What are the inputs and outputs of the ECU?
Inputs & Outputs _ Explained 1. ECU Engine Control Unit Inputs & Outputs By: Kamel Elsayed 2. MAP sensor المنفولد ضغط حساس • The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine’s electronic control system. • Engines that use a MAP sensor are typically fuel injected.
How does the engine control unit ( ECU ) work?
The readings from this sensor are then fed back to the engine control unit (ECU), which uses this data to adjust the fuel injection and ignition timing. On some vehicles the sensor may also be used to switch on the electric cooling fan. The data may also be used to provide readings for a coolant temperature gauge on the dashboard.
What do you need to know about programming an ECU?
Programming an ECU typically requires interfacing the unit with a desktop or laptop computer; this interfacing is required so the programming computer can send complete engine tunings to the engine control unit as well as monitor the conditions of the engine in realtime. Connection typically used in this interface are either USB or serial .
What are the rules for the ECU unit?
Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere. The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.

What do you need to know about functional relationships?
If you’re looking at a graph, you don’t need to see exact numbers to be able to describe the relationships you’re seeing. You can simply look at patterns of behavior. And in fact, even if you do have exact numbers, learning to recognize these patterns of behavior will help you recognize functional relationships more quickly.
How does ECU measure the working state of the engine?
ECU shape size. 2.2 Working Principle ECU judges the working state of the engine through the sensor measuring data acquisition and calculation. ECU performs Optimization and control tasks according to the existing and stored calibration data. 3 Technical Parameters
Where does the ECU data come through on an Evox?
Pin 103 from the ecu actually comes through to pin 8 on the OBDII vehicle connector. K Line Data (used for recovery mode ecuflashing) Pin 80 from the ecu actually comes through to pin 7 on the OBDII vehicle connector. Abnormal correlation between manifold absolute pressure sensor and barometric pressure sensor
How does the Rover 14CUX fuel injector system work?
Most notably, the 14CUX system included an auxiliary module to assist troubleshooting by displaying numeric fault codes (as shown below). Also, the 14CUX system came with a newer generation of Bosch fuel injectors which provide more power and approximately one mile per gallon better fuel economy.
How are sensor data used in the ECU?
While this is going on, the oxygen sensor takes readings from the exhaust gases to determine how much fuel to add with the fuel injectors into the combustion chamber. The ECU uses the camshaft and crankshaft position sensors to determine where the pistons and valves in the engine are at any given time.
What happens if O2 sensor is malfunctioned?
In case of too rich injection control, poor acceleration is happened and color of exhaust gas is black. If ECU detect malfunction of O2 sensor, engine vibration and poor acceleration is disappeared.
