Turbo Boost Gauge: Description and Operation
Turbo Boost Gauge
The main instrument unit is fitted with an electronic boost gauge.
The gauge is driven by a stepper motor which is controlled by the main instrument control module.
The value shown by the boost gauge needle is based on the following: Trionic calculates the mg air mass/consumption and converts this information to a
value between 0 and 255. Trionic sends this as a bus message "boost gauge". This value corresponds quite well to the engine torque. The main
instrument unit uses this value for the boost gauge needle which shows the driver the load on the engine.
Diagnostics
The function has its own diagnostics in the sending system.
