Default Wide band help

Do most of you guys leave your wide band hooked up all the time, or just put it in to tune. I have HPT will be putting on LT's and think I will tune it then pull the sensor out when its running right.

I plan on leaving my PLX R-300 in place(in Z28) once I am done tuning my V6. I have been reading feedback on forums and guys are getting 50k to 75k miles out of them....well lets see I drive my car about 6k to 8k miles a year. Lets just say I am not worried about having to replace the sensor any sooner than I would have to normally.

We use custom portable widebands that we made for street tuning, and have the same widebands permanently mounted in our shop cars, In my experience the sensors in the ones that are permanently installed last longer

Seen a lot of people with LC-1s complaining about sensors
having short life. I use my LM-1 every few months and it
is still on its first sensor. They want some preheat before
you start throwing wet oily exhaust at them and key-on,
take off, is not going to help them out. I vote for accessible
bung and only when needed. Mine is welded at 3 o'clock at
the trailing edge of the passenger's door, in the I pipe. It
doesn't need me to lift the car at all to swap in & out, and
the cable comes through the door and is held snug by the
weatherstrip to keep it off the pavement.

leave it in for good. maybe on your guys' car, but on my lowered vette... getting to the center of the car to locate the sensor even when the car is jacked up, is a challenge.

i have a plx too.

When I'm not tuning my car, I prefer not to have the LM-1 controller sitting around in the car, and having to remember to switch it on and off.

The sensor is in the tailpipe after the turbo, so it's pretty easy to get to. Wiring goes up through a rubber plug in the spare tire storage area.

I got about one year out of mine and then it would throw out weird numbers. Go lean go rich 20% O2 then 10 to 1.

I use it only when tuning, it's a self contained box that plugs into the bung I have welded and plugs into the rear O2 sensor.

I have mine permanently installed, but I run open loop all the time, so I need it to monitor what is going on. My LC-1 is still on its original sensor, and it has been in there for three years, but is no longer daily driven.

Are you going to be running open loop? If not, then the only reason to keep it in is if you are wanting to monitor a/f constantly. I kept mine permanently in the car was because I was always monitoring everything.

It was a plx m300 and never gave me a problem for over 15k. However, I replace my sensors that are used for tuning purposes often because they flake out after they've been used on different types of applications for extended periods of time.

So you close the door on the cable?

I must be lucky as I am on my 3rd year of running my LC-1 all the time and it works great, I race with it and drive with it on the street, I start the engine then turn the LC-1 on

I have the dynojet one, not sure what sensor that is but it has about 8k on it so far and works fine, hopefully it will stay that way. I prefer to leave it to always monitor...specially with the spray.
