Can an ECU from a 1975 280Z be used in 1976-78 280Zs? Are the ECUs from the 1975-78 280Zs interchangable?

Thanks,

From my experience, you can use the 75-76-77 interchangably but since the 78 doesn't use contacts in the AFM to operate the fuel pump it stands alone. Also you can use an MT ECU in an AT car but not the other way around because the AT ECU is missing pins #20 and #21.
