Wouldn't you want to testing drag and downforce at the same time if your goal is FE. One can certainly create downforce at the cost of drag.

I thought of electronic throttle control (and diesel engine management, often with no throttle) when I was developing the idea. In both cases, the accelerator pedal position determines, for a given rpm, the torque output. So, no problem.
There is no need to test for downforce at the same time: either lift or downforce will cause induced drag, and so measuring drag already includes it.
Of course, you can choose to measure lift/downforce alone if you wish to, and that can be done quite accurately and fairly easily on the road.
