Contour Enthusiasts Group Archives Forums Modifications Forced Induction Wideband location

Where is the best place to put the O2 sensor for the wideband in our turbo setups? My current one is way downstream of the turbo, right before the cat. Is that the best place? If not, where would be better?

As close to the exhaust turbine, in the downpipe, without obstructing flow. At least that's what I think I remember reading.

In terms of exhaust flow direction:

After the turbine before it enters any catalytic converter.

On top of the pipe if it is horizontal to the level of the road so moisture doesn't fall on the sensor.

NOT before the turbo because of high exhaust pressure and temps that will burn the sensor out early.

All this is listed in the information that came with my wideband bTW.
