Chris, I don't quite know how to say this, but welcome to Thunderdome. (Or, at least, the internet version of it populated by e-thug nerds.).

Without knowing the year of your car, we're totally unable to help you. This is part of why the natives are stomping on you.

The other part is that there are only a couple of different reputable vendors of MegaSquirt hardware, such as DIYAutotune, all of which are easily found with a few minutes on Google.

2 May enter, ONE MAY LEAVE!

 

for one of the noobiest.

 

While they do come up for sale here, it's also worth looking at the Miata Parts for Sale facebook group. One popped up yesterday, although I don't know if it's still available (or works for your car).
