It is nice how the same tool can serve different people in many different ways. |
2 or 3% difference in TPS, which you won't notice at all if you couldn't see it, might be 7 to 10 mpg different. Maximizing the overall average mpg is all about getting the best mpg for the longest amounts of distance. When you know what TPS reading is needed to run at what speed, you just accelerate (I use 21 TPS usually) up to the desired speed and then back off to the correct TPS to maintain it.
BTW, on a small car in gallons, GPH doesn't say much because 1/10th gph is a lot of fuel. That's why I use TPS instead. With something that only gets 21 mpg and measuring in litres, I'm sure you have huge numbers to look at, and therefore they move a lot as you press on the gas or not. My GPH never gets over 2.0, so its very difficult to notice small changes while driving because its not accurate enough.
Waste not, want not.
