Tomohawk asked in another thread about modules that might swap in to the 1978 280Z, from other models or brands of car.

 

Here's one possibility - http://datsun1200.com/modules/mediawiki/index.php?title=B-210_Electronic_Distributor_Swap

 

I haven't figured out if the modules are the same in the cars listed or just other parts, but it's a start.  Of course, most of these cars are just as hard to find in a junk yard as the 1978 280Z.  That's the main problem, everybody only used the big box for a few years before everything got small.

 

I used a 78 module in my 76 car for quite a while, by building a simple terminal panel to allow the wire ends of the 76 to be input to the plug of the 78.

Here's the control module info broken out.  Notice that four and six cylinder are the same.  So there's a list of old hard-to-find cars to look for in the wrecking yards.

The GM 4-pin HEI module is also an option, but its not plug and play. Some basic knowledge of the systems and the possibility to fabricated mounting plates etc.

 

Changing over to a 280ZX distributor is also an option. Amazon sell remanufactired units for around $120. http://www.amazon.com/Cardone-31-619-Remanufactured-Import-Distributor/dp/B000C46L52

It would need alterations to the wiring, but it is possible.

 

Edit: Found these two on E-bay. Not cheap, but it is plug and play so to speak.

The LX-511 is basically the Californian model for the 76-77 280Z

The LX-512 is the FED model for the 76-77 280Z with the dual pickup.

I only started this for Tomohawk's question about a direct module swap.  It's interesting though how fast the technology changed.  From 74, with the big box under the dash, to 79 with the matchbox on the distributor, then to ECU timing and dwell control in 81 with the turbo engines.

 

I've always wondered about the timing curves for ECU control.  Not so easy to figure out what the ECU is doing, and no specs. published like with the distributor control.

 

Nissan doesn't even try to explain it, they just leave it unknown.

I have a spare 77 TIU I was planning to rebuild with a HEI module and make available as an exchange unit. That would make it a plug an play mod for people not confident doing the mod themselves, but its not economically viable with the shipping and the import duties I have to pay for parts.

If I had to do any changes to the wiring to use one of the alternatives, I think I would choose the 280ZX distributor.

You are right about Nissan not giving any details on the leter units they seem to have changes the way of informing technicians and choosing the Test and Replace black box method.
