Also, to be clear, this is the thread that really threw me off when it came to the IAT.

https://www.miataturbo.net/megasquir...ow-what-76953/

From Post 5 in that thread, which is a quote from instructions from rev on the MS3


"7. If you want to use a GM IAT sensor, it must now be wired in.

• On the 99-05 (Non-MSM), simply replace the stock air temperature sensor found
"
But then the last post in that thread


"If it's like my 2000 model, it's pretty simple. Run a vacuum line off of a T at one of your existing lines. Install and wire-up your WB. Unplug and remove the factory ECU, and plug in the MS3 and zip tie it up under the dash. You should be able to use your factory IAT sensor, but if you want to place it with the GM part that's a superior sensor. Start the car and begin tuning/tweaking with tunerstudio."

I found a similar list of instructions which DID mention the IAT, but those were for an MS3 Basic, which I don't have, and I assume following instructions for a megasquirt that's not the same as mine is a quick way to blow stuff up.

I will continue to dig through the forums at DIY and MSextra, and I also discovered that there are some decent tips in the "making and installing your own MSPNP" thread which I originally overlooked as I thought it was strictly for the soldering/construction of the MS board, which I'm not doing.

The IAT is a universal standard across the MS. I kinda sympathize for you as sometimes info get mixed around but the IAT is one of the many staples of having an MS.

trust me, you don't wanna use the stock ait sensor unless you are n/a.
to get any sort of proper reading, it must be in the pressurized piping not the inlet

that's on nb's

on na's to retain the stocker you have to retain the stupid maf. so that's even more fail.

so pretty much everyone uses the gm iat

so I need this one: MSPNP and DIYPNP IAT Sensor Kit - Aluminum Bung DIYAutoTune.com which comes with an aluminum bung, and then I need to find someone who does aluminum welding to weld that into one of my charge pipes downstream of my IC.

18psi 01-14-2014 03:54 PM

yup.
or you can drill/tap the coldside end tank and screw it in there requiring no alum welding

mlev 01-14-2014 03:58 PM

You all rock. Becomming a site supporter is on my "parts list". There's no way I could do this without mt.n

Technically yes, but it's much easier to drill and tap the thick aluminum on the cold side of your intercooler. That's what many of us do, and requires no aluminum welding and you can save a few bucks and get the no-bung included AIT sensor.

Edit: too slow...

Thats what I did plus you can use the same 3/8ths tap you are going to use to tap your oil pan.

Its a win win win. 1 win for no welding, 1 win for no heat soaking and 1 win for being resourceful and not spending extra monies.

Because you weren't confident enough in your knowledge to know that your friends are functioning vegetables.




WOW this thread moved fast. I'm late. Does everyone still love me? Ok good.
