I have ACE on my disco but would like to run with a completely disconnected anti roll bar off road. However, when I am on-road I would like to have the ACE.

I plan to have a mechanical disconnect but I feel it would be less than ideal having the ACE system still running and actuating without being connected to the axle.

Would I need to have a NANOCOM to enable/disable the ACE when transitioning from onroad to offroad? Or could I just switch power from the ACE pump?
 
Surely ACE should give you loads of flex off road. Are you 100% sure it is ACE limiting flex? Have you tested this on a high lift?

IMO first of all you should study how the ACE works and how it was built to realise that it's better off-road than those with conventional ARBs as it gves you more flexibility especially that it's completely releasing the bars at very low speeds unless it goes to the "slide slope detection" mode based on the accelerometer's inputs and locks the bars to increase stability and vehicle response on a side slope

switching off it's power sends the system to "locked bars" default when it acts like a non ACE vehicle which has less roll capability ... learn to drive it off road as it is cos it's a very well engineered system, any interference in it's operation mode can only make it worst, believe me or not

I though the whole point of ACE was to give you good on road handling and good axle travel off road?

It is. It is a very good system and a shame it wasn't used on other vehicles like the p38 Range Rover or Defender. Although it was used in the RRS L320 under a different name and still exists on newer full size models today.

Without knowing what the op is doing or their setup, it could be a limiting factor, but I don't have first hand experience. But they would likely need to be doing something rather extreme, rather than just a 2" HD lift kit.....

It was one thing I really missed when I bought my D3, which did and still does handle like an over loaded whale!

They are fine connected, you do not need to disconnect, as that is sort of what ACE does, but hydraulically.

Indeed, the D3 is quite nice, but somewhat of a barge in the corners. The Range Rover Sport on the same platform came standard with the next Gen ACE system on the V8 models (diesel & petrol), but was optional on the V6 diesel. And never offered on the D3 or D4. I'm sure some boffin could get it to fit and work, being the platforms are the same. But I wouldn't have a clue on where to start.

Guy up Scotland used a rrs chassis to make a 3.6 v8 d3 with ACE, was on the d3forum, guys name was/is discomikey.
 
IN my experience the D2 with ACE is not nearly as compliant as a Defender without ARBs. I also plan to increase the amount of droop over what I have and can see the ACE ARBs becoming even more of a hinderance.

IMO if you want to transform a well enhanced D2 into a Defender better sell it and buy a Defender ... no offence

What do you mean by compliance and how is ACE impacting this? Curious to see what mods you are proposing for more droop. My guess is ACE isn't currently the limiting factor.

With anti roll bars the more travel suspension you have the more ARBs become a limiting factor as you are attempting to flex the axles further in respect to the chassis (precisely what ARBs attempt to counter).

I plan to add 125mm additional travel dampers along with dislocation cones. Without a similar increase in ARB compliance I won't be able to maximally benefit from the additional available travel.

This is just my thoughts of course and I have little experience of the disco2 and ACE. I will add the longer travel first and assess the behaviour of the ACE ARB. It may surprise me.....but I am a bit doubtful it will be ok with such an increase in travel.
