Nedá se to třeba vyčíst přes notebok ze seriové lambdy? Ví někdo kolik má seriová lambda rozsah díky?

z této stránky:AFR's
I have both wide and narrow band sensors to check AFR's. Stoichmetric, 14.7:1 is equal to 0.638V on a typical narrow band sensor, not 0.5V. I have cross checked voltages against an M&W Uego and Haltech Uego and found the following of typical NTK and Bosch narrow band sensors.
0.78V - 13.5:1
0.82V - 13:1
0.85V - 12.7:1
A cat. and lamda equipped 205 stays between 0.6V and 0.9V under ALL conditions, except on overrun.
The best way to check AFR voltages cheaply is with an old analoque multimeter and a narrow band sensor. Digital multimeters read too fast. Failing that, buy a 0-1V panel meter. If not that, a 0-1mA panel meter and put a 100Kohm trimpot in series with it. Calibrate the meter off a known low voltage output (flat AA cell) so it reads 1V at full scale deflection.
Go for a drive and aim to keep the full load voltage between 0.8 and 0.9V. Anything less than 0.8V is too lean at full load.
