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 vehicle. Not having a good working 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, 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 ECU module units now!
