D2 traction control VS CDL being locked

[BirchHill]

To sum up my position here is a screen shot of the overview of TC from the D2 workshop manual.

The effectiveness of the traction control system in the DII is defined by the simple fact that Land Rover put the CDL back in the truck for 2004, and subsequent Land Rover models all have a form of CDL. Simply put, it was an experiment that failed.

Is traction control better than open diffs? Yes. Is it better than a locked CDL? No. Again, as evidenced by Land Rover's own decision to re-incorporate it into the vehicles. Why else would they have?

For what it's worth, I have a 2002 D2 with the CDL modification (mine needed a new transfer case housing and a shift lever). I'm considering selling it, and (if you're thinking you want CDL) that's probably worth as much as the rest of the truck. PM for more info; 120K miles and the rest of the truck is in fair shape.

In my limited experience, the CDL has made a big difference on rocky/bumpy stuff, where the TC is just flailing trying to work.

It certainly did not fail but, land rover was able to take the experiment and improve on it in future models. Hence, about all land rover model have a form of Traction control now and its quite their trademark with terrain response. Is it better with a cdl? yes and its even better with a rear locker as well.

It failed man, it definitely failed. They had Diff lock in every year of the Disco 1 without TC, then they put TC in removed CDL and had to reverse that decision.

 

[BirchHill]

so its a failure yet they now use it in about every vehicle they make? okay that makes sense.

I had an 04 D2 with a cdl. I can tell you from many hours of off road experience in that truck a cdl makes all the difference. On high mountain passes with tight switchback, unlocked using only the TC worked great. In deep mud or twisties I always had to lock the CDL to make it without blasting through it. Anyone who says a cdl isn't necessary has no clue. If that was the case, why did LR bring it back for the 04 models? It was because the TC by its lonesome wasn't cutting it.

Land rover brought back the CDL because of consumer demand. And in 90% of situations it is not necessary and certainly not in twisties. Deep mud it would be an asset

If you don't think it's necessary you must not be traveling off any gravel forest roads. If you get in anything off camber or sloppy it makes all the difference. I can guarantee everyone who has posted in response has more experience with Rovers and the use of the CDL on them than you do. You have no argument, just end it

He said unlocked in twisties, locked for any real obstacle. I'm not sure why you're so opposed to the unreal benefit of CDL. They didn't bring it back because of consumer demand, they probably got rid of it because most consumers were too clueless how to use it, and they saw it as an unnecessary feature for the grocery getter audience. They brought it back because the most capable luxury SUV was no longer the most capable, it needed the CDL. That's why they kept it in the future models, as well as making TC a million times better(if you haven't driven a HD package LR4, do so, the TC is not even close to comparing)

land rover has stated that they brought back the cdl due to consumer demand for it, sorry its a fact. To be back on topic I have never said TC is better then a CDL, only that in most circumstances encountered in overlanding the TC can spin its way through, its not pretty but it gets through. It appears based on several of the comments on the conditions you encounter that you all are more into visiting the local mud park. In that case you should add a cdl, rear lockers and a set of super swampers because your right, TC is not going to cut it.

No, I absolutely hate mud. I just like to travel on trails that are tougher than Camry rated.

Wow, so a TC only equipped disco is no more capable then a camry? Toyota are good just did know they were that good.

 

[Howski]

Did I say that? Absolutely not. I just like to travel on tougher trails than graded FS roads (the 'Camry rated' trails I was referring to). CDL is very helpful on these trails especially when it's wet out. I believe we have very different opinions on what 'overlanding' is

The failed experiment was removing the CDL, not adding traction control! This argument is a joke.
