Supported Wideband Controller

The processing of wideband O2 sensors is a very complex task and not handled by the DIGIFIZmini hardware. Various devices from different manufacturers are available specifically for this purpose. Most of the wideband controllers available today provide the measurement data in digital form at a serial port. The DIGIFIZmini wideband O2 gauge evaluates this digital data and displays exactly the transmitted value, any imprecision is depending only on the used measurement system. Because each manufacturer uses a proprietary format to transmit the measurement data, a DIGIFIZmini wideband O2 gauge can only be used with the selected wideband controller.
