ive got a ecu but cant figure out if its from a civic or a del sol and what code it is all it says is p3p

SkoundrelUSA

You sure its not P2P?

pat92si

ive heard of the p2p ecu but thats it, not that that helps at all. the search didnt bring anything up either.

morenoesrider

on the side of the ecu its got serial numbers and in between those numbers it says p3p i know that there is a p2p ecu but, i want to know something i have a 90 civic hatchback si, the engine was swapped for a b16a from a 94 honda del sol but im not sure if it has the ecu form the del sol or the old civic, so i want to find out how to determine that?

EGwhat!!!

i swapped a b20 vtec head on my b16. friend told me my vtec fluid was low, but i dunno where to check it. My vtech light used to work , but when i hit 6k nothin happens! i'm not sure but someone said that oem vtech oil is the best but when i went to the dealership they had no clue wht I was taling about...


HAAAHAHAHHHHHAHAHHAHAHHHHAHAHHHHAHAHAH, thats the funnest thing i had heard in a LONG time. hahahahah ****** great.


yeah thats the hole list.

Mr Hammond

Gimmie the part number off of it. It is probably 37820-P3P-XXX

morenoesrider

ya thats the part number, are u able to determine which ecu it is?

Mr Hammond

Ok, the last three digits of the part number are not XXX.

I figured you would see that and fill the "X's" in.

morenoesrider

thanks

morenoesrider

sorry ill go check that rite now.

SkoundrelUSA

maybe the Canada ECUs are different or something.

morenoesrider

the part number is: 37820-pr3- 003

morenoesrider

is the pr3 ecu the right ecu for 1994 honda del sol b16a engine?

Mr Hammond

Where did you get P3P from?

That ECU is a JDM B16A OBD0 ECU. Like from an EF SiR or DA XSi.

morenoesrider

sorry, my bad i read the code wrong the last time that i took the ecu out, i still have a problem though, my vehicle wont pass emissions, its running to rich, ive replaced everything to correct the problem, except for the ecu, ive had mechanics, other shops and even emissions tell me that it is probably the ecu, now, i need to know if the pr3 for 89-91 jdm b16a is what its making it run to rich? remember the eng is from a 94 honda del sol. if anyone knows you would be a great help.

Mr Hammond

Well you are running an OBD-0 ECU in and OBD-1 car. Which won't do **** for your 4-wire O2 sensor. Also, it will not flash a CEL which is why you have none. They were stored in the ECU. That's what the peep hole is for. So you really have no working O2 signal going to the ECU so of course the car is going to run rich as ****. You need to put the correct ECU in there.

morenoesrider

thank you so much for the information it is exactly what i needed to know, ill go get it as soon as i find it?
