do I have to hook up this air sensor(IAT sensor) when running a turbo? I don't want any check engine lights come on. One guy told me he just left his sensor wire tied under the hood. Would that work? Right now it is hooked up in my aem cold air intake tube(as seen below)

 

I asked this question yesterday and Some people said to just tap it into the charge pipe. But i'm wondering if you have to run it at all....or if it will throw a check engine light on.
I also found this post on here. Anyone know the best thing to do with it?

yes... tap it into the charge pipes... it is needed

 

i let mine hang in my bay, it's not really NEEDED, it needs to be plugged in, and if you want your **** to work properly you should have it in the charge pipe or change out to the manifold mounted one like on the GSR's

 

from all the info i gathered in my thread. it is very important in a boosted application. this is a direct quote from a well respected tuner.

this is what i asked

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by me &raquo;</TD></TR><TR><TD CLASS="quote">i just got a jdm b18b, on the intake manifold there were 2 sensors missing. one being the IAT, the other not sure what its called but it sits right on top, next to the map and tps sensor. well i figured out what i needed to do with the one by the tps and map sensor.

but there is no place for the iat on the new jdm manifold. right now i just have the sensor hooked up outside the manifold from the old motor. no check engine light!!!!

well obvioulsy this is a temp fix. what can i do long term? i will be boosted soon. using neptune as my ems. is this somthing i can bypass</TD></TR></TABLE>

this is what he said

right before this i asked him if it was possible to bypass the IAT sensor with NepTune


<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by servion &raquo;</TD></TR><TR><TD CLASS="quote">No, but honestly, I would never ever bypass the IAT for any speed density car. The reason is that the air temperature is an integral part of the equation that the ECU uses to calculate how much fuel to give the motor at any given time. Without that reading, you can be pig rich one day and dead lean the next.... its a really big deal.

The best way to handle your situation is to put the IAT into your intake/charge pipe about 6" away from the throttle body. That is actually much better than in the manifold anyway because then you don't have to worry about heat-soak from the head and manifold affecting the IAT reading.

If you ahve any other questions, feel free to ask!

I agree. That is a very important sensor on a boosted car or any performance car for that matter. Especially when running bigger injectors. I have mine plumbed in right before the TB, like servion suggested.

 

thanks integra fopr that reply. I will defenitly rin it in my charge pipe.thanks
