Autron Cruise In GU III Patrol - What's Normal?

Hi all,

I had an Autron Cruise Control fitted to my GU III/manual/3.0 Patrol and I am not happy with its operation.

Having had cruise in two of my BA Falcons (drive by wire) the Autron unit is SLOW to react to changing conditions, ie when going up a steep hill, it drops 10-15 kph before it kicks in and picks up the speed, then after you crest the top it will accelerate down the other side by about 10-15 kph before backing off the throttle.
In normal running the speed fluctuatates +/- 5kph at 80-90 kph.

The other thing I don't like is the operation of the steering wheel mounted control. I have a section of road I travel where I press the accelerate button on the steering wheel control and it takes better than 12 seconds to accelerate from 60 to 80 kph, and this is downhill! Using the accelerator it takes about 7 seconds.

I have returned the vehicle to the only authorised dealer in Southern Tasmania and the first time they changed the internal settings to the fastest possible, took it for a test drive on the highway at 100 kph and it performed flawlessly, but on secondary roads between 60 and 90 kph it's terrible.

I have had the vehicle back a total of 3 times and they assure me it is getting full throttle when needed and intimated I am being podantic and saying there were no more settings to adjust.

What have been your experiences and what's my best course of action from here?

Cheers,

Peter
