DDEC II Advanced Electronic Diesel Control 861110

DDEC II (Detroit Diesel Electronic Control) is an advanced technology electronic fuel injection and control system for diesel engines. New technologies in microprocessor electronics are used, allowing a fuel-cooled engine mounted design.The DDEC II design provides expanded capabilities with improved performance, and benefits in both cost and reliability. This system, using the new GMSCM (General Motors Single Chip Microprocessor), has increased computational speed for enhanced engine governing, on-chip functions for expanded diagnostics and communications, and I/O to meet current and future needs.EEPROM is used in end-of-line programming of basic engine ratings and customer-selected options. Engine power derating and modification of vehicle application options are also provided. Industry standardized 9600 Baud serial data links provide two-way communications with vehicle displays, diagnostic equipment, and other vehicle systems.
