I rode in a coworkers turbo miata. Less than a month later I bought this stock NA. It is a 1994 C-Package (Torsen!). When I bought the car I also bought an MS3 with MSX board from the seller of the car. He said he had it running on this setup but ended up buying an MSM instead.

Pretty much immediately I installed a Mishimoto radiator (I was paranoid about my green OEM radiator). I also threw on some RPF-1s I had left over from my racing days and installed a Hard Dog roll bar I picked up on Craigslist.

Next came an AEM UEGO. It still had the stock ECU at this point because I wanted to see what OEM AFRs looked like.

Now I am ready to install the MS3 but am running into some issues. I 3D printed this replacement for the OEM MAF, but I am not sure where to plug the GM IAT leads. My factory service manual shows the 5 wires coming from the MAF, but it does not show what 2 are for the IAT. I also read the MS3 hardware manual, but obviously that is not specific to Miata. Any suggestions?

Well there use to be one. I just checked every subsection and can't find it. Where did it go Miataturbo?
Not the one I was looking for, but found this..

You are right though, if it were PLA it would not hold up for long.

why even bother to delete the MAF? (and replace with a 3d printed pipe?) when i installed my MS2 to learn it before i went turbo, i just unplugged the MAF and drove like that for month's.

Keep an eye on it. I've run ABS 3D printed parts on my car and they are disposable maintenance items. They all had cracks within a couple track days. It looks like your part has a thicker wall then what I used but you are also closer to the header than my part was. Keep a close eye on it and print a spare to keep in your trunk if you plan on racing it.

I do a lot of 3D printing and am experimenting with ABS. Some of the motivation behind making this part is so that I can see for myself how ABS performs in an engine bay.
