https://docs.emtronaustralia.com.au/engine-management/functions/lambda-control/lambda-control-wide-band/index.htmlLambda Control - Wideband All Emtron ECU’s can support closed loop wideband lambda control using various methods. KV series ECUs have two internal wideband control systems that allow the user to wire lambda sensors directly to the ECU. In addition to this, Emtron ELC (Emtron Lambda to CAN) devices may be connected over CAN networking (included in all Emtron ECUs), and even an external Lambda controller that has a standard AV output can be used.Hugoen-us
