BTW, great to see you around, Peakster

Have you investigated a constant throttle version of CC? I haven't done any extensive testing on it, but I rigged-up my cruise to govern the throttle to about a 21 TPS.

-If I set the cruise for 65, it will hold the speed at 60-65 without a problem and reduces the throttle if the target speed has been exceeded.
-When a hill approaches, speed starts scrubbing-off as load builds. If winds and the hill are neither too extreme, then the lowest speed results in 50-55 mph. -Then after the crest of the hill, speed builds again.

It's a great "set it and forget it" feature for long highway trips, reducing fatigue. Of course, I need to test it more thoroughly -- i just have tank data to support some incremental improvement.

Usually, how long are your tests (distance-wise)?
