    Extended Height Mod

    I have been looking at the Johnson Height Rod Modification which gives and extra 2 ½ inches of lift.

    http://www.landroverworld.org/forums/showthread.php't=20853

    One of the problems I see with this is that it is a mechanical mod that I would not want to install permanently and taking it off /on as needed will eventually loosens the joints.

    Being from an electrical background I was wondering if anyone has looked into an electronic solution for this.- my idea would be to have the standard Access/ Normal/ Extended heights but by adding in a resister on each sensor and a common switch you will be able to offset the potentiometer and “fool” the system into extending above the extended height. Basically you are building in a switchable electrical offset.

    What’s good about this is your vehicle remains standard for on and off roading and with one switch you can hyper extend it only when needed.

    Does anyone know the potentiometers resistance (Ohms) values at Access, normal and extended heights – that way I can calculate the size of the offset resisters.

    You mean something like this

    http://www.aulro.com/afvb/verandah/1...d3-d4-rrs.html

    Made by a member on AULRO and I have one fitted to my car - works great.

    Also for Rods I would be using Gordon's stuff - better than Johnson rods.

    Ditto No3 for LLams except be careful if doing a handbrake manual release while on a track needing the super exented mode to get in and out My fault I broke it

    I travelled this route initially until I discovered that the sensors produce a regulated voltage. My Llams system converts the analogue voltages to a digital representation, modifies the digital values as appropriate then outputs acceptable PWM pseudo-analogue signals.

    I've got the GOE rods. They're low tech, they work, are easy to remove and set up/down, and inexpensive. To change from off road to normal takes me 2 minutes.

    Me too. If I have a suspension issue that needs land rover to fix, two minutes to take all 4 off and put the factory ones back on. This is what helped me make the decision over LLAMS. Best not to mess around too much with the discos electronics.....that the way I feel anyway.

    Gordon from GOE has a simple no nonsense solutions in these rods.

    Im amazed that lovers of such low tech (read cheap !)solutions would ever consider owning such a High tech 4WD solution as a D3/D4/RRS . Whether you like to believe it or not , electonic componentry is a factor of 100 times more reliable than its Mechanical brother .
