The Stack Wideband Lambda Gauge is a very useful tuning aid with a digital and LED display providing an accurate real time readout of either air/fuel ratio or lambda. The gauge has a 0-5 volt output to enable connection to a data logger or an ECU to provide real time closed loop feedback for improved fuel mapping. The gauge is also supplied with a serial data output. An alarm is featured to give a warning of dangerous lean fuelling which can lead to engine damage. The leanest value can also be viewed by using the peak recall facility. These gauges now come with with a programmable display response so you can fine tune the sensitivity of the gauge
