IAT Sensor ?.

IAT Sensor ?.
Ive read were some here and on other forums have moved the IAT sensor from the intake manifold to the tube of there cold air intake. Are there any gains to be had by doing this ?.
Ive owned other vehicles in the past were the IAT sensor was between the throttle body and the air filter housing, and that would seem like the better place for it to be to read the colder air coming into the engine.

Doesn't really matter where you put it. The engine will adjust mixture by seeing what the O2 sensor has to say in any event. IAT plays more of a role in open loop operation. (cold engine, or large throttle openings) Having it someplace other than the stock location will have you running a bit richer, that's about the only difference.

Those "+100 hp chips" on ebay operate off the same principal. It's nothing but a resistor yuo tap into the IAT wiring to trick the computer into thinking it is cold so it richens up the mixture a bit. The gains are hardly noticeable. I actually made one for my Dakota. I could not tell a difference in any sort of power gains, but my mileage did go down like 1 mpg or so.

I moved the IAT sensor from the keg to the inlet tube (K&N) about a month before fitting an FI-Airgap, so I could see the effect of moving the sensor.
The new location is ~6" before the TB, and did not require extending the sensor cable.
The air temperature is ~50°F cooler in this location.
I saw no change in performance or MPG.
