Wide Band Air/Fuel Sensor

[BigDog05]

Anyone run a wide band air/fuel guage last season? I'm wondering about the life expectancy of the Bosch sensor.

I just installed a Dyno Tune Wide Band LC-1 on my sled and the sensor lasted about 20 minutes. I ran the sled twice on the stand to make sure all the guages are working properly and get a base line for my stock pilot jets. Bender recommends going to the smaller pilot jets on their stage 2.

Guage went to a reading of 50 which indicates that the sensor went bad.

Talked with Dean at Dyno Tune and he is sending me a new sensor, at a discount price, and they will test mine and send me a free one if Bosch determines it is a bad sensor. Everything is installed properly.

I realize that leaded gas will shorten the life of a sensor, but are these sensors going to be too sensitive for snowmobile environment.? Hopefully I just got a bad one.

The Bosch sensor will die almost immediatly with race fue. NTK all the way!!

Thanks for pointing that out. I read through their tuning manual. They recomend sensor calibration every hour when running leaded fuel :shock: . That's alot of time spent dicking around with the system (taking the sensor out and calibrating it).
