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).
