Cruise Control Question

Anyone know of a way to re-program the cruise control so that it can be set
and/or operated at below 25 MPH?

I don't think you'd want to. I've observed this with other types of
cruise controls and I have no reason to expect that a Saturn CC would
be any different. At low speed, the cruise control is erratic and
doesn't regulate well. With a slight drop in speed, the throttle is
pushed open too far and the engine roars to speed up. Then as the car
over-speeds, the throttle is slammed shut and the car lurches as it
slows down to below the set point. Lurching between fast and slow, the
car never settles to a steady speed. It's like those TV comedy
parodies you see of student drivers trying to learn to drive. That's
why there's a lockout. Even slightly above the disable speed where the
system can engage, the cruise control doesn't work as smoothly as it
does at highway speed. It's worse when driving over irregular terrain
where it has to compensate for hills. Add the hazards of automated
driving in town where you should be paying closer attention to things
like parked cars and kids running out into traffic and it's easy to
see why they set an engagement lockout for low speed.

I observed this on an old Cadillac with an old-fashioned pneumatic
servo cruise control when the lockout speed was set too low. I also
saw it on an aftermarket Dana system while adjusting the trimmer that
sets the minimum speed. Cruise control just doesn't work well slow.

Until someone invents a smarter cruise control that can look down the
road and anticipate, like a human driver does, I'm afraid that's the
way things will be.

You think wrong. Trust me. I want to. <evil, but friendly grin attached
here>

I should have mentioned that I have a stick so regulating the RPM's VS speed
is no problem. Cruise works just fine at 26 MPH in 4th gear most of the
time (sans hills) and 5th anytime above 30 without those same hills.

If I could get it to set below 25, I'd be using 3rd or maybe even 2nd... I
can see how an automatic would have problems with this, but with a stick,
*I* choose the RPM range to be stuck in while under cruise control.
