Have you tried Sport mode on the transmission?

						SubscriberMy cruise control seems to be set to nanny mode - that is, it is slow to respond to hills, and only slowly gets back up to speed. Presumably this is done for economy reasons.
Is it possible to set the cruise control to hoon mode via the OBD2 port? I don't mind paying for the extra fuel.
Thanks, Paul

Interestingly, I don't use Cruise Control when there are hills about but I leave it connected for the odd hill on a drive through 'normal' terrain.
However, I find that if I am set on 100Kph on Cruise and get to a hill, mine maintains the 100Kph for the entirety of the hill - just keeps kicking down gears and revs up to maintain the speed. My D3 hoons
I just feel that is exactly what it feels like - hooning. To be on 100Kph back in 4th (maybe 3rd?) gear with 3,500+RPM doesn't feel, or sound like 'good travelling' for a diesel.
It is OK when coming up on a hill and the auto kicks back from 6th to 5th and gives itself a bit of tickle rev-wise and then drops back on the other side. Feels very competent and the only sensation is a slight change in engine rev noise. Usually not even a 'push in the back'.
I just hate the sound of a high-reving diesel, I guess.

						SubscriberI would have thought the cruise wouldnt be any worse than the older models.
You could try a gearbox adaptive reset (with a diagnostic tool) and see if as the gearbox relearns it makes a difference. Another suggestion is to keep it in sport for a week and drive it like you stole it - the gearbox will relearn and that may make a difference.
Mine has the annoying habit, on long, minor freeway hills, of dropping to 5th for 10secs til it gets back up to speed, then changing up for 10 til it looses speed, then dropping to 5th and so on and so forth!
Cheers

						SubscriberOn my 3.0 D4, I have to press the cruise + button when the hill starts, then press the cruise - just at the top to maintain any set speed, as the cruise seems to allow a +/- 2 km/h difference in speed. Quite frustrating compared the the cruise on my '03 Saab 9-5, as it will react much faster than the D4 to terrain, maintaining a speed up a hill without excessive throttle, and cuts the throttle as soon as speed exceeds the set cruise speed - whereas the D4 seems to keep fuel on down a hill.

I notice a large difference when towing. The cruise will happily drop 5-8km with the van on the back without racing back down through the box, but I think is more sensitive without it on.
I actually really like it. I'm rarely in a rush when towing so happy to speed up/down with the hills.
This is with a 3ltr 8-speed.
In the old days when a cruise control was a seperate module you could just wind the gain up with a screwdriver on most units. Modern cars have similar setttings, but in the software.
My last company car - a Captiva - had a similar issue - the speed would droop over 10KPH up hills, which Holden fiddled with on its first service and fixed. Not knowing how the LR systems work, I'm not sure if you could do it with a domestic diagnostic tool, but LR themselves may be able to (although they could be unwilling too)
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.
The IID tool has some cruise control settings in the BCM ecu which can be changed but I think it relates more to how cruise control setting display on the instrument cluster and what type of cruise control is filled -none, standard or active etc.
There is another setting know as 'JAG Cruise Control' with various options. I don't know what they do but I don't think it relates to changing characteristics like 'dead band' etc. of the currently fitted cruise control which you seem to be interested in.
You could try contacting GAP for further explanation plus they seem to be very response to suggestions re. investigating and adding additional functionality if it is possible.
