Land Rover Discovery 2, testing the limitations of A.C.E and T.C

- My 2000 Land Rover Discovery 2 is equipped with A.C.E, or Active Cornering Enhancement. A system which utilizes a culmination of electronic computers, sensors and two hydraulically pressured rams which stiffen or loosen tension on the front and rear sway bar assemblies. On road, this means very little body roll, confident cornering and stability. Off road, the system completely slackens the sway bars, essentially disengaging them automatically when needed. The system is “intelligent” and requires no user input. The suspension articulation is impressive.
Nice see someone that knows how drive over obstacles thanks for posting nice Disco 👍🏻
Beautiful demonstration of the ACE sway-bar disconnect. A significant feature of those vehicles.
Nice demo. Good to see that you know how to use the TCS. Gentle and persistent, and it just works. No need to spin the wheels too much.
Great video, thanks for sharing, your video shows the capability of the D2, I’m a D2 lover/owner myself and love taking it off-road!
Very capable rig!! Looking at finding one myself. Thanks for the demo!!
very well driven mate.
As slow as possible, as fast as necessary.
Cheers for sharing.
This is amazing car. Nice job behind the wheel too.
Very good driving in a very capable vehicle.
Land Rover had a video of an ACE equipped Disco doing high speed slaloms with a non-ACE equipped Range Rover on a trailer. It was one of the best demos of what it can do. You can have full sway bar disconnect or a sway bar the diameter of Arnold Schwarzenegger's thighs dependent upon your needs at the time.
Fantastic video - best I have seen demonstrating TC, ACE, CDL, and why Discos are just mountain goats. You should reshoot it exactly the same with a Jeep buddy with you.
Good video - thanks for posting!
Very controlled driving , good work
Thank you! More videos to come.
Love this videos you got man. Looks like you are in my neck of the woods too
Thank you! I am located in Nanaimo and often exploring the Cowichan Valley. Are you on the island? I watch and thoroughly enjoy your channel. I’d be stoked to see your Range Rover in action.
The tire size you listed doesn't seem to exist. Did you mean 285/75R16? Nice setup and I like that they don't rub!
Nicely sorted D2, it definitely has more front flex than standard non-ACE model. What lift & springs are those, Terrafirma 2''?
Thank you. The setup I am running is the Terrafirma 2” lift. Up front I am running the medium duty springs, in the rear I am using the factory rear air bags with a 2” spacer. There are Terrafirma all terrain shocks on all 4 corners. I have also upgraded to Terrafirma drag link, stabilizer and track bar.
Terrafirma confirmas the noobs
She’s a beast
Hello, nice vidéo, I have a Disco2 TD5 from 2002 with ACE. I just changed the front and rear cylinder of my ACE as well as the ACE filter. However, my ACE system goes into alarm and moves the vehicle in a roll before going off into a red alarm. Would you be so kind as to tell me how to adjust the cylinders after reassembling new cylinders, so that the ACE works again. Please use simple words because I'm French and I don't know all the technical words.
Nice a fellow BC discovery
I believe I’ve seen you post on the B.C Land Rover page on Facebook. Cheers!
Hey I have a question does the ace system in low range actually provide more articulation by allowing the hydraulic ram to have play and travel like a sway bar disconnect kind of? I always hear what it does on the street to stiffen up the sway bar but just curious if it does the opposite in low range to actually give more articulation the opposite of on the road
That is correct. I believe there are 3 settings for the ACE system determined by driving conditions. The system will apply maximum sway bar stiffness during regular driving and during hard cornering, then the second setting occurs when driving on bumpy roads - the system allows some slack to improve the ride, and finally in 4 low, 10km or lower, the system removes all hydraulic pressure allowing full axle articulation. It is a really great system.
I drive a non ACE one bit I’ve tried/driven several units with the ACE….people: that was 1999!!!!!! That thing is still unbelievable nowadays….
You can drive it in roundabouts as if it was a stolen car and it stays flat as a small sports-ish car…but offroad it’s got more travel than the stock pne, so most of the cars of its era…
That was some engineering
When you did two inch lift did you put longer ABS lines and brake lines or was stock length Okay for 2 in? I hear conflicting answers but if I don't have to I'd like to not extend mine. I bought mine from somebody who put 1.5 inch ome HD Springs and I'm thinking I want 2 inch medium
Hello there, I did not extend the lines. However, I’m not sure if ACE comes with longer lines from the factory or not. My friend who has a disco lifted his 2” with no issue. I would say you are fine to leave the lines.
@@VanIsleDisco oh that's good yeah mine has no Ace or air from the factory
@@ronaldrrootiii6040 my newest disco - an 04 has no air or ace. I will lift it 2” with 255/70R18’s. Unfortunately I crashed this black one
What size tires
Hey bro do you find you breaks a pretty soft compared to other vehicles?
Yes, I do. I have new brake pads and rotors on mine. Have had the brake system bled manually and flushed with a machine which controls the ABS. Still a soft pedal. The brakes are strong though. I can pull off a pretty good stop with mine. But I’ve always thought the pedal was soft compared to other vehicles I’ve owned.
@@VanIsleDisco k good to hear same with my disco.
Hey, you're in BC... I have a Discovery 2..let's go wheeling! .. @604x4BC
Where’d you get the shovel mount
I just used a rubber tether and hooked it through the rim and onto the spare tire carrier. Very rudimentary, but it works well
Hi Aidan Manson, what's that magic switch i the 1:16 minute of the movie?
My Discovery did not come with a centre differential lock lever, but the transfer case was equipped with the internals. I built a bracket and device to lock and unlock the CDL electronically. It works great.
@@VanIsleDisco Interesting idea. My D2 doesn't have a CDL. I use only TC.Maybe someday, when replacing the clutch, I will install the CDL...
@@MichalG_4x4 it certainly makes a big difference. Traction control works great for the majority of off road driving, but for some of the harder challenges, waiting for traction loss might just cost you necessary momentum. I mostly got it as a safety precaution. If TC fails, I might not be able to get out from the bush. The CDL ensures that I will always have 4 wheel drive if traction control fails.
Always 4 wheels! Unfortunately, you can't get it with just one locker in the transfer case. On the other hand, you have a minimum of two wheels only when the axles are crossed. One at the front and the other at the back. In a full-opendiff configuration only one wheel turns when the other three remain stationary.
To realy get 4W turning, front and rear lockers have to be involved
@@VanIsleDisco do you have a write up or a video on how you made this bracket and switch? Thats really slick!
At 3 minutes 30 seconds I'm surprised the front driver tire didnt spin more at first before TC kicking in. Were you left foot braking before it lifted?? I know it takes atleast a little spin. In this clip it acted better than modern Rover TC. How???! Hahaha

Hi there, I really enjoyed your video, I am putting together an off road compilation of the Discovery, and wondered if you would like to be included?
Thank you! I would definitely like to be included.
@@VanIsleDisco Thank you, I will be sure to credit your channel as the source of the footage.
@@VanIsleDisco Thank you for your contribution, here is the link to the compilation ruclips.net/video/Sv-g_Gdl_u4/видео.html
Can you share what system or parts you are using for your cdl ? I saw thats it is electronic
Here you go my friend

Ace disconnects under a certain speed
ACE is functioning at all times depending on vehicle speed, bumpiness of roads and various other computer monitored factors. In the video, I have shown how ACE reduces hydraulic pressure to the sway bars, allowing them to twist freely with little to no resistance when driving off road. This increases suspension travel to keep wheels on the ground better than a vehicle with traditional sway bars.

А у этого движка оже колено ломается?
в этом кузове если дизель, то совсем другой рядный пятицилиндровый
Why are you on the bakes, while on descent control😂
Sometimes the hill descent control allows too much speed. Applying the brakes when there is sufficient traction is fine. The transmission was in 1st gear, and even then the speed can increase too high for certain hills.
@@VanIsleDisco This problem is not as present in the Diesel Disco 2's. The compression factor of the diesel is pretty much double that of the V8 thus engine braking is more severe. My D2 is diesel and when I put it on 1 and then engage HDC it will descend slower than a V8 will. This was LR's first attempt at HDC and I think they probably didn't factor in the lower compression of the V8's over the diesels properly when they calibrated the systems.
@@landrover1155 Can't comment on the 4.6 V8 we didn't get that over here in the Disco 2. We had the 4.0 V8 with a standard 9.35:1 compression ratio in the European market and regions. Also a manual gearbox on a V8 is a hell of a mod and 1st gear in a manual is lower ratio than 1st ratio in the auto which also has the handicap of a slipping torque converter. So it naturally would engine brake a lot better.
Looking fantastic, even though the home of the world beating 4x4 is the uk you can’t truly off road here because there’s not enough green space and then there’s always some moaning tree hugging rambler saying it’s dangerous so all the paths are closed to off road bikes and landies it’s all about elf and fucking safety allegedly…….killjoys
That is a true shame. Here on Vancouver Island there are plenty of unique offroad situations to experience.
If you have the CDL engaged you're not really testing the TC.
Traction control works great alongside the centre diff lock to mitigate traction loss between left and right wheels. I do have other videos showcasing traction control working it’s magic. But we all know that it has its limitations, and is only benefited by adding the CDL
