Thread: LLAMS electronic height controller for D3/D4/RRS

Sorry, I should have explained at the start.

Fade-out reduces the sensor adjustment value when operating near the upper height limit which reduces the incidence of the suspension ecu trying to get more height from a corner when its fully extended. It works by decreasing the adjustment once the real sensor signals reach a predetermined point so that the sensor signals eventually match the actual height as the suspension gets close to being fully-raised. Fade-out is unlikely to cause any reduction in achievable actual height.

If this change is implemented then probably best to have fade-out enabled by default in which case the module LED would show yellow if fade-out is disabled rather than enabled, ie when not the normal operating mode. Thus the default setting would provide the most robust logic although the incidence of faults is quite low without fade-out enabled.

Edit: Fade-out is currently too restrictive to have as a default so the proposed changes are on hold while I see if the limitations can be reduced to allow more height yet still serve the option's purpose.

Another LAMMS installed. Great bit of kit! I had a small issue with the rotary switch, where I had six positions instead of the noted four. Thanks to Graeme for his super quick response to my PM even though he was offline at the time and on new years eve. Turns out when I removed the knob, the tabbed washer came off (which it shouldn't) and I fitted it back in the wrong location. Graeme's response below explains.

'The switch is not correctly configured so please don't connect it to the module with power to the module as it may cause a short circuit on the module's 5V supply. You are correct regarding the expected positions.

There is a movable limit tab washer under the nut and washer that is supposed to be super-glued with its tab in the 3rd hole but I suspect it has come free and has ended up in the 6th hole. Can you remove the tab totally then rotate the switch shaft fully anti-clockwise then put a small dab of superglue on the short section where there are no holes then fit the tab in the 3rd hole? Be careful that glue doesn't go down any of the holes. If the fix doesn't work out then I'll send you a new switch.'

I used a smear of silicone to hold in place instead of superglue.
Pics below of the tabbed washer and I also found a perfect safe spot for the Mode pushbutton. The hole is already there, just needs enlarging to the correct size.

Cheers, Mungus

It has come to light that the default calibration values for 2005-2009 Discovery 3 (LR3 in the USA) are not compatible with 2005-2009 RRS. Suspension faults may occur and Llams may not cause height changes. Therefore until a version of the module is available that caters for more than 3 default vehicle configurations, MY05-MY09 RRS must be calibrated using actual values learnt from using normal height then off-road height in the original calibration method.

A new module is under development that uses DIP switches to cater for up to 8 default calibration configurations to support MY13+ RRV, MY14+ RRS and presumably the D5 so one will be added for the 05-09 RRS.

Thanks Graeme, my LLAMS which has saved my bacon on several occasions in very deep water and on very rough mountain tracks since I installed it on my D3 over 4 years ago is again ready to help me.

After sales support is very much appreciated and your help and advice is exemplary.

You refused my offer to pay for the part (wiring loom) but I hope you don't object to strongly to the bottle of wine being delivered to you soon.

Thanks NavyDiver for your very kind gesture.

DPL shiped me a Llams unit yesterday and I do not have the red mode push button and I mising something? also the instructions are from 2011, do I have an old unit? I will try and ring them tomorrow but I'm not sure if they are open on a Sat.

Its possible that DPL may have found a very early kit. I'll send you a PM.

Edit: Yes, a very early one that hasn't even been updated with the "recovery" option - not appropriate to be supplying this long since having been superseded.

TIA.

Did we find a good spot? I have a MY12 RRS and I'm also looking..
