I have a 2003 Miata, and I was hoping to buy a megasquirt from Braineak, but he seems to be taking a hiatus of an unspecified duration. I have started looking into building my own, but it seems like there's not very much documentation for 2001-2005 megasquirts.

The DIYautotune folks only go up through 2000; will that work for 2003 also? I'm not terribly confident in my electrical engineering skills, but I can follow directions if they are detailed enough. so I guess my questions are:

Is there a pre-assembled PNP MS specifically for 2001-2005?

If not, is there any difference between building an MS for 2000 and 2001-2005?

If yes, is there a detailed build document somewhere?

I would like to be able to run the MS in parallel with the stock ECU, just like Brain had it set up, so I don't have to worry about VVT (though I think someone mentioned to me recently that MS3 can do VVT? I haven't seen anything else about that though).

I hope this isn't a redundant question; I've done quite a bit of searching, and it seems like MS documentation is scarce for post 2000 models. If this has been covered elsewhere, please direct me to the appropriate thread.

Thanks!

Nikolai

 

Of course there is a Megasquirt for the 2001-2005; PM me for more.

 

Here you go, full instructions.
If you don't like the connector inside the case, no problem, just make a wiring loom.

That's perfect, thanks very much! I looked over the instructions for a while yesterday, and it's not as intimidating when you see all the steps laid out like that.
