This brilliant dashboard mounting unit monitors and displays your car's air-fuel ratio in real time on a three digit display and at the same time on the programmable 10-LED bargraph. Indicates ratios between 11.8 - 20.6 for petrol and 12.7 - 21.5 for propane/LPG. Some features: fully lean and fully rich indication, fast 220ms update time for bargraph, 440ms upgrade time for 3 digit display, 0-1V display for setting up adjustment, dot or bar option for bargraph and auto display dimming for night driving. All this in a compact case measuring only 83 x 54 x 31mm. Leaded petrol engines will soon poison an EGO sensor, so it is recommended that kit be used for tuning purposes only.

It costs more, but I like it because I can "see" a number, so I don't have to interpret "the bouncing lights".
