The engine control unit (ECU) controls the fuel and air mixture in modern engines. The ratio or "mix" determines the performance as well as the efficiency of the engine.

The control unit configuration has given rise to the art of chip tuning performance, whereby the machine settings can be manually adjusted for various driving applications. You can also look for ECU services and chip tuning in Australia via https://refineddieselremapping.com.au/.

The control unit uses a power card to achieve the best settings for normal machine operation. Changing the efficiency map leads to changes in efficiency and performance.

For road applications, setting up an ECU engine typically prefers an efficiency map that uses less fuel and air. The effect is fuel savings.

For competitive purposes, the chip adjustment will promote more fuel and air. However, the ratio varies depending on ambient conditions and the efficiency of the spark.

The algorithms that determine the mix and the spark supply are what differentiate one engine control unit from another. Control devices are not limited to road vehicles. Most modern means of transportation, including motorbikes, motorbikes (trucks, semi-trailers), earthmoving machines, scooters, buses, trams, and even golf carts, use motor control modules.

They are usually metal boxes, which are close to the size of the average novel. In addition to controlling performance summaries, they were recently designed to record events. This gives various authorities the ability to capture and analyze these events, turning the control unit into a kind of black box recorder.
