Turbo gauge, Trionic T7
The main instrument unit is equipped with an electronic turbo gauge.
This gauge is supplied with current and controlled by the main instrument unit's control module.
The value shown by the turbo pointer is based on the following: Trionic T7 calculates the air mass/combustion and converts this information to a value between 0 and 255. Trionic sends this as bus message "Turbo gauge". The value corresponds well with the engine torque.
The main instrument unit uses this value for the turbo pointer, which informs the driver of the load on the engine.
