https://docs.emtronaustralia.com.au/engine-management/config/ignition/ignition-mbt/index.htmlOverview Selects the ignition table that represents MBT (Minimum Spark Advance for Best Torque). MBT is defined as the ignition timing that produces the maximum engine torque for a given engine speed and load operating point. Additional ignition advance beyond MBT will typically provide little or no increase in torque, while ignition timing retarded from MBT will result in a reduction in engine torque output.Hugoen-us
