No, not a red herring at all.

But you kinda did release "data", so can you help me understand what controls were used? The reason I ask is because presumably the FVT xprize team did tune for a specific rpm in a series hybrid, and despite having an engine running a generator and charging/discharging a battery, and finally running an electric motor, they were showing good numbers. And they didn't use HHO. So it is possible you managed to recreate peak bsfc tuning as well (which would fall off sharply) and the hho was a red herring.
Without the small amount of HHO, the mixture would not ignite reliably.

I do agree the spark plug pressure sensor seems expensive for what it is in components. It might be worth something to the forum community to have such a sensor for engine tuning. As such, I'll look into fabrication of one unit before I break down and purchase a commercial unit. All we really need is a pressure trace in comparison to crank position to allow us to see any and all effects. I understand there are several techniques for noise cancellation. It's just a matter of looking into it.
