https://docs.emtronaustralia.com.au/engine-management/functions/engine-start-control/index.htmlOverview This function controls both Engine Starter Function output and Immobiliser Function. The Engine Start Function will switch an Output ON to start the engine cranking. The ECU Output would normally be connected to the Starter Relay. Once the ECU determines the engine is running the relay will be switched OFF. NOTE: Both an Input and Output Channel MUST be selected for the Engine Start function to work.Hugoen-us
