....as the topic says im trying to buy a obd1 manual ecu... is there anything to look for in the ecu that will say its for a manual tranny? how do i know if i test drive the ecu if it is a manual or not?? thanks for the help...

 

hey man, don't really know what to say about this, but I'd like to know how you can tell if it's auto or manual ECU

bump

 

thanks katman

 

Doesn't a manual ecu have 3 spots for the harness to plug into, and doesn't a auto ecu have 4, someone correct me if I'm wrong.

this is true for 96 and up ecu's
92-95 will either have a 5 between the ecu Id

 

ok lets say we got a P28 there are 3 sets of numbers on the bar code

on the last set there are 3 digits, the middle one tells you

0- Manual 5- AUTO

 

just out of curiousity, does anyone have anything that tells you what all the other numbers on an ecu are????

 

Since the auto has those 2 chips in there, can you convert it to manual by taking them out??

which ecu are you getting? 92-95 civics/integra/etc are obd1...plugs of the ecu have only 3 slots for the 3 grey plugs. 96-98 civics, 96-99 integra's are obd2A. 99-01 civics, 00-01 integras are obd2B. Say if your getting an obd1 p28 ecu, the numbers will say 37820-p28-A00 (A01, A02)...the last 3 numbers/letter indicate which year the ecu is, as well as auto/manual. In the case of A00-A02, that means its a 5 speed ecu. If it said A51, A52, G52, etc...its an auto ecu. This mainly applies to the obd1 p28 ecu. I believe the integra's might be the same as well...Not exactly sure how to read the year by the number indicated....post what the lable says on the ecu and i could find out for you... 37820-**-*** Let me know, also...if you drive w/ the ecu and you get no codes, then your fine

 

found it:

in 88-91 ecus (PM6, PR4, PW0, PR3, PM7):
5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00
Auto = J51, J50, A50, A51, 900, 901, A60, C50, C51, X30, A80

92-5 ECUs (P28, P30, P61, P72, P91, P08)
5spd = 000, 001, 002, 003, A00, A01, A02, C00, C01, C02, J00, J01, J02
Auto = J50, J51, 900, 901, 902, C50, C51, C52, A50, A51, A52

96-00 ECUs (P2E, P2P, P2J, P72)
5spd = 000, 001, 002, 003, A00, A01, A03, C00, C01, C02, C03, J00, J01, J02, A11, C11
Auto = A70, A71, A72, A91, A92, C70, C71, C72, C91, C92

from the patterns we can learn the following:
first letter = country of orgin
J = Japan
C= Canada
A=USA
second digit, if 5, 7, 9 then ecu is auto usually
third digit denotes the version/variation

 

thanks for the info

 

thanks for the info on how to ID the ECU

 

thanks a lot you guys... the picture had clearly shown what is a manual an AT... this is rather informative to for everybody...

 

does the version number matter? i have a 91 integra 37820-pr4 A0_
obdo would the version nuimber have to be a 0 or does it matter?

 

How do you tell which ecu you have & the numbers are peeled off?
