Bypassing Traction Control

Sorry but TC does not work like that something else is going on. TC does not stop a wheel just because it is spinning - it brakes a wheel that is turning faster than its sibling so if all 4 wheels are spinning at about the same speed - TC will not kick in.

As mentioned - does your vehicle have Stability Control as most other newer landies have? If so this is normally the culprit and needs to be turned off when on slow offroad. If no Stability Control then comments early in the tread apply.

But if all 4 wheels are spinning, unless they are spinning at greatly differing speeds then TC will not kick in.

I've seen people hit the bottom of Big Red at 80kph and dig themselves in with wheels spinning madly before cresting the top. Last time I was at Big Red I watched a few doing this before I walked the Td5 Defender up in 3rd gear low range with very little wheel spin at all. One of the guys in our group stopped part way up then restarted and also walked over the top. A comment from some onlookers at the time was "Is there anything these Land Rovers can't do?"

I did Big Red last year with no issues first attempt, hardly noticed the TC light come on at all, I got to the top and my mate in a Patrool was impressed. My TC only comes on when I fail to lock in the center diff.
I thought Big Reg would be big, bit of a letdown after watching the Dakar and seeing the dunes in South America.

Big Red has had about 20m removed/flattened from the top between 1983 and 2003. When I crossed in 1983 it had an almost knife edge crest whereas in 2003 and also now you could park 100 vehicles up there. :o A mere shadow of it's former challenging self.

There are other ridges in the Simpson that are higher than Big Red and IMHO more deserving of the name.

25m climb?
It may be 2 Km long, but you really have no idea of what you are talking about. the last section is where all the angle is. It's not like it seems from your computer chair.
If you are game, you can come over and do the hill one summer. I'll even take you there, and, show you how it can be done and made to look easy.
And, you could always escape from Bornholme Beach via the old track while you are here. I do it. Lets see how you go.

Making judgement calls from your computer chair isn't to bright. Nor very well mannered.

You seem to have taken my statement out of context.
Perhaps you could re read it, in it's entirity.

If you don't understand what I have said, feel free to ask for clarity. I will happily use different words to try to clear up any miss understanding.

And no, I don't have stability control. Thankfully.

If you're spinning wheels you might be using too much throttle. I find getting momentum up before hitting the sand and then easing off the throttle makes it easier for the tyres to grip and so reduces wheelspin.

Just to put the place on the map
See attached
200m climb over 2200m

Interestingly the same 1:10 gradient as the sand hill off 14mile beach at Cape Flattery - but callcup is twice as long
Ouch!

I still think a rear ATB will be your hero

Seconds out . Round 2

Sorry - I read your post in its entirety before responding - if you meant to say something else then you need to explain further - I stand by my comments.

My sons had the TC disabled due to a fault with a wheel sensor on Fraser Island a while back,and the vehicle was nowhere near as capable as it was while it was working.

Thanks for this Scarry.
But now I have some questions. :)

Are you talking about just when he is sand driving? Because that is the only time I would turn mine off.

Just so you understand where I am coming from;
For everything else I was intending on leaving the TC on. In fact, I was intending to leave it on for most sand work too. But, for those chopped up challenges that nobody seems to be able to get up, I thought it might be better turned off. And rather than pull the fuse, I thought it would be better to fit a switch.
Plus, I can always remove the switch if it proves to cause more problems than it's worth.


Though, now that I have seen the data on the Ashcroft ATB.... I think I want 2. :-) And for the price, it would be probably worth it.
