GM IAT Sensor Placement Help - Mitsubishi Evolution Forums: Mitsubishi Lancer Forum

Greetings

I am going SD and have the Omni 4 Bar with a GM IAT Sensor. After searching the forums, I can't seem to get a definitive answer on where the IAT Sensor is supposed to be welded on. I have read on the forum that the placement goes before the BOV. My question with this is the placement for a Tial 50mm VTA BOV: Members have the sensor welded before the BOV between the IC and BOV, but the shop I am getting to weld it on is saying that it should be as close to TB as possible. I understand the the IAT reads the temp of the air, but will placing it before BOV throw off readings for air in UICP after air is vented?

I don't plan on using Meth in the future. I plan on staying on pump gas for a while.

Any help on this matter please?

im not sure on this one. this is a questions for the tech gurus hopefully they come on and check it out. i would copy what works though if people are getting better results before the BOV then go with that. Also why are you going with a speed density setup? what mods do you have?

so what is your goal of running GM setup? Personally with a intake you can hear any recirculated BOV, if thats your goal. I would have just gotten a different BOV and not even worried about the rest. i understand if your running crazy amounts of boost with a big turbo and a stand alone, but for everyday use i would just keep it running the mafs and tune the ecu with ecuflash.

Yes, I'm planning on running a SD setup as well and the sensor must go as close to the intake manifold as possible. Most people would put it right on the intercooler pipe, just before the throttle body. I would just get one of these hobart welders and weld the sensor pretty close to the throttle body, on the IC piping.
