Engine Control Units from Flagship One are specifically programmed to your vehicle's VIN. Your vehicle's car computer is one of many important modules that keeps your car running. The powertrain control module also known as the engine control module is responsible for processing all of the incoming data from various position sensors but is not limited to just that. For example, the ECM checks idle speed ,the the body control module once the car starts to make sure that the VIN is the same on all the other modules and indicates whether security should be activated or not. Ensuring that your auto ECM module is running up to its optimal performance is of paramount importance.

Auto Electronic Control Modules rely on these control systems and vice-versa:

Air Flow Sensors: Translate electric current to digitals readings that tells the PCM what amount of fuel it should inject in the first intake stroke, making sure that the airfuel ratio is optimal and doesn't stress your engine load which directly help fuel economy. After all fuel efficiency is something all car owners talk about at some point. Last but not least, emission control goes hand in hand with the AFS and your oxygen sensors. Last but not least the Powertrain control module play a big part with the electronic valve control to make your vehicle more fuel efficient. Word of advice, engine management is important and always clean your throttle body every once in a while to save a trip to the shop

Spapk Plugs: The engine control unit (ECU) sends out a signal to the ignition control module which in turn tells the spark plugs to ignite; ignition timing is also a key factor in this process. To take this even further, to improve engine performance and fuel economy the variable valve timing can sometimes be altered. Which works amazingly well with all variable lift systems.

Cruise Control: This is a function that relies heavily on the PCM control systemfor a signal. When you start cruising the PCM will constantly check the speed and driving conditions of your vehicle. Simiarly, it also affects the electronic valve control but mostly in Koenigsegg engines.

Transmission Control: The Engine Control Module constantly communicates with the TCM to gather data from the brake pedal position sensor, electronic throttle, turbine sensor and the transmission fluid temperature sensor. If you have kept up with your scheduled maintenance and have had no signs of a failing transmission yet you are still having difficulty downshifting and upshifting, the ECM might just be the culprit ,We are also offering ECM repair services for certain make and models, be sure to check with our sale representatives to inquire information on whether your ECM can be repaired by us or if an ecm replacement is inevitable, unless the circuit board looks fried it is worth a check!
