Stack Wide-band Air-Fuel (Lambda) Gauge

Wide-band Air-Fuel (Lambda) Gauges This is the ultimate tuning aid! Dual digital and radial LED displays provide accurate real-time readout of either air/fuel ratio or lambda (user-selectable). A 0-4Volt analogue output can be connected to a data-logger or to an ECU to provide real-time closed-loop feedback for improved mapping. Supplied complete with wiring harness and includes Bosch sensor.

• User-selectable Air/Fuel or Lambda real time display
• Programmable Alarm warns of dangerous lean condition
• Peak Recall of leanest value during last run
• Suitable for all fuel types with AFR from 6:1 to 20:1 (not recommended for leaded fuel)
• 0-4 Volt Data Logger or ECU output
• The product can be used with the following fuels: Fuels Stoichiometric Air/Fuel Ratio - 
• Unleaded Petrol 14.7:1
• Methanol 6.4:1
• Ethanol 9.0:1
• LPG (Propane) 15.5:1
• CNG 17.2:1

Stoichiometric Air/Fuel Ratio is the chemically correct ratio where theoretically all the oxygen and all of the fuel are consumed. The mixture is nether rich or lean. Note: The product is suitable for use with Nitrous oxide (where legal).
