WB Sensor Life - Stock Turbo Downpipe
I'm running an Innovate LC-1 wideband O2 setup full time, with the sensor mounted in roughly the same location as the original sensor on the stock 13BT downpipe. Does anyone have experience running the WB sensor (Bosch in this case) full-time in this location? Any issues with premature failure due to heat?

wideband sensors are prohibitively expensive to do this, plus for the 'shade tree mechanic' (like most of us) it's just a good diagnostics/tuning tool, and then you can let cheap sensors do the daily grunt work.
but, maybe someone here has done this.

The stock sensor is about 25 dollars for a generic, with no plug. The Innovative WB sensor is used in several VW's and goes for 75 at NAPA.
That doesn't seem prohibitively expensive to me.
The sensors last plenty long. I have only had one fail as a result of not having the unit hooked up to it when the vehicle (bike) was in use for several hundred miles.

As slo says, the cost of the Bosch WB unit isn't bad. I'd just like to know if the sensor will live long-term in the stock location, or if it should be moved further downstream to a lower temperature location.
There's many advantages to running a WB full-time. First off, a true AFR display in the vehicle will is a great tool for tuning, and monitoring to ensure consistent long-term operation. A narrow band sensor is near useless for this purpose. I'm also running a standalone that allows the closed-loop AFR target to be configured in a table. This allows running closed-loop cruise at 15.5:1, tapering down to high 12's as boost comes on. Boosted operation is set to run open-loop for safety reasons - just in case the sensor goes squirrelly.

the innovative units will throw up a warning's if they overheat. I have never seen it happen once. I am doing the same thing your planning on with an innovative and a haltech. There is a sensor cooling bung available and also instructions for making a heat shield/heat sink out of a piece of copper. I would only resort to this if you are actually getting the overheat error
