Sorry for the mis-information. In hindsight of course uS would have to recognize that pin, since its in the schematic...doh. Often best to not answer questions, if one is not 100% up to speed...

It can certainly help on engines that have different cylinder characteristics, but if it is a symmetric engine with a throttle body I wouldn't expect much need for 2 sensors. However, you can find out by measuring EGO on each exhaust bank and seeing if there is a difference. But us the same sensor on each side so you don't see a difference that is due to the sensors.
