Lambda transducers

[Peter Douglas W]

The newest rage in Germany is to set up the PI using a Lambda transducer (those things used to save the Cat. from burning out). Has anyone out there done it and how? Secondly what are the readings they used to get optimal performance and consumtion?

Hello Peter,
the Lambda transducer gives off a voltage proportional to the amount of oxygen in the exhaust. There are two types, a simpler one which uses the heat from the exhaust to activate the sensor, the other has it\'s own heater built in.
There is a good article, and I think it was in the original TR 2000 website, which give the table of voltage from the sensor to the stochieometric value, i.e. the mixture.
I would suggest that a rolling road would be the quickest way to do the test and adjustment but they have their own mixture analysis equipment anyway. Otherwise you need to run on the road and log readings, adjust and try again.
