Newer engines are electronically controlled, usually by a computer - hence, no throttle cable (at least in the historic sense). The current "gas pedal" actually works an electronic actuator that tells the computer what your foot is telling it.

doesnt matter you can still put a cable or a 2x4 to hold the throttle in one place and get the benefits

So what you are saying is that the cable will let you set the RPM you want to drive at. Correct?? Then when I set my CC at 1800 what is the difference? Dont flame I want to learn!

I never said 23, my best loaded over 600 miles was 21.3; My best empty at avg speed of 44mph was 30.2

Just tell me what the difference is between having the Cruise Cont. holding the RPM at 1800 or having a cable hold it at 1800 RPM.

WRONG, RPM will not be held constant or speed, terrain will decide your speed and RPM. Fuel will be held constant

ok I think I got it it must get frustrating driving like that at times ? And since I have a 2003 and I have fly by wire I can not have a cable right?

With electronic fueling, you can just put a potentiometer in circuit in place of the throttle with a switch.
If there is also a switch on the pedal, you'd have to bypass that too.

The big difference is with cruise control when you come to a hill it'll add throttle to try to maintain a constant speed, probably also causing you to downshift if youre driving an automatic. The cable holds a constant throttle setting and will most likely keep you in the same gear, unless you slow down too much going up the hill.

Until recently, ALL vehicles had a throttle cable. My 2006 Taurus does. It is a cable that goes from the throttle body to the gas/fuel pedal.
Many diesels have a knob that sets a high idle using a cable. But on the buses, and big truck. It automatically disengages, once you start to move.
My 2004 150 has drive by wire. Has no throttle cable. I hate drive by wire. With a cable. When you set the cruise the pedal goes down to where the speed is set. With drive by wire. The pedal stays up. You can't find where it is, when you want to help it. Also it tries to anticipate what you want to do. With a cable. It simply opens the throttle in responses to how had you push the pedal. I ike that much better.

I never used my hand throttle on the highway, only off road at very slow speeds. I have no idea what the highway mileage effect might be.
JPonder seems to have quite a bit of experience with the highway aspect of hand throttles.
