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.

 

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).
