Triumph Street Triple S - Service manual > Engine Management System

Fuel System/Engine Management / Engine Management System

System Description

The Daytona 675, Street Triple and Street Triple R models are fitted with an electronic engine management system which encompasses control of both ignition and fuel delivery. The electronic control module (ECM) draws information from sensors positioned around the engine, cooling and air intake systems and precisely calculates ignition advance and fueling requirements for all engine speeds and loads.

In addition, the system has an on-board diagnostic function.

System Sensors

Sensor Locations

Engine Management System

System Actuators

In response to signals received from the sensors, the ECM controls and directs messages to a series of electronic and electro-mechanical actuators. The function and location of the actuators is given below.
