wideband O2 sensor location on downpipe

Ok, here is a dummy question. If you look straight into the engine, and where the DP is located, 12 o'clock is top dead center, would placing the sensor @ 8 o'clock be an issue with most aftermarket wideband? The reason I am asking is, I am getting the innovative LC-1, and my DP already has a bung weld on by my tuner, any recommendation? If I can keep my current bung location and use it for the wideband.
Thanks

My understanding is you do not want to place it in a position where moisture can build up.
This may work fine, but cut the longetivity of the sensor. Just as important is the distance from the turbos, I think it should be at least 18".

Two things to consider:

The sensor should NOT be in an 8 o'clock position because condensation would gather in the bung and after start up the condensation would turn to steam, which would kill the o2 sensor quickly. You want to have a position, probably between 10 and 2 o'clock.

As far as distance from the turbo, my AEM recommends a minimum of 36 inches from the turbo manifold. They are very clear that if you place the o2 sensor closer to the turbos, the lifetime of the sensor would be drastically shortened. I think that the LC-1 uses the same Bosh sensor as the AEM so, it should apply. I placed my sensor into the midpipe and before, I actually cut the shiedling off the stock cat converter and put the sensor just before the converter so that I could get my 36" distance.

Ideally you want 12 o'clock, but absolutely no less than 3 or 9. Mine's mounted just past the bend after the downpipe on the midpipe.
