I've been doing some research but I haven't seen anyone asking the same question that I have.
So I have a '93 miata with a '97 1.8 motor.
I plan to go turbo soon so I want to megasquirt it first to learn the software.
My question for you is which ms is best for me?
I don't know whether I go with the 90-93 mspnp and get the 1.8 tune for it or if I go with the 96-97 mspnp.
I basically just don't know if the ms are differentiated by the wiring harnesses or what. Right now I still am running it on the 93 stock ecu.
Any help would be appreciated.

 

You buy the MS based on your chassis. So in your case you would buy a MS that works for a 90-93. You would just make some changes to the tune to work for the 1.8 engine.

 

Awesome that's what I figured.
Thank you

 

and by mspnp, i hope you mean mspnp2.

 

And by mspnp2, I hope you mean Brain-Built MS3X.

 

This is the correct answer.

 

Well I was going to get the pnp2 but I've never seen the MS3X.. Any of you guys know where I can get that and what the difference between it and pnp2 is?
I'm clearly new to this

 

it would be the difference between a MSPNP2 and a MSPNP-Pro.

 

Alright cool so I'll look into the mspnp-pro thanks guys

 

My suggestion would be to read all the stickies at the top of the MS section.
