Can i run 2 02s to ecu and have it divide the value by half?

 

No. If running dual exhaust just use one sensor, it'll work.

Just run one sensor in the y where they meet up Rbob? or just run one in the stock location?

 

Either way. Note that GM put the NB O2 in the drivers side exhaust on many vehicles. Which is only measuring that side. The V8 f-body's are this way. There is even a set of long tubes headers made, can't recall the manufacturer, with it in one pipe of the drivers side.

It wasn't that far down either, the stock wiring reached it.

In the 2.8l & 3.1l MPFI f-body's GM placed the O2 sensor down under the car in the Y pipe. Adjacent to where the crossover comes in. This is all well and good until cold wet rainy weather. Which then has water spraying onto the sensor cooling it off and the BLMs start to go up and the mileage drops like a rock...

so stock location has your satisfaction. check.
