First Gen weber tuning
I've been thinking it would be a lot easier to fine tune my Weber 45DCOE if I broke down and put in a couple of O2 sensor bungs for an Air/Fuel gauge.
However, I have the racing beat street port exhaust ( RX7 1975-1985: Exhaust - Complete Systems: Street Port Exhaust System - 79-85 12A - ) and the two pipes don't converge until a few inches before the muffler.
So which pipe do I weld in the O2 bung? And how far back? (I'd rather not drill into the stainless steel header)
I would think you'd want one in each, since a weber seems to tune one barrel for each rotor, but then how do I wire the two O2 sensors into one air fuel gauge?

I just wanted an air fuel gauge as a secondary tool, I'm planning on supercharging in the future, and then it's going to be even trickier to tune.
