The DDECII ECM was a single box mounted on the engine.
The DDEC II Engine was available in ratings up to 450 hp (340 kW) and 1,450 pound force-feet (1,970 N·m) of torque. The engine proved extremely popular with fleet operators, and built a strong reputation for reliability and longevity. It was also available in a popular "cruise power" configuration, which encouraged the operator to engage the cruise control function. During the normal use of the engine, 405 hp (302 kW) would be available, and when the cruise control was engaged the horsepower rating would increase to 425 hp (317 kW), as the engine was the most economical whilst the cruise control was engaged.
