All,

Decided to make a new post. In this thread I will document everything needed to get an EMS-4 running with my 94 miata. Thus, this is tailored for a 94-95, but with some checking you will be able to modify for any year.

So I just got done designing the wiring harness. I can't give away the key file for the program used (don't try to enable macros), but I can share the resulting spreadsheet. I don't have time to explain exactly how to read this, but it is not hard to figure out. Blocks are connectors, each line is a wire, and the line contains all info about said wire.

The picture is so you can reference the pin numbers for the stock miata (Braineack I think made it).

Future posts will talk about building the harness, base map, and startup/config notes.

Thanks!

 

Man this thing is being a PITA to get running. I may have cam/crank pickups swapped in the wiring diagram. Other than that all reads well, just can't get it to actually run yet. Stay tuned...

 

The cam/crank is easy to figure out. Pull the cam pigtail and watch the counters on the advance pickup tab on AEMTuner.

 

Just an update, Got everything working except the damn fuel injectors, it just seems like they are not firing. Ill see what I can do this weekend...
