What is Lambda anyway?
Lambda describes an equivalence value in percentage of the chemically correct air-to-fuel ratio for any type of fuel. If the air fuel ratio measured in
the exhaust pipe of an engine is at the chemically correct (stoichiometric) ratio of air-to-fuel, lambda is equal to 1.0. In the case of gasoline, lambda
1.0 is equivalent to 14.7:1 air-to-fuel. Lambdas less than 1.0 indicate the engine is running richer than stoichiometric, while lambdas greater than 1.0
indicate a lean mixture. If we measure a lambda value of 1.06 and we want a lambda value of .95, we simply increase the fuel delivered to the engine
(pulsewidth) by 11 percent. is will place us exactly at .95 lambda. By using the Lambda Was or the Quick Lambda functions a tuner can quickly
shape the fuel table to match the engine’s exact requirements.
How long will the Lambda Sensor Last?
A Lambda sensor is designed as a consumable item which means like a spark plug, it wears out with use. Typically you may notice the sensor begin
to slow down in its response to changes in lambda when it becomes worn out. is normally occurs in about 500 hours on unleaded type fuels but is
reduced to 50 hours for lead. Like Spark Plugs, the sensor can be fouled in a matter of minutes with improper air fuel ratios and the sensor can crack
if it is over torqued or dropped. For this reason, there is no warranty on Lambda Sensors.
