I am talking about the scanguage reading. With the throttle out, mine is at 10tps. Floored it is at 90tps. So 80% would be 74tps. I do not understand the entire concept of engine load, i have tried doing research and this whole DWL thing just doesnt make sense, there is no good article out there explaining the physics behind it, and how to implement this hypermiling technique.
I did the test today, and came up with 1.28GPH average in third gear, and 1.14GPH average in fourth gear. This comepletely defies common logic, but you cannot argue with a scientific instrument, so i guess i will be launching from second, and driving in fifth at 30MPH now. It does make sense in the fact that you have less torque, so you arent wasting gas on quick accelleration, but i thought the less torque was due to inefficiencies in a higher gear at low speed, not a compensation for power/energy.
