Ok I searched. But didnt really find a steady answer. Too much mixed replys. Just wondering if I should route it into a charge pipe, or leave it dangling. If I do route it.. Should it be after intercooler. Or right off the air filter. Would it reading boost temps screw up my mixture? Or would it be better to read boost?

 

keep it near the tb. it doesn't read pressure, it reads temp. the temp near the tb is where it reads stock to help in some fueling needs.

what i want to do is find a gauge that i can just tap into the wiring to see what my iat truly is.

 

You want it after the intercooler, and dangling it wont work.

i wonder why some people have it on the intake pipe...
i myself have it on the intake pipe... which gets pretty darn hot. i wonder if that is really bad. i havent had any problems so far

 

Why Wouldnt dangling work? Also what exact purpose does it serve? Wouldnt it just pop out under boost pressure?

 

If you unplug it the sensor will read the air temp as 40 degress below zero, there by dumping horrendous amounts of fuel into your motor, and making you run very rich.

What about if the sensor is still in but dangled? Wouldnt it just read the ambient temp?

 

Ohh, I see what your saying. Then it will just read whatever temp is actually there... You want the sensor.... Just keep it in.

If its not in the charge pipe it has no clue what the intake air temp is. Your IC will drastically change the air tempature that is going into the engine from the ambiant air tempature under the hood.

 

So, should you get the charge pipe taped for the IAT?

Put the IAT sensor in the charge pipe just before the throttle body or in the intake manifold runner (depending on what version engine you have. The ECM needs to have a correct signal of the incoming air temperature to properly adjust fuel enrichment.
Leaving it hang in the engine bay or unplugging the sensor is a bad idea.

In my case I was using a '00 Civic Si intake manifold (IAT in the air pipe before the Tbody) but my car is an OBD1. I used the blank IAT sensor boss located in the last runner to mount a OBD1 style sensor. Worked great.

This is a before pic, but the boss is in the right runner.

 

9psi and mine hasn't popped out of the upper pipe near the tb yet. if it does or you worry about it just put some zip ties around it to keep it in.

That is how to do it.

 

how about those with the obd2 IAT... did u guys just use a rubber grommet? any problem with leaks or it actually being shot out?

 

Man, I was just thinking about this! I used a CAI as my charge pipe and it has the IAT Sensor hole already there. I heard that it pops out under boost, but now I know what to do. Thanks guys!
