Your vehicle’s ECU, or
Engine Control Unit, monitors the different components of the engine and alerts you if something isn’t working properly. If your vehicle’s ECU is faulty, it can prevent your engine from functioning as it should, and cause a host of other problems.
UpFix technicians can expertly restore an engine’s functionality and prevent future problems by repairing ECU, ECM, PCM, and FICM units. (These units are all same but have different names: ECM = Engine Control Module; PCM = Power Control Module; FICM = Fuel Injector Control Module) Our ECU repair services extend to both local Atlanta customers and nationwide customers through our mail-in service.
