Wideband Placement Question

[BongRips]

The narrowband placement is pretty damn close to that isn't it? And are you happy with the results of you placement? I was thinking about doing the same thing and grabbing a UEGO as well cuz they are good for $200

My AEM UEGO is in my decat and when im on the dyno we use a second bung at the end of the downpipe for the dyno's wideband. The readings are almost identical.

Result's of testing that I have seen result's in different A/F ratio's throughout exhaust.

From what I understand, dumppipe / downpipe is best for a fast reaction time (tuning transient fueling), but sensor can fail faster.

Further down exhaust is for less turbulance (caused by turbo exhaust wheel) for supposedly an accurate measurement and for longevity of sensor, but response time is slower.
