Question Re: Autotune 02 Sensors
I recently read that the 02 Sensors have a limited life and that if you get them wet they are toast.
I've had mine connected for a couple of years and still they seem fine.
Getting mine on and off the rear head-pipe is an absolute B-Itch.
Any comments appreciated.

Define "get them wet".
I have ridden through several monsoons with no issues. I do agree that getting getting the rear one out after 4 years is a real pain. I finally ended up having my Indy pick up the bike and had them do it when mine died last year.

Below is a link to the article that mentions getting them wet will ruin them. I just happened to be searching for information regarding the Autotune unit when I came across it. I know this guy is not talking Harley specific but I doubt that would have any bearing on how well they hold up.
I also could not find anything on the Dynojet website or Fuel Moto's either, regarding whether or not to keep the Autotune unit on indefinitely.

Do you mean your sensors died? If so is it possible that those "several monsoons" had anything to do with that?

Considering that the sensors were 4 years old with well over 20,000 miles on them and that I had not ridden in the rain in the recent past. I feel very comfortable stating that I do not believe riding in the rain hurts them.
I will have no qualms about riding in the rain in the future!

Auto tune Sensors...
if you are running the 18mm bosch sensors (which come w/ the pc autotune ) and installing them them in the stock location,,,the aftermarket sensors are a good bit longer than the stock narrow band sensors ...and that may be way so many have problems installing and removing these sometime...
i read the article you link too ...but i dont understand disconnecting the auto tune module...by doing so ...you have just turned your smart auto tuning motor into a dumb carburated motor ...
because ...one day may be high pressure air w/ very dry/low humidity ...and the next may be just the opposite ...low pressure and very high humidity...it adjust for these changes ...so why would you want to disconnect it after you think the bike is "tuned" ..to save the sensor life ...well tires ware out ...fuel pumps ware out ...light bulbs ware out ...!!! guess what you do when these things ware out !!!...

the "wet" issue has to do with moisture condensing on the sensor tip inside the pipes. that is why Bosch recommends a 10-degree up-tilt of the wideband sensor when installed so the sensor tip points slightly down, and no moisture can pool on the tip.

well I just went through hell trying to figure out why my auto tune would not work on my new to me 07 roadking classic. bike run like crap idled even worse. narrow it down and confirmed it was bad O2 sensors. power vision will let you read the voltage levels and tell you what they are doing. both were dead in my bike.
as far as getting the old sensors out, I got the sensor socket but it was still a bitch. someone cranked those things on there pretty damn good. the sensor socket would not work so I just cut the wires off the old sensors and used a regular socket and a breaker bar. new sensors in and the heavens parted the cloud and the bike screams again and the auto tune works..
