sry for the terrible quality...i know it says pr4...but what determines like if its a manual and such...the reason i need to know this is becuz this is my ecu and its fried...and ive read up on these and some say its for a 92-93 teg, some for 90-91, and the ones i see on ebay... insteady of mine saying "AR" say either "ABL","AC","ABJ","AS","AT" thers probly more but whats all that crap mean?

 

looks like a PR something, at least thats what i can make out

 

... its a 4...not my fault my phone takes shitty pictures...thas not my question tho

 

haha my bad not only do i suck at reading blurry things but i suck at reading in general

 

Your other issue is confirming if its obd1 or obd0.

 

from what i can find it seems like it is from an integra ls swap and is for manuals but someone can correct me if im wrong

 

well i would hope so becuz ive been using this ecu for about 2 years in my ls swapped manual hatch...lol but how can you tell? like if its manual or obd-whatever

 

PR4 - B18A DOHC (90-91)

Looking at the pinout for the PR4 I would say its for a OBD0 LS w/manual tranny

I'm not sure if that other crap even means anything...

Well the harness plugs are a dead givaway as to what OBD it is. Also, looking at the pinout I don't see anything listed to control the auto tranny so I'm pretty sure it's gotta be for a manual... though I don't know much about OBD0 ecus.

I can post the pinout if you want..

Dammit... no more trying to be usefull when tired. Sry

 

ECU number should read 37820-PR4-### - the ### will tell you whether it is for manual or auto

5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00
Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80, L50, L51

the OBD0 and OBD1 PR4 ECUs have different plugs

 

thanks...is there any way to repair ecus? or u jus throw em in the trash lol cuz this is chipped and when it was working good DAMM what a power difference, and im a broke *** college kid.

What is the problem you are having? Get good pics of both sides of the circuit board for us...
