ok the number on the side of the ecu is

37820-P72-A02-970-108377

does this mean he has the 94-95 P72 integra GSR ECU? on a 1st gen b16a? is this bad could it be hurting him?? makin him to run rich - any of you ecu junkies out there help him out thanks
BTW his name on this board is blackhatchb16
Thanks
Brian

 

p72 gs-r ECU

 

yea, hes got a gsr box, he should replace it with a chipped p28/08

 

what ECU is the P28/08? - where can he get one at?

 

92-95 civic vtec is a p28 and i think the p08 is the jdm version.

 

where can he get one at?? - is it plug-n-play, ie unplug old ECU plug in new one?

no
if this is in an OBDI car or the first gen was converted to OBDI you need a p30 ecu, from a DOHC del sol vtec or JDM SiRII.

you can use a chipped p28 but thats alot of hassle, its easier to just get a p30

 

here is a quick ID:
a quick pic in ID'ing a 5spd to auto ECU or just ECUs in general

OBDII (96-01)
P72 : 96-00 OBD-2 Integra GSR
P73 : 96-00 OBD-2 Integra Type-R (JDM & USDM)
P75 : 96-00 OBD-2 Integra LS/GS
P2N : 96+ OBD-2 Civic HX Coupe
P2P : 96+ OBD-2 Civic EX Coupe

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, 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, 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

hope this helps
