Nissan ECUs from 1975 to 1989 (pics)

All of the ECUs lined up here. That's my old 1976 N/A California ECU in the upper left corner, my 1981 Turbo Federal ECU next to that, my 1984 Turbo Federal ECU on the bottom left, and Jason's socketed 1988 N/A ECU on the right.

Oh and BTW, the 1976 ECU doesn't control the spark.

The 280Z did feature "fully transistorized ignition", which was in a seperate control box on the passenger side of the interior.

ECU Evolution :P

Look how many more resistors are in the new ones

I have to wonder how the '76 one even works. It looks so dumb and basic.

Supposedly, someone tried to pull the tune off of one of those '81 ECUs, but I don't know of anyone doing it successfully.

Wow, that is really cool to see how the hardware changed over the period where EFI made the largest leaps in its childhood. I would really like to see how operation was refined (besides the obvious old AFM vs newer MAF). Now you just need a couple Z32 ECU's and a Z33 PCM to round out the collection :-D

Wow, I didn't know that. Talk about the early days of electronic fuel injection!
