That’s the job most performance chips set out to complete. At the end of the day, when most people think of tuning up a car, what they’re thinking of is changing the settings on the ECU. There are some special exceptions, like throttle response controllers that hook directly in line with their respective electronics. It’s this computer that most performance chips interface with, whether you’re plugging them into the ODB-II port or directly into the ECU itself.

These actuators are used to control everything from your air-fuel mixture to your ignition timing and idle speeds. This computer, known as the ECU (Engine Control Unit) – or EEMS (Electronic Engine Management System) in some cases – is what controls the physical actuators in your engine. Unless you’re behind the wheel of an old fashioned classic, odds are the engine of the car you’re driving is controlled by some form of a computer.
