Thread: ACE with sway bar disconnect

I believe the ACE system will generate a lot of faults if you try this. The ECU won’t be able to reconcile what is happening.

ACE does go into limp mode when in low range at low speed so not sure how much extra articulation you would get with this.

Have you tried disconnecting and seeing what happens in low range and low speed?

ACE should effectively disconnect the sway bars in low range

You will have to deactivate the ACE to do this otherwise the rams will still operate and then you'll never get the links reconnected.

The above point by Discorevy is a good one though, the ACE when offroad releases when the conditions are met and works like a swaybar disconnect. The ram will allow you to run like a disconnect with up to about 9.5" travel approx, so unless you're running a lot of lift and travel then you're probably not going to gain anything out of running disconnects on an ACE vehicle, and almost definately nothing to be gained with a 2" lift.

That said, if you do, I understand there are Jeep disconnects that will work.

ACE unlocks at very slow speeds (under 3.5 kph IIRC) and only appears to be associated with low range because it is difficult to travel slow enough in high range. I built a speed signal generator to supply the ACE ecu with 3 different speed signals: 2 kph to keep the bars unlocked at any speed, 35 kph maximum to allow ACE's rough road softening of the bars above the normal 40 kph limit or the actual speed.

I like that.
Clever.

I've been tinkering with the idea of installing ACE bars and rams with a kinetic style shuttle valve assembly on my non-Ace car so I can have compliant suspension on dirt and typical Australian secondary roads as well as off road

I disliked the rigidity of the ride of my 2nd D2 with ACE after having removed a drop link from the front bar of my 1st D2 (no ACE) so with the signal modifier fitted I normally drove with the max 35 kph setting to mostly smooth-out the roughness of the sealed roads around here - only mostly because ACE has to detect roughness to relax the bars yet once relaxed, the road becomes smooth again so after a while the ride is rough again for a short while. I always used unlocked bars on my rough 2 km driveway at up to around 70 kph.

That's what I like about the Kinetic setup, wheels articulate in alternate wheel bump situations, the rams aren't engaged but in roll the shuttle valve closes internal valves to enable the rams.
It's passive but reacts instantly.
Its why Mitsubishi and Citroen used it in respectively rallye/raid and the WRC until it was banned.

The ride on my old Defender was better on rough roads as it had no bars.

Hi Graeme,

I have one of your speed signal modifiers fitted, just to check that it's working correctly, what vehicle speeds should I see in the ace section of the nanocom when the three different switch positions are used? In the middle setting (off) I guess the speed should resemble actual vehicle speed.

But what about the other 2?

Cheers
