Chip tuning modifies a programmable and erasable read-only memory chip in a car or other vehicle's electronic control unit (ECU) to achieve superior performance, whether it's a higher power, cleaner emissions, or more fuel economy.
Engine manufacturers typically use conservative electronic control unit cards to account for individual engine variations, as well as sparse maintenance and poor fuel quality. You can also look for diesel tuning services for your vehicle in Australia by clicking at:

Vehicles with redesigned electronic control units may be more sensitive to fuel quality and maintenance schedules. Modern electronic control modules can be configured by simply updating their software via a standard interface.
As technology advances, so does the electronics used for cars. The electronic control unit in modern cars, together with the advanced engine technology, allows many aspects of engine operation to be controlled, such as spark synchronization and fuel injection.
The electronic control unit can also control electronic throttle valve control (wire drive), valve synchronization, gain control (for turbo engines), anti-lock braking system, automatic transmission, and cruise control (if applicable).
Another reason for changing the map of the electronic control unit is that changes have been made to the vehicle's engine, intake system, or exhaust system.
These "bolt" modifications changed how the engine worked, often resulting in changes to the air/fuel ratio. Without re-establishing the fuel table, some of the performance improvements due to those changes may not occur.
