The fuel, ignition advance and other internal combustion elements are controlled by the ECU. The role of the ECU is to monitor the inputs of these operations such as gear position, throttle position and rpm. The ECU flash is the internal storage area where the data required for ECU functioning is stored. The ECU flash can be switched on or off without erasing data. Data flash which is the area where the variables (such as constants, maps and curves) reside and are referred to by the software when needed.ĮCU flashing, also referred to as tuning, updates the software that runs your vehicle by changing or modifying the vehicle’s memory chip in the ECU.Program flash where the entire software code resides, and is responsible for controlling logic.The ECU flash can be segmented into two main areas: In order to reset the memory, it will need to be reprogrammed and tuned. These changes can notably improve your engine performance by improving power, producing cleaner emissions and bettering fuel efficiency. When manufactured, a vehicle’s ECU will usually be programmed with standard settings and certain safeguards in mind. In some cases, the performance of a car may be restricted in order to fit certain class criteria, or protect the engine from potential damaging effects and neglect. Optimising your vehicle’s ECU settings can massively improve power and fuel efficiency, while still keeping the durability and longevity of your vehicle as a priority.
Different types of ECU FlashingĮCUs can be calibrated in several different ways, depending on the purpose of the ECU flash. Remapping a vehicle’s ECU can reduce the cost of running a vehicle. This purpose of tuning is particularly attractive for businesses that prioritize fuel economy and keeping costs to a minimum. Remapping for economic reasons has been known to demonstrate a fuel efficiency increase of 10%. Other drivers seek a drive that is more riveting.
