I second this, whilst in the perfect world, with the correct tyre pressures, TC and CDL is flawless, the reality CAN very occasionally be somewhat different. D2's don't habe CTIS, so to say "your tyre pressures are wrong, that's why TC set your brakes on fire and got you bogged", can be a flawed argument, conditions change... I know I sometimes prefer driving on sand without it, but I learnt without it ;)Quote:

^^^^^^^^ what he said , long uneven sand hill with a D2, much better without tc , plenty of sand in sandgroper land, by the time the brake has been applied to spinning wheel the car has already moved another few metres to where that wheel could have had traction, if the brake wasn't applied in the meantime sapping power to maintain required momentum, in other situations tc works well,Quote:

In the later D2a the SLABS was re-programmed to work with CDL.
Myself, Offtrack and others have fitted the later re-programmed SLABS unit to our pre-facelift D2's, for around $100 and an hour or so time it's a good modification. It has certainly improved the 'drivability' off road and IMHO you will find that the TC will not be working against you. I have spent a considerable amount of time driving in the sand on Teerwah Beach just south of Fraser Island and I would certainly rather have TC than not.
As Twr7cx has said, the best set up is with helical gear LSD diffs (Ashcroft ATB for example).

great bit of info
I mainly drive on sand in a CDL upgraded 2001 D2 and like the idea of CDL & moderate TC
Is there a discussion on how to do this swap somewhere or even better a photo tutorial. I am wondering how hard it is?
will any D2a Slabs ECU do the trick ? need anything else?
Anyone got a suitable SLAB's unit !
cheers

Nobby, this thread started by OffTrack covers the change over to the later SLABS ECU.

Ebay, a wrecker or the AULRO Markets will source you a unit. I, like OffTrack, sourced one from the US. I was in a hurry and couldn't find one in Oz at the time.
I paid $100 + shipping. You will need a Nanocom to load up your settings, easy to do.

Towing in sand is certainly assisted by combination of both. I could have left mine selectable on off etc but after testing decided it was better on all the time. As i say even peops with a lot of sand driving will have differing views on this. I recall an extensive test in a major mag a few years ago and it too concluded that when comparing the same vehicles ETC on all 4 wheels in sand was better than open diffs only including dune climbing. I dont rely on that but rather my experience. I have towed well over 2 tonn in deep sand and etc with the v8 grunt was a very good thing.

As you say Ozscott, it's a very subjective matter, I, like you, prefer TC on all the time, especially with the updated SLABS ECU.
IMHO I wouldn't change it. The point I was making was that the instances where I would turn TC off were extremely limited, basically only in certain circumstances in sand, and as other have said, just adjusting tyre pressure could also be a fix. In all other situations, dirt, rock etc i reckon the early TC with CDL is far superior to a D2a. Think of it this way, if your in a situation where you think Tc is inhibiting you, you have a couple of options available to overcome it. Alternatively, if you change the ECU, you lose all of the benefits, for a gain in a very limited set of circumstances.Quote:

The later model SLABS ECU's are available from the USA for cheap. You can upgrade to the newer revised TC settings that way.Quote:

towing well over 2 tonne , deep sand = deep s%*# ,
I know this from retreiving tourists from the local beach who thought that having an off road caravan / heavy camper trailer meant that they could go through deep soft hot sand
