Can a motorcycle's ECU be replaced?

[McNadia]

Motorcycle's ECU can be replaced. ECU is the central computer: The ECU of an electronically fuel-injected motorcycle serves as the central computer. The electrical circuits of electronically fuel-injected motorcycles have achieved high integration, intelligence, and systematization. The entire wiring system functions as a unified whole, where all electronic signals from various subsystem sensors converge to the central computer. After calculation, these signals are then distributed to the actuators of each subsystem to perform their tasks. Functions of the ECU: Fuel supply function, ignition control function, fault diagnosis function, and basic expansion functions. Current electronically fuel-injected systems installed in vehicles operate under closed-loop control. This means the ECU determines whether combustion is normal by detecting the oxygen content in the exhaust via the oxygen sensor, thereby deciding the fuel injection pulse width to precisely control the fuel injection quantity. This is a crucial method for enhancing the engine performance of fuel-injected motorcycles and improving fuel economy.
