The old O2 sensor is too far away from the engine excuse, is just that, old. Back in the days when no one had access to tune a factory OEM ECU it was true that it would cause problems. That can be corrected in the tune of a Ford ECU today, especially now that the O2 are heated. I am very skeptical that this is going to fix anything.
Also I am very skeptical that these so called self tuning systems ever come close to the same performance level as tuning it right.
