Default 99 miata. Questions.

First.
i have a 99 miata, 1.8 non vvtI .
Non turbo but that is the plan.

I got a ms2 2.2 ecu used for 75$
It's for a rx7 and has a rx7 expansion card.

​​​​​The parts I know.
wire my 37 pin to my 76 pin.

What specific things will I need to do to swap it from rx7 to Miata.

Will I need the eBay Miata altinator card? Any info would be nice. Am I missing anything?

Thank you!

You're doing it the hard way.

I would use the correct computer for the job.

But if I needed to control an alternator I would just swap to an NA8 alternator that uses an internal voltage regulator.

Sounds like a $75 lesson.

Maybe, but probably not. Resale on the ecu is around 300, it's a rx7 ecu, if all else fails I'll sell it... Could be more.

I should explain myself a bit better.
I'm in no rush to make this work right away. Im in the far northeast and I can't drive my car for... 4-5 months?

My thoughts are this so far. I could buy the 76 pin breakout board and densso style connector, and plumb that in. I'm not sure how to add on the 2nd 37 pin, but it looks like a daughter board. The other option is to take the 2 37 pins and wire it to a connector from onlinecompents.com

For the altinator, there is an addition board you can buy that fixes the volitage regulator issue. I'm looking for the right parts to buy.

Also. I'm very handy with electronics and soldering. I'm still learning about megasquirt and the challenge is the part I like. I didn't just want to buy a pnp. That is no fun for me .

Thanks

Sell now. Put the $225 profit towards something that isn't terrible and will work easier for your car. Profit.

Sounds like you like doing things the hard and really stupid way with low chances of success.

You'll fit in great here.

The real secret is to keep the blue smoke inside the wires.

You forget the challenge is what I'm looking for, anyone can go buy a pnp, and yea that is cool, but honestly not what i'm looking to do, I don't care about just plugging it in and working, I want a better understanding of the board in general.

It also looks like you can just make it run ignition and timing, and fuel , and that will work just fine, more like a piggyback. that seems interesting as well.

I get you like to talk **** and looking at all your old posts you seem snarky etc. Again, fine, but not what i'm looking for. You haven't once explained any facet of the Ms2 v2.2 installation procedures. Why would I avoid it when no one can tell me what parts are missing or why its a bad a idea, from my research, a 99 Miata boom sling might be a great idea? I'm looking for solutions, not insults.

I don't think you looked at all my old posts. I have a lot of them.

Thanks for the reminder that I dodged a bullet by not interviewing at Maine Med.

You realize that you can buy a board as just parts and do it yourself right? Doesn't have to be pnp...
