I knew that O2 on a "regular" car would be the problem to overcome so I pointed out that my car had the standalone ECU but let me address it again in more detail:

Since my car has a stand alone ECU where I can control every aspect, all problems concerning O2 sensors are eliminated. In fact, I tuned the car a year ago and have not even had an O2 sensor installed in it since that time. I tell the car how much fuel to dump in, it doesn't decide on its own how much to dump. If I am running with an OK mixture on 4 cylinders (as read by a WBO2 sensor) then killing fuel to 2 cylinders will still give me the correct mixture in the other two.

So, what else do I need to consider for this test? Comments/suggestions?
