Thanks for the kind words, folks. Glad it was helpful.
To answer your question, Quicksilver, I have seen no such relationship. I don't usually pay RPMs much mind in an automatic except in a general way. It's on my list of things to check out, but I don't expect to find anything useful in terms of economy, though.
Scott, I agree completely about the load. It's pretty clear with a ScanGuage. That said, since load and acceleeration are also closely related, it's still high on my todo list to do some testing to derive some principals about under what circumstances to accelerate how hard in order to mminimize gas consumption. I'll have to get back to you about that.
As I said, I've been focusing on MPG, which is kind of the simple answer, and I think it's time to start looking also at GPH. I'm not sure what kind of relationships to expect here. Time to do some algebra, maybe. I'm wondering, for example, in what circumstances, if any, you're better off shooting for low GPH, vs. low MPG -- or if just going to max MPG is sufficient. I just want to understand that whole thing better.
