Cruise control might be better on flat terrain

[Bill in Houston]

The cruise in my CR-V seems to downshift quite aggressively. I think I will do the hills myself, and relegate the cruise to flatlands. Thanks for posting.

If you have a Scangauge II and have "horsepower" programmed into it, you will notice that while on cruise control that the horsepower will go up and down at regular intervals. In a way, cruise control is doing a very minor pulse and glide to maintain speed. This may be why cruise control can be best on long flat stretches vice trying to keep that right foot at a steady throttle/speed.

Since getting the GasDwarf, I've been using CC a lot.
Even down into 20mph zones.
When I briefly tested it, CC seemed to give really good results, compared to manual (footual ?) control.
So I just resorted to the habit of getting up to my chosen speed, and hit CC ...

But I've recently been triggered to NOT use the cruise control , as a test.

Guess what : FC was way lower all across the board !

I've matched my previous FC record.
But that was a record that was likely only due to the CNG station not giving its normal pressure ... (compressor was already running when I arrived there)

I've been seeing extra-ordinary values on the build-in computer - like 10% lower than usual.

I seem to have been driving a tad slower though - which is partly due to the car losing some speed when you ease off the gas .
The smallest change in throttle, results in a speed change ... with a lot of lag.



Oh : The land around here is pretty much flat .

im building currently my own electrical cruise control with a stepper motor and a controller. I was first thinking that i will make it constant speed control, but in second thought, i thought that constant throttle is better, just because the normal cc is constantly accelerating and decelerating, whick is bad for FE.
I will post it on the DIY section once it is built
