That looks like a pretty nifty datalogger. I have to wonder if the mpg versus time plot is intentionally dumbed down. The real picture would have the mpg hit infinity every time you DFCO, and then slam back down to zero when you come to a stop. What if this is some sort of moving average?
In any case, a plot of gpm versus distance would be the easiest thing to look at and make good sense of. Area under that curve is obviously fuel consumption.
As always, I would love to see a breakdown of aero, rolling, braking, and accessory load.
Somewhat off topic, how hard are you accelerating when your catalyst temperature shoots up to 3000°C? Does this represent a leaner fuel/air mixture than you'd see in a high-speed hill climb?
3000°C! That's higher than the glass point of glass or the melting point of steel. That seems unsustainably hot. It makes me think I should be careful about adding insulation to my cat. Fiberglass batt would be too much; I'll just wrap it in a few layers of aluminium foil to replace the rattling heat shield.
