O2 sensor life?
Given that any O2 sensor we fit sits in a very humid environment, how long do they last on average? (Let's assume it's a decent one. (Bosch, Innovate etc).
What happens when they fail? Do they just stop giving a reading, period? Or do they give gradually worsening, inaccurate data?
Just wondered as I am gonna run the CMD on autotune and I'm interested (if not a little scared) that if the O2 fails the autotune may well read this random / inaccurate dat and lean out to destruction? Fantasy or possibility?

If u tap ur exhaust manifold it should last ... I have had 2 years and no problems but in my old RXP in the J pipe I would be lucky to last 3 months ...

2 years lol... if your real lucky
siting all winter with water in the exhaust is hard on them
and the bosch sensors are over $100
my last sensor would read normal until about 6-7000 then read 999.
if your sensor goes bad out on the water just un-plug it
that will shut off auto tune
IMO 20 point should be the max change when tuning
also after you get the ski pretty close on tune
set the auto tune to 10 point max change
so even if it goes bad you can still drive the ski

Our weather here us pretty dry here most of the year ... My skis are started at least once a week dry ...
dry exhaust ... Happy O2 sensor ...
or just remove it and keep it dry ...
I buy the sensors at a batch up of e bay and ends up costing about $60 each and all Bosch ...

2-3 years max.......and if you're using avgas maybe less. One simply doesn't know when it will crap out!

My GPRXP had the sensor installed in 2009 and still going strong ive even rode it several time with it not powered up.
