Trionic
Trionic is one of Saab Automobile developed motor control system consisting of a control unit (engl .: engine control unit is, ECU) which controls the three motor aspects:
- Ignition ,
- injection
- Regulation of the boost pressure .
Hence the ingredient ' Tri ' in Trionic. 'Ion' comes from the fact that a stream of ions is used in the cylinder to detect ringing , knocking and synchronization.
Since Trionic 7, the throttle has also been electronically controlled, but the name "Trionic" has not changed.
Projects
In various open source groups around the world, attempts are being made to analyze the Trionic motor control system using reverse engineering . The aim of this work is to interpret the binary files stored in the control unit and to understand which changes affect the vehicle and its operation.
