It uses several sensors on the engine. Crank posistion,knock sensor and what happenes is if the readings say there is a knock because of something like bad fuel it will send a comand to the ECM to either advance or retard the timing. the crank sensor tell the ecm were the crank is during rotation.

What does ECU stand for?
Electronic Control Unit (ECU) controls the fuel injection system, ignition timing, and the idle speed control system. The ECU also interrupts the operation of the air conditioning and EGR systems, and controls power to the fuel pump (through the control relay). The ECU consists of an 8-bit microprocessor, random access memory (RAM), read only memory (ROM), and an input/output interface. Based on information from the input sensors (engine coolant temperature, barometric pressure, air flow, etc.), the ECU determines optimum settings for the output actuators (injection, idle speed, ignition timing, etc.).

What you mean by ecu of Yamaha yzfr15?
Forget the Yamaha YZFR15 here... ECU stands for 'Engine Control Unit' and controls factors such as ignition timing, air/fuel ratio and in more advanced engines factors such as variable valve timing, exhaust butterflies, water injection etc. Pretty much all modern engines are controlled via and ECU instead of by mechanical means.
How do you set ignition timing on a 1994 jaguar 4.0 engine?
Ignition timing and advances are all computer controlled (ignition amplifier and ECU)based on info from several sensors. No mechanical or vacuum advance at the distributor, and moving it will not change anything.

Where is the ECU located in a Volvo 240 1990?
Most 200 series Volvo share a similar design. Both the Ignition and Fuel Injection Electronic Control Units (ECU) is located behind the outside passenger-side kick panel. To get to it, remove the plastic panel and the overhead insulator, the Ignition ECU is mounted on the firewall, and to its right, the Fuel Injection ECU.
