I am looking for a wideband stand alone Air Fuel Sensor that will help me tune my supercharged carburated 13B.

I like the Zeitronix but all the sensors I looked into indicate that the life of the sensor will be affected by some fuels. They read: "Using the O2 wideband O2 sensor with leaded gasoline, two stroke or diesel engines will significantly shorten the sensor’s life."

I was told they are affected by the mixed oil/fuel. Is this true?
What sensors are you guys runing?

Any help will be appreciated.

FYI. Below is a picture of my set-up. It is a 13b with a Camden Supercharger installed in a VW Karman Ghia.

 

The Bosch sensor seems to be the most commonly used O2 sensor. Since I can't picture you running leaded or diesel fuel, and all rotary fuels have some degree of pre-mix, pick the sensor that's the best match for your unit and budget.
