how can i tell whether my ecu is for an automatic or it is for standard is there any way to find out by reading the numbers on the ecu or not please help me out here.

 

on automatic ECU's there is usually an extra plug (4 plugs) on OBD1. I'm not 100% sure on OBD2.

 

a quick pic in ID'ing a 5spd to auto ECU



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

 

thanks im sure it will help, although i know for a fact there is something else very very wrong with my car
