Hey all, pretty new to this whole Miata thing. Going to be turboing mine this Summer as I get more free time, so I've decided this month I'm going to do the whole DIY MS thing to prep for the forced induction.

If I get this https://www.diyautotune.com/product/...th-black-case/ what all would I need to finish it off?

I've done a lot of soldering and assembly in the past so I'm not too concerned with that part, just want to make sure I have everything to make this work with my '00 MX-5. I also read in another thread that it was figured out how to make the MS3 standalone and work with A/C, but it didn't say how and I haven't been able to find out after searching around a bit.

What is the MS3X needed for? And is it better to piggyback the MS3, or standalone (with ac etc working)? I still can't find much information about making it work, just people talking about the issue being resolved

At this point, you want an ms3x as a stand alone unit. I would not try to piggyback it. If you want a piggyback I'd pursue other options. The ms3x is pretty much what everyone on here recommends. Folks have also had good luck with the diypnp. The MS3X is fully able to control the ac and alternator etc.

There are some differences between those two, but I'm afraid that I'm not the right person for that info.

There are a few threads on here that deal with that information. You might want to read the stickies before folks start yelling at you!

Read through the stickies before I posted, maybe I glazed over the answer to my question on accident :-p

I was meaning the expansion card when I said the MS3X.

Thank you for the info and the site suggestion, by the way; really appreciate it! Excited to get the turbo show on the road

Assembly instructions on my site. You could also use a ms3 pro module with one of my boards;

OP, I would listen to everything this man says on the subject.

Is your site the trubokitty one? I wasn't seeing a DIY MS3 Pro board on the diyautotune site. Just want to make sure I'm getting the best ECU together I can right now for my car.

Thanks again for the input everyone, appreciate it!

Trubokitty is braineack's site.

Westfield's site is in his signature.

uBlock Origins (my adblocker) was blocking all the signatures on the site, thought they were adverts for some reason... Didn't notice until you said that

The module is a bit hidden on their site, but here's a direct link.
My instructions and Brain's are pretty much the same, we worked on them together. The biggest difference is that I install the tyco connector inside the case, but if you don't like that, just ignore that part of the instructions and make a traditional wiring loom.
The instructions were written for newbies, but some things are so obvious for 'us', that they might still be unclear in some areas. So don't hesitate to give feedback on them here.

I was actually just trying to find a PCB w/ components and/or a schematic, to make my own versus purchasing a premade

That won't work with the MSPRO. But the MS3X can be purchased as a kit from DIYAUTOTUNE. I'm a bit surprised you haven't found this yet.

I'm not sure if you are looking for opinions on whether to build or buy, but I figured I would weigh in since someone else may read this. In summary I would buy the bare ms3pro board w/ adapter that frank sells or the ms3pro. Read on if you want more detail.

I built an ms3x with knock using frank's instructions. The only issue with it after building was a missed ground, which took some effort to diagnose. It has worked ever since. However, if I had to do it again I would buy a ms3pro. This is based on:
The final cost is about the same as diy (close to 1k once built to the same level as the ms3pro).
The difficulty in troubleshooting a non-standard build. Every problem requires an overview of your assembly first.
The robustness of the ms3pro is far better than a diy box.
Future proof HW setup, change the car and only change the harness.

I found the MS3 kit from DIY, I just wasn't able to find the MS Pro board in the same unassembled state - that was moreover my question, trying to figure out if there was a set with a compiled bill of materials and components to make the pro version, before I went and bought one to make the 3

The PRO is a surfaced-mounted PCB pre-populated from the factory...

It's kinda why the MSPRO is not categorized on the diyautotune.com website under Megasquirt kits, but under Plug and Play Solutions.

what you can buy is JUST the PCB, and then Frank's adapter board will allow you mount it inside a OE ECU Case, along with all the additional circuits needed to run a miata.




I REALLY HATE HAND HOLDING. so I'm really posting this passive aggressively to point out how bad you are at searching

here's the problem:

PCB + MAP sensor - $125
https://www.diyautotune.com/product/...0-partial-kit/
MS3 CPU - $219
https://www.diyautotune.com/product/...hterboard-kit/
Case - $40
https://www.diyautotune.com/product/...odized-case-2/

total: $384

PLUS Components list:
Assembly Guide - MegaSquirt(R) V3.0 Main Board


vs.
https://www.diyautotune.com/product/...th-black-case/

full kit will all the components you need (plus more) $385



I fee like you need to spend 3 minutes and read...

I think maybe I was misunderstood - I know where to source the full build for the MS3 and to follow the instructions. Someone in this thread recommended I look at the Pro as opposed to the MS3 - I was wanting to assemble my own to save money, and I was unable to find the Pro in unassembled form. If it really is a better ECU (which I still am learning about) I would rather etch and drill my own and assemble it with a bill of materials and sourced components. Otherwise I would still use the MS3 kit on the site; I guess now I know that it is a pre assembled version.

Wasn't really asking for hand holding, was just trying to figure out why it is advantageous - I have read the stickies in this sub forum and done some googling but it still isn't 100% clear.

The PRO is not designed to be an assemble your own, but it still needs to be made to work in a miata.

like look at the MS3 PRO Module:


What Frank was suggesting was a Pro module, plus buy his adaterboard kit which makes it a PNP unit that fits inside the OE ECU Case and has all the suppliment circuits needed:

Otherwise, you'd buy the v3.0 PCB MS3 kit + expander board, and essentially build the same thing...

etching your own; come on man... the v3.0 PCB kit IS the assemble your own and save money approach.
