What Can Car ECU Remapping Do?
Car engines today are embedded with a software program known as the engine management system. In short this is known as ECU. When cars are manufactured and distributed globally, the manufacturers set a default value within the engine management system.
This value is set according to the rules and regulations of the particular country to which the cars will be exported along with other factors such as the climatic conditions of the geographical area. However, in some cases they may fail to meet the requirements of a particular car owner especially if he is a racing or modification enthusiast.
Another thing to understand is that the ecu remapping of these cars is not set for its maximum performance since they have to follow different kinds of regulations. As a consequence you cars performance is limited although it has the potential to do much better. In such cases the best thing to do is to go for ECU remapping which will reprogram its engine system to deliver optimal performance according to the climatic conditions of your territory.
If you go for professional ECU remapping you will find that a specialist tuner will make use of an OBD flash tool to edit the engine control unit. He will set it to a value that will give you maximum power and torque along with fuel efficiency. ECU remapping diesel engines and petrol engines varies accordingly and hence you need to be aware of the manner in which this process is conducted on your particular car.
