In some cases, an economy remap may be able to deliver fuel efficiency increases of 10%, meaning that they provide an excellent return on investment. If you’re running a business, have a large commercial fleet, or just want to reduce the running costs of your vehicles, then you can choose to have an ECU remap to significantly improve fuel economy, helping to keep your fuel bills to a minimum. Different types of reflashĮCUs can be calibrated in a number of different ways, to suit the individual requirements of different vehicle owners.

Generally, stock ECU settings hamper the performance and economy of an engine, and by optimising them, you can improve power and efficiency without compromising the durability and longevity of your vehicle. In addition, some manufacturers artificially restrict performance to ensure that a vehicle fits into a certain class to suit fleet buyers and the company car market. This is because ECUs are programmed with in-built safeguards designed to cover the use of substandard or lower octane fuel, and to protect the engine from the damaging effects of neglect – like leaving it too long between services. When manufacturers build a new vehicle, they programme the ECU to certain set specifications, but in the vast majority of cases - these aren’t the optimum settings. This process is known as ECU remapping, reflashing, or sometimes ‘chipping’.
#What is an ecu flash software
Like any computer, the ECU has software with different settings, and these can be changed to alter the performance and driving characteristics of a vehicle. The engine control unit, or ECU, is your vehicle’s on-board computer, and is responsible for controlling a number of different engine functions, including the ignition timing, turbocharger boost pressure and fuelling.
