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 is the ignition timing on a Peugeot 106?
its set by the ecu
How do you sit timing on 2.0 Ford Contour?
The ignition timing is controlled by the ECU, and is not adjustable.
How do you check the timing on a 97 Ford Contour?
The ignition timing is controlled by the ECU, and is not adjustable.
What is a timing connector connected to?
A timing connector is typically connected to components in electronic or automotive systems that require synchronization for operation. In electronics, it links to timing circuits, microcontrollers, or clocks to ensure proper signal timing. In automotive applications, it may connect to the engine control unit (ECU) or ignition system to manage timing for ignition and fuel injection. Overall, its primary function is to facilitate coordinated operation among various system parts.
Will a bad ecu cause no spark?
Yes, a faulty engine control unit (ECU) can lead to a no-spark condition in a vehicle. The ECU is responsible for controlling the ignition timing and firing the spark plugs; if it malfunctions, it may not send the necessary signals to the ignition system. Additionally, issues with the wiring or connections related to the ECU can also contribute to a lack of spark. However, it's essential to consider other potential causes, such as faulty ignition coils, crankshaft position sensors, or other components, before concluding that the ECU is the issue.
How do you adjust the ignition timing on a 92 Scoupe - non turbo?
You cannot adjust timing its done in the ecu
How do you adjust the timing on a 1995 wrangler?
There is no timing adjustment on fuel injected models the ignition timing is set by the ECU . Regards:
Does ecu control firing and fuel on 92 Toyota truck?
Yes, the ECU (Engine Control Unit) in a 1992 Toyota truck manages both ignition timing and fuel delivery. It processes data from various sensors to optimize engine performance, ensuring the correct amount of fuel is injected and the ignition system fires at the right moment. This electronic control helps improve efficiency, reduce emissions, and enhance overall drivability.
Where is the ecu unit on a rover 75 and what is it?
The ECU (Engine Control Unit) on a Rover 75 is typically located in the engine bay, mounted on the left side near the battery. It is a crucial component of the vehicle's engine management system, responsible for controlling various engine functions such as fuel injection, ignition timing, and emissions control. Accessing the ECU may require removing some covers or components for better visibility.
What is an ecu on mini cooper?
The ECU, or Engine Control Unit, in a Mini Cooper is a critical component of the vehicle's engine management system. It monitors and controls various engine functions, such as fuel injection, ignition timing, and emissions control, to optimize performance and efficiency. By processing data from various sensors, the ECU ensures that the engine runs smoothly and meets regulatory standards. In modern Mini Coopers, the ECU also interfaces with other vehicle systems for enhanced functionality and diagnostics.
VW Ahu engine need an ecu?
Yes, the VW Ahu engine requires an ECU (Engine Control Unit) to manage its operation. The ECU controls various engine functions, including fuel injection, ignition timing, and emissions. Without a functioning ECU, the engine may not run properly or at all, as it relies on the ECU for optimal performance and efficiency.
