I'm sorry if I missed it but I still can't find an answer to the 2nd question in my previous post. Namely, do pins 1, 9, and the pin for the A/C fan EACH have 2 wires connected to them? Or do each one of these pins ONLY connect to 12v?

 

<p></p><p>As I said. You don't connect them to 12v. That makes no sense. Those are outputs.</p>

 

Got it. Thanks for your guys' patience.

 

<p></p><p>This is what you need to focus on. Frank's guide has a lot of semi-out dated info.</p><p>Thanks for bringing this up. Its going to save me a lot of time wiring diodes tonight.</p>

 

What are the details of #4? Built a MS3 per Westfields instructions. Just updated the MS3 to above #3 mod. Getting ready to put in a '00 NB. I have his alternator board as well. Just checking if I should do anything else differently from the original setup?

 

If you are using his alternator board no need for step 4. Just wire field on his board to spr4 amd then add spr4 to the harness like his diagram has.

 

why the **** would you use his alternator board or build the circuit?

ms3x supports alternator regulation.

 

<p>I'm using it because I'm building this megasquirt for someone who wants **** to be easy and doesn't want to mess around with it. I haven't played with alternator control so I'm not going to give it to him.</p><p>(Also the board was included in the kit he bought)</p><p>If it was me I would try the alternator control.</p><p>All these questions you ask are because Frank's guides are outdated, yet they are the only &quot;step by step&quot; guides to building a megasquirt.</p><p>MS3x seems easy to you, but when you don't know what anything is and you just buy from DIY autotune, franks **** is what everyone goes to.</p>

 

<p>Uhm, for realz?&nbsp; Did you open up the 200+ page MS3X V3.0 manual?&nbsp; And yes, I would use the on board alternator control.&nbsp;</p>

 

<p>I did. I used it. I built my megasquirt.</p><p>I'm telling you why people use franks guides. It is the &quot;Miata Megasquirt building for dummies book&quot;.</p><p>Once you actually do some more reading and research then it becomes obvious, but a lot of people don't get that far. I know when I built my first megasquirt I didn't know what half the **** was, I just followed the steps. I've since learned a lot more.</p><p>Just explaining it from a noobs point of view.</p>

 

<p>What I don't understand is why people follow 3rd party--and often old, wrong, and outdated--build guides instead of following the published manuals.&nbsp; We were begged to produce comprehensive .pdf manuals.&nbsp; It was a big endeavor.&nbsp; We did it.&nbsp; And no one reads them.</p>

 

<p>I read them, if that makes you feel any better </p><p>Because people want it easy. A lot of people build their own to save money, they don't want to learn they are just cheap. I started out that way, then realized I actually wanted to understand stuff.</p><p>Also, you gotta realize this **** is confusing. I have a degree in electrical engineering, with a lot of focus on embedded programming and devices, and I struggled at the beginning (some would say I still do)&nbsp;its just a different level of stuff.</p><p>Pretend you didn't know what a resistor does and follow the guides, its not easy.</p>

 

<p>I mean look at OP Ben, he doesn't know how a fan output works. (No offense to OP). He had the diode wired in a way that renders the output completely useless. And potentially sends 12v where it might not want to be.</p><p>You work on megasquirt for a living, some people have art degrees&nbsp;<img alt="The Brain" src="https://www.miataturbo.net/images/smilies/the_brain.gif" style="height:32px; width:32px" title="The Brain" />. I tried to help a kid install his megasquirt the other day, and quit, because he just didn't care about understanding how it worked. Started freaking out when it wouldn't idle right. And this was an MS3 basic, I had to talk him out of building his own.</p>

 

I helped frank with his guide, but like ben said, part of the problem was keeping up.

I publish all my information, but it's hard to stay up-to-date. that why i didnt bother writing my own.

Then the next problem is, people start referencing old docs as bible. and you have people doing old out-dated methods of things. like building the Abe's VR conditioner circuit, or people pulling the SIG_START fuse when unnecessary, or adding in random diodes, lots of references to MS1 stuff.

frank's guide is pretty good for little hints and time-savers, but it's pretty outdated on a few accords at this point, and I still dont like the integrated harness thing.




basically, what it all boils down to is that im lazy.

 

Im not blaming anyone. Just explaining why.
<br />I hate the integrated harness. And I built line like that. Someday I will redo it.

 

dont lie. let's fight.

 

Don't even joke, I would kick your ***.
