A couple of questions Stein:
1) Are you currently running the stock 99 injectors?
2) You don't use COP; right? I assume you're running wasted spark.
3) Do you have any plans to run injectors in sequential mode at any time?

Here is the one I bought:
MegaSquirtPNP IAT Sensor Kit - Steel Bung DIYAutoTune.com
It is open element, came with enough wire to make the connection and the pins, plus a steel bung to weld into the charge pipe.
If you have aluminum pipes, you will need this one to get the aluminum bung to weld in:
MegaSquirtPNP IAT Sensor Kit - Aluminum Bung DIYAutoTune.com
It's cheaper than ordering parts separately.

Depending on your IC you can drill and tap a 3/8" NPT thread directly into the tank and screw the GM IAT sensor in there (on the exit side) and skip the bung entirely. You can see pictures of mine in the DIY IC link in my sig.

The serial connection is preferable to an analogue connection because the ECU can determine if the sensor output is valid by other information in the serial packet (for example, sensor temperature), and default to the analogue input (or indicate an invalid reading) if no information is available. With an analogue input, there is not usually a way for the ECU to determine if the sensor is giving valid information or not.
Because of this I wired serially.

I'd like to reiterate my thanks to Stein for an outstanding writeup. I hope he won't mind assisting me and others when it comes time for us to make our own installs.

Don't say that... You guys are trailblazers. Anything the rest of us can learn from your collective experiences will only make it easier for the next install. As time goes by, I hope to see a repository of Miata specific information... You ran into some problems and may have mad some mistakes... So what! It's learning experience. I've been reading your threads just as intently as I've read Stein's threads. Just keep info coming guys. Once I get a window, I plan on getting mine installed and document it as best I can, but first I have to deal with some TPS/heat issues. And once the car stops throwing TPS codes, I'll get on with the install.

Stein; 1 one quick question: I was rereading your install writeup and when you talk about the MAP sensor you don't specify whether you also bought it from Travis. I'd like to know if I will have to change the one I currently have (a 2 bar one from a Supra) or if I need to buy the 3 bar one.
If so; Travis: can I buy one from ebay? Which one?

It is a GM 3 bar MAP sensor.

Ok guys... I'm not sure if this question should go here or in a new thread, but here it is. I see in the instructions that y'all are using a GM IAT sensor on your IC charge pipes. In my case (a supercharger) will I still need to use the GM unit or can/should I use the OEM unit that is mounted by the air filter (SC install). If I do need to use the GM unit, where should it be installed? After the SC in the cross over pipe to the intake?
I was also wondering if it wouldn't be easier to just get a 5/16" tee with a 1/4" coming off it so you would just have to run a 1/4" line to the GM MAP unit?

The reason I went with a 5/16" x 3 tee is that I couldn't find one with two 5/16" and one 1/4" but I could find a 5/16" to 1/4" straight reducer so that's the way I went. If you can find a 5/16"x5/16"x1/4" go for it.
