As Featured On EzineArticles.comEvery car has an ECU to control the performance of the car engine. ECU is Engine Control Unit. The standard performance of a car is set by the manufacturer through the ECU. Manufacturer will not program the ECU to the highest output so that the car will get the best fuel consumption.

For those who aim to race, understand that the more power you need, the more fuel you have to burn. Racer like me will not be concern about fuel consumption for the ride.

To squeeze more horsepower from the ECU, I have to cheat the ECU to push the engine to a higher explosion, to get higher output. This trick works only with Fuel Injection car and not on old car with carburetor engine.

First, you need to locate the IAT sensor of the car. IAT stands for Intake Air Temperature. The IAT sensor is the sensor that sends the air temperature signal to the ECU, telling the ECU to manage the amount of fuel for combustion. Generally the IAT sensor is located on the intake tube or somewhere before the throttle body from the intake manifold.

After you found the IAT, remove the adapter from the IAT sensor and you will see the connector with two holes on it. It looks like a normal electric plug label plus (+) and minus (-) signs. Go to an electronic shop and get a resistor of 110 ohm and plug it into the connector.

Before removing the connector, make sure your car engine is off and the key is plug out first, to prevent the check engine indicator light up on your dashboard. After placing the resistor on the IAT connector, remember to wrap it up with a wire tape and make sure the resistor is not loose and not easy to drop off. Next, cover up the exposed two holes on the IAT sensor with wire tape to make yourself feel more secure.

For your reference, Engine Control Unit also known as ECM, Engine Control Module.

After all done, time to test drive.
