Default Guide for an EMS-4 With Miata, Standalone

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.
