I'm calling bullshit on this. IAT is a small part of a large fuel equation where MAP and O2 values are the primary determining factors for the fuel curve. Simply lying to the PCM with IAT values will not significantly effect the curve. Think about it - what happens when you dump more fuel into the cylinder? You get less oxygen in the exhaust stream, right? The O2 sensor sees this and passes it along to the PCM where the fuel curve is adjusted to maintain the 14.7:1 stochiometric air-fuel ratio. Basically what will happen is that the PCM will adjust the long term fuel trims to compensate for the false input. You can go to Radio Shack and buy a twenty-five cent resistor that will do the same thing.
