Buy Engine Control Module | ECM | PCM | ECU

The Engine Control Module (ECM) also known as the Powertrain Control Module (PCM), Engine Control Unit (ECU), or simply Auto Engine Computer (Automotive Engine Control Module) is the brain of the car. Not having a good working (electrical control unit) / ECM is a serious problem in keeping your vehicle running. Some of the signs that should alert you about having a non-working PCM are when your check engine light comes on, high idle speed your engine is misfiring, your engine is stalling, noticing a decrease in performance, and last but not least your car is not starting at all. The majority of our Engine Control Modules are Plug and Play (Plug 'N Drive) units that will not require any additional programming. Browse our range of engine computer module now!

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 to process all of the incoming data from various different position sensor but not limited to just that. I.E the ECM checks with the the body control module once the car starts to make sure that the VIN is the same on all the other modules and whether security should be activated or not. Ensuring that your auto ECM module is running up to its optimal performance is of paramount importance.

The auto electronic control module rely on these control systems and vice-versa :
Air Flow Sensors : translate electric current to digitals readings that in turn tells the PCM amount of fuel it should inject in the first intake stroke , making sure that the airfuel ratio is optimal and not stress your engine load. 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. Word of advice always clean your throttle bodies every once in a while and save a trip to the shop.
Spark 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 sometime be altered. Which work amazingnly well with all variable lift systems.
Cruise Control : This is more of a function that heavily relies on the PCM for signal, when you start cruisuing the PCM constantly check your speed and driving conditions of your vehicle. SImiarly it also affects the electronic valve control but only in Koenigsegg engines.
Transmission Control : The ECM constantly communicate with the TCM to gather data from the brake pedal position sensor / electronic throttle , the turbine sensor and the transmission fluid temperature sensor. If you have kept up with your scheduled maintenance or recently made a trip to an auto repair shop and have had no sign 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 representative to inquire information on whether your ECM can be repaired by us or if a an ecm replacement is inevitable, even if the circuit board might look fried it is worth a check!
