Greg,
You are definitely one of the most knowledgeable guys here on fuel injections.
To answer your question: YES, it is very easy for us to set the kit to use one O2 sensor. It is simply calibration changes. The only problem: you will have to get a 2-in-1 exhaust pipe first.
The primary reason to use 2 O2 sensor is because the stock engine has 2 exhaust pipes. One O2 sensor can not handle that. Certainly 2 O2 sensors give more accurate fuel controls on indivadual cylinders as a plus.
In the automotive world, it is called "2 bank" system, if you look at those V6 engine, V8, V10, V12, engines, they all have at least 2 O2 sensors on the 2 banks exhaust manifolds, of course at the joint of "x-into-1" locations. Actually they all have more than 3 or 4 O2 sensors before and after the catalyst(s). It is regulatory requirements to do that, otherwise all those OEMs would fail the emissions and OBD regulations. Remember, we are in Detroit, we come from automotive industries.
The reason most motorsports people don't do 2-bank system is because 1) it's very complicated; 2) it costs more. They would rather to ask you to change your exhaust pipe.
It's our mission to make this kit a PNP, and costing the least for customers. We are good at ECU technologies. We can do that, yet with a reasonable cost.
