Having played with several O2 sensor locations and various sensor bypasses, I would have to say that changing the location of the sensor to closer to the exhaust manifold won't result in a noticeable change in fuel usage. I have a 1988 745 that I de-turboed using an engine from an 86 240. The car gets exactly the same mileage whether the O2 sensor is close to the Cat or the manifold.
