DFI Control System: Description

The Digital Fuel Injection system (DFI) is an advanced speed density system that combines engine control, fuel metering and emission monitoring into a computer-controlled system. The Electronic Control Module (ECM) is the "brain" of the DFI system. The ECM is a digital electronic computer which receives and processes engine data, computes and interprets engine information and signals operational instructions to various components to provide fuel efficient operation of engine with reduced exhaust emissions.
