Re: iat sensor

You bought a performance chip for your car that involves the IAT sensor?

That is sending me a red flag right now. Please tell me it is not a resistor mod. Those are SCAMS and will damage your engine!

Any reputable chip, like SCT, plugs into the PCM which is located under your dash usually.

The performance chip you bought is probably nothing more than a $.10 resistor in a box to change the value of the temperature that the ECU thinks the intake air is. It simply makes the ECU think the intake air is colder than it actually is therefore richening the a/f ratio, which will probably also cause a drop in fuel efficiency. The IAT sensor is located in the air intake tube.
