As the Intake Air Temps and Engine Coolant Temps rise, the ECU begins to pull timing to protect the engine, thus slower 1/4 mile times. These sensors are really nothing more then resistors that change the signal as temps rise and fall. By replacing the sensor with a fixed (or variable) resistor you can clamp the signal to a constant level - thus the clamp tells the ECU that the IAT is always 70* (or what ever you choose) and not pull timing regardless of how hot the temps get.

It's OK racing short distances - not good for long distances - unless you have a separate IAT sensor/gauge and monitor the temps manually.
