Can factory cruise control be adjusted to be less aggressive?

My cruise works great at 70mph,
but when I use it at 40-55mph it constantly floors-it too often.

On other cruises, I have seen switches that you can use to calm-it-down a little.

Q: Can I do that somehow on my car?

I took the unit apart and all I see is a 4pin connector. No way to open anything on the cruise-unit apart to look for switches.

Q: Is there a circuit-board somewhere else that might have some adjustments on it? If so, where is it located?

I am not much of a mechanic, so very detailed location information appreciated!

Thanks Guys! Thanks for this service.

Hi Jim,

Thank you for the donation.

There are no adjustment that you can make on the cruise controls and I have something here that might helps.

OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET

If operator repeatedly presses and releases SET switch with their foot off accelerator to begin speed control operation, vehicle may accelerate and exceed desired set speed, then decelerate to less than desired set speed, before achieving desired set speed.

Speed control has as adaptive strategy that compensates for variations in speed control servo cable lengths. When speed control servo is set with vehicle operator's foot off accelerator pedal, speed control servo compensates for excessive speed control cable slack. If lift foot sets are continually used, speed control overshoot/undershoot condition will develop.

To "unlearn" overshoot/undershoot condition, operator must press and release SET switch while maintaining desired speed with accelerator pedal, then turn speed control switch off after waiting 10 seconds. This procedure must be repeated 10-15 times to completely unlearn overshoot/undershoot condition.
