There are 2 ecu's that I have a choice between buying, both are p28 vtec ecu's.

my problem is the guy selling them does not know which one is auto and which is 5-speed.

the numbers after the p28 are a01 or a51.

if anyone can help out as to which is the 5speed and which is auto please do.
thanks

 

cmon some one has to know.

 

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, P0
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

 

no shit.... auto or tranny ecu doesn't matter if chipping? does that only apply to a manual car or will an auto car work with a manual ecu if chipping?

vapor, I take it that the chipping also includes rewritting weather or not the veh is manual? and I would assume that this applies to hondata also, since it is more than just normal chipping.

si-r trickery what country code is the letter G, I have seen it on a few ecu's?

 

bump

 

I have never heard of a "G" code

 

I'll take the Auto P28 LMK whats up mang!
