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.
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.
