#Ecu flash full#
Significant improvements can be achieved by correcting the stock ECU's deficiencies and tuning the engine to take full advantage of its potential. The result of this is often a compromise resulting in sub-optimal performance. Stock ECU's generally are far from optimal and are developed to allow for a wide range of riding styles, fuel quality and operational conditions.
#Ecu flash code#
ECU ReFlashing, in general terms, is a method of erasing the ECU’s program code (instructions) and reprogramming the vehicles ECU’s Flash Memory with altered program code, thereby changing how the ECU will respond to inputs. The term “Flash Memory” refers to a particular type of EEPROM that has a fast erase and reprogram time of its internal storage. Most ECU’s have a main memory storage system that is comprised of a nonvolatile Electrically Erasable Programmable Read-Only Memory device called an EEPROM. All of these output responses from the ECU have to be predefined in ECU’s internal memory. In general terms, the ECU is primarily responsible for monitoring and managing the engine's performance via a number of sensors and then calculating the proper signal to send external devices to control the operation of the engine. Most modern engines are equipped with a microprocessor-based computer referred to as the Engine Control Unit or Electronic Control Unit which is abbreviated to ECU.
