I hadn't realized that such gadgets existed until you mentioned it. I found a couple with an "Eco" mode that is a step closer to what I'm looking for, but nothing that gets all the way there.

Most of my driving is between 700 and 1900 RPM. In that range, I want the torque to be linear to accelerator pedal position. This is tricky because the relationship between accelerator pedal position and throttle blade position is a function of engine RPM. At low RPM, you get 90% torque with the throttle open less than 20%, while at high RPM the throttle might need to open over 80% to get 90% torque.

Maybe it's time for me to learn how to work with an Arduino....
