than shit" becuase its a 70hp HF.

[jeef]

Mang the Hf is all about gas milage... 62 hp, long ass gears, and congrats on getting the lightest year too.

i found this ecu on ebay will it work?

numbers on mine - 37820 pm8 L020 661 100107

numbers on ebay one - 37820-PM8-A030 660-123174

[Scott82]

if your car is a manual then get a ecu for a manual, if its auto, the get an auto ecu. Not sure how to tell the difference in the numbers

[murphymotorsport]

both ecu's are for manuels but i heard that all the numbers must be exactly matching?

[Scott82]

i havn't heard that but i guess it's possible but i doubt it

[1PhatCX]

yes, if they are both PM8 ecus then they will work
i'd suggest using an Si intake which is bigger and running an Si Ecu (PM6)

[murphymotorsport]

Would that work? my car is only an 8 valve and the SI is a 16 so i could change the intake manifold and the ecu?

[Ones&zeros]

i would'nt know but yes change the ecu, intake manifold, and distributor, for the mpfi swap. add a resistor from a si to that.

[1PhatCX]

his cars already got mpfi tho. so he shouldnt need the resistor box or dizzy.

[murphymotorsport]

so what all would i need to change to the SI ecu?

[Scott82]

humm, man i know you would have to have all the wiring probably since you have no ecu. cause if you don't have an ecu then you are going to have to run wires thru the firewall from the engine to the ecu. If your lucky and things happen to plug up then i am guessing that you would have to get a complete engine harness cause there are lots of sensors on the throttle body that you prob, dont have, dizzy, ecu of course, injector resistor box, intake, injectors, and thats if your lucky and you already have a harness running thru your firewall for some reason even though there is no ecu. So it would probably be a lot of wiring to pull that off but anything can be done

[murphymotorsport]

all the wiring is there and i have an ecu but a bad one (dosnet work)
