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 0-4 volt output to enable connection to a data logger or an ECU to provide real time closed loop feedback for improved fuel mapping. 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.
- Programmable alarm to warn you of dangerous lean condition
- Peak recall of leanest value during the last run
- Selectable for all fuel types with AFR from 6:1 to 20:1
Supplied complete with a heated Bosch LSU 4.9 sensor (plus stainless steel mounting boss) and a wiring harness.
