How Exactly Does Chrysler Concorde ECM Perform?

By Rommie Leighton


One of the most efficient types of ECU or Electronic Control Unit found in Chrysler Concorde unit is definitely the Chrysler Concorde ECM or the Engine Control Module. It is an electrical program installed inside the automobile. It's most often known as as PCM or Powertrain Control Module.

The ECM/ECU regulates virtually all the major functions the engine automobile offers. It handles the ignition timing, air/fuel ratio, idle speed, electronic valve control, also the variable valve timing. These are just the few features of ECM/ECU of the Chrysler Concorde car that preserve its performance and running condition superb.

An Engine Control Module can adjust the perfect timing of your spark (ignition timing) in order to initiate combustion in the combustion compartment to promote and provide economy and stronger power towards the ignition engine. The Chrysler Concorde ECM can detect knock, a situation that is possibly harmful and destructive on the car's engine.

For the air/fuel ratio function, the ECM or what we normally call ECU, will figure out just how much fuel to inject based on parameters. It possesses sensors, known as mass flow sensors that measure the additional air that is being drawn into the vehicle's engine and the ECU/ECM will add more fuel towards the engine. The other sensor that it regulates is the engine coolant temperature sensor, which tends to make certain that the engine runs significantly "healthy" until it warms up.

Almost all the vehicles have idle speed control installed into the ECU of their engine systems. The RPM of the engine is monitored by a sensor which acts as a main function inside the engine timing operations for spark events, valve timing, and fuel injection. Complete control of idle speed also offers top speed limitation and cruise control features.

The electronic valve control allows your engine to handle the exhaust and intake valve opening, location of valve opening, as well as the valve closing. Some trial engines have been tested which have no camshaft but still have complete control on the electronic valve. The other one is the variable valve timing which the ECU/ECMU regulates the moment the valves open in engine cycle. This would optimize the course of air into the engine's cylinder, increasing economy and power.
