what are all the ECUs that are compatible for the Mazdaspeed miata 2004

 

all of them

 

^ what he said. They're all PNP. All you need is one of these:

 

MS Labs is the droid you are looking for.

 

Wire in, or plug and play?

 

I happen to have an AEM EMS4 for sale, would be willing to sell without the harness, you can get a PNP harness from Boomslang.

All?!

Sure, let me compile a list...

 

I remember when I started my search for an ECU about a year or so ago. My head was spinning with all the terms and options when I tried to start researching. What finally helped me was a table someone put together summarizing all of the options and their capabilities. Not sure where that is, but I'm sure if you search you will find it.

To make sense of it in my feeble mind, I lumped them into categories:
-Megasquirt (MS Labs, MS PNP...)
-Not megasquirt (AEM...)
-Flyin Miata (Hydra)
-Piggybacks (forbidden)

I'm sure there are others out there that fall outside of these categories, but I eliminated them based on lack of support or capabilities.

I ultimately picked Megasquirt 3 by MS Labs. It's an amazing product in finish construction and capability. Unfortunately it's user (ME) isn't up to the same capability level as the ECU, so I'm having some problems with it.

It really wakes up an MSM though. Good luck.
