Aftermarket/ Relocated IAT sensor?
So I've been reading alot about the heatsoaked stock placement IAT (intake air temp) sensor and have decided to move it to the cold side intercooler piping when I build the SMIC setup.
Now, What I haven't been able to find is anyone who has done it and showed the specifics.
What sensor did you use?
What calibration did you use? (assuming you have a PFC)
thanks guys!

Theres a guy on the forum that sells the fast-reacting IAT sensors. I bought one and put it back in the stock location and it works great. Temps change very quickly with no heatsoak.

Here's the fighters garage one:

but it doesn't say where the sensor came from or hw to calibrate it.
I was thinking more like a GM IAT sensor. Or an aftermarket MSD one like this:

The sensors don't really need to be calibrated. Just plug 'em in and go.

I'm running the dudemanrx7 fast acting IAT sensor too. Don't have much to say because I've only run my car for ~20 minutes since installing it but it definitely seemed to work better than the OEM unit. I would just go that route.

Maybe I'll just call Apexi and see which sensors are compatible.

See that just shows how much people don't know about engine management. Now, I don't know a WHOLE lot but I know these sensors have certain ranges they operate in and the scales they arc through based on voltage they read is what tells you that say .87 volts = 37C or whatever. Things need to be calibrated. Period.

Go ahead and call Apexi . . . lol I want an exact transcription of that conversation. I'd like to think it goes something like this...
You: What kind of IAT can i use on my RX7?
Apexi: You should speak with someone that knows RX7s.
You: I did. I told him that he didn't know what he was talking about.
Apexi: . . . *click*

ok... I just finished installing mine about 30 min ago... spliced it in, works awesome!! Reacts waayy faster then the OEM on, i got it to about 12Celcius out here right now in Cali on the freeway in about a 5 mile drive
no need to calibrate ANYTHING!

I'm sure there is a scale and offset calibration value for the IAT sensor that is contained in the PFC (and the factory computer). It could be changed to accommodate whatever sensor you want, including the inexpensive GM sensors. But that requires disassembling the EPROM and reprogramming it, something that is common on many platforms but not this one.
Thus you have two options. You use the stock sensor or you use one that has resistance values that are very close to stock.

Dudemaaanownsanrx7 (Brent) sells them on his web site, wannaspeed.com. if you pm him he could give you the link to his thread on here with all the data you need. And as said its plug and play. Rix
