https://docs.emtronaustralia.com.au/articles/tmf-idle-speed-control/index.htmlFor idle speed control, users often try to manage engine speed by manipulating throttle position to control airflow. This works reasonably well with solenoid systems (ICV), where position has a more proportional effect on airflow. With DBW — especially on larger throttles — small changes in throttle position have a disproportionately large effect on airflow, making fine control difficult. Emtron addresses this with a purpose-built approach. TMF (Throttle Mass Flow) Idle Speed Control is a specialised function that provides superior airflow control at idle by working directly in mass flow terms rather than raw position.Hugoen-us
