When using o/2's,on the street would I leave them on or remove when not logging. I have heard differing opinions as to the life of the sensor using all the time or when burning leaded or unleaded fuel.

As long as the heater is powered up and you are running unleaded gas, the O2 should be okay. Like Andy said, they go for many, many miles in grocery getters. But running them cold, with leaded fuels, or in overly rich conditions certainly shortens their life expectancy.
Master, again and still

Also on daily drivers the 02's run at as best a mixture as the controller can adjust to all the time. I mean when its to rich or lean the controller is adjusting all the time to try and run a perfect air/fuel mixture. But on most street cars with carbs until we tune for what ever mixture we are after it wont change and the 02 will see a rich or lean mixture all the time until we adjust the carb so I would think that will be much harder on the 02 sensors also. On our hotrods with carbs we have to make the change so the 02 may run in a not so good mixture for its life alot where on normal drivers they are running in about the best fuel mixture at all times since they are always adjusting mixture from the 02 readings so that may be harder on the 02's life. Even if the 02's have a heater I would think it will be harder on it when used in a non closed loop system. Ron

Been running the same one for several years and two+ of those was w/leaded gas and it`s still goin strong.......

Just finishing Racepak install. The o/2's also have separate wires for the heater.I'm thinkin to put them on a toggle switch,,,,,on & off. 95% of my driving is on the street so that doesn't seem to shorten sensor life.If Ican make track 4 or 5 times a year I'm thrilled. But life & work get in the way.

But life & work get in the way. With all of the money we spend on our cars, what`s the big deal about buying a $40.00 sensor every so many years. As I stated earlier mine`s fine after at least 6 years street/strip WITH leaded for the first few years and I too leave it in all of the time because carbs aren`t a "set em and forget em" deal. And as far as a toggle switch for the heater that`s crazy.............turn on the power to it, wait for the gauge to count down(if that`s how yours works)and enjoy some DIRECTION in your tuning cos that`s what it is, not the end all.

Innovate's LM-1 Manual specifically states WHEN INSTALLED IN THE EXHAUST, THE OXYGEN SENSOR MUST BE CONNECTED AND OPERATING WITH THE LM-1 WHENEVER THE CAR IS RUNNING. AN UN-POWERED OXYGEN SENSOR WILL BE DAMAGED WHEN EXPOSED TO EXHAUST GAS. p.6 If your datalogger is setup permanently, then leave the WBO2 in unless running leaded fuels. If, like me, the logger is portable, then when not using it, just remove the WBO2 and install the plug. It takes more time for me to remove the wires and T into the vac line than it does to remove the sensor itself.
