https://docs.emtronaustralia.com.au/engine-management/tuning/fuel/lambda-target-tables/index.htmlOverview The Lambda Target table enables the user to define the desired Lambda target across the operating range of the engine. The Lambda Target is a primary input to the ECU airflow and fuel model and therefore directly influences the final calculated fuel mass injected into the engine. Once the Engine VE (Volumetric Efficiency) table is correctly calibrated to achieve the commanded Lambda Target, the engine’s operating Lambda can be adjusted simply by changing the Lambda Target value, without requiring changes to the main fuel calibration.Hugoen-us
