Automobile manufacturers must compete in a marketplace where fuel consumption, horsepower and torque are big factors, but they must also comply with emissions and other regulations. To meet these demands modern cars are controlled by computers. The computer, known as an ECU (Engine Control Unit), controls all engine settings like the air/fuel mixture, ignition timing and idle speed. A quick and easy way to do this and upgrade your vehicle’s performance is with a “superchip”, also known as an aftermarket performance chip. Aftermarket performance chips are made to adjust parameters to increase engine power and torque. The effects of the superchip can be easily reversed just by plugging it into the ECU and choosing the reset option, which will cause the ECU to revert to the factory settings. Overall, upgrading your ECU settings with a superchip is a fairly simple and low cost alternative for the everyday auto enthusiast.
