When to Re-Calibrate LC1 Wideband?

I'm noticing more swing in AFR readings, where it used to move ~.3 in either direction, now it seems to move ~1 afr whilst sustaining steady revs.
Should I re-calibrate it? I have it directly affixed to the OE O2 bung, and given their sensitivity to heat, what kind of lifespan am I looking at here?
Thanks,
-Cm

I believe it is written in the manual how often you should free-air re-calibrate it.

That's a little puzzling....

AEM says they use Bosch sensors that never need calibrating, but Innovate suses the same sensors and says that to keep the same consistent level of accuracy, you should recalibrate twice a year for a daily driver, or as John says, every time you race.

Both say the sensor is accurate to .1 AFR....

Okay, thanks guys! How many of you run bung extenders? I've been told that the sensors can't take the heat, but Innovate insists otherwise.

The aem supposedly has a self calibration I believe. But let me tell you, for user friendliness and ease of setup the uego blows the lc1 out of the water...for tuning use actually also.

The controller is the part of the lc1 that hates heat. If your bung is close to the cat location And not right in the dp it should live a pretty long life.

I would recal the lc1 every time you go to tune...I trust them that little from my experience.

Mine is in the OE location, or right next to the turbo.
