First,
THANK YOU, Mitosis.
This was more than I dared ask for. It is truly useful. And interesting, too.
It's all very nice to speculate, but I'll take hard data over opinion and speculation any day. Data is vastly more useful than the unsupported opinions of strangers.
Your graphs support my decision to set my "oil temperature timer" to 10 minutes; when that time elapses and it beeps, I believe it's safe to begin driving my car harder, employing progressively higher revs and more throttle. (It's a credit-card-sized $6 timer from Walmart.)
It's interesting to examine your graphs. I note that the coolant temperature typically begins far higher than ambient temperature. I assume that's not residual heat remaining from the previous drive, so I'm guessing it's because the engine has been on and idling before you drive off. The graphs seem to begin when you drive off, not(?) when you first start the engine.
Do I guess correctly that you live within about 2 minutes drive of the Interstate?
On these graphs, you're accelerating briskly up to 75 mph within less than 3 minutes from first driving off. I wonder if the time to bring the oil to proper operating temperature would be extended were one to spend the first 10-15 minutes just gently driving around town at no more than, say, 40 mph? My guess is that it would not take significantly longer to bring the oil up to temp. But, I don't know.
Perhaps you'd care to log that and share that, too. (It is interesting what you can do with that tool.)
As you noted, the Engine Load % is interesting. I wonder what parameters they're measuring? Do you suppose the software may regard very low rpm + large throttle opening as lugging and show that as high load percent? Just guessing, trying to account for what you've seen as odd graph lines for that measure.
It is generous of you to share the fruits of your labor so that others may benefit from your purchase and from your work with your fascinating new tools.
Again, thank you for sharing this, Mitosis.
Finally, is there anything I might do for you in return for your kindness? Anything about our wonderful cars or about driving, perhaps, that I could share with you? Any questions at all about, oh, handbrake starts on hills, or heel-and-toe, etc? (I don't know your age or experience. Me? I'm old and may have learned a useful thing or two over the years.
