If you have a look in my gallery there is an XL spreadsheet that will work out the calibration values once you input the measurements/setting.

I don't know how the IID Tool make the calibration, but i have made mine inside a LR dealer with LR diagnosis laptop.
What it do first, is to open at 100% the crosslink valve in order to have the same pressure in the front and in the rear airbags.
This procedure make sense in order to have all 4 corners balanced skipping the height value.
Then the program make a read of the electrical transducer values at "road" height of each wheel and records them.
After that it raises up the car at off road height and records the highest values, then lowers the car at access height and make the 3rd records. All of these with the crosslink valves completely opened!
After that the system automatically resumes the normal height and closes the crosslink valves.
Your car is now perfectly leveled on the roll axe!
At this point, on the calibration page, appears the values in mm of each corner.
Then it asks to the operator to make a measurement of the distance from the wheel center hub to the wheel arches (in mm) and compare it to the founded value from the system.
Now you just have to see how many mm you need to add or remove on each wheel to make the"read" values of the car balanced and leveled on the pitch axe.
After this the laptop rewrite the CCF with the adjusted values and your car will be perfectly balanced.
I think that is very important to calibrate every corner at the same "pressure" in order to have the airbags response balanced,
think for a while what happens if you correct a leaning car (i.e. on the front), increasing the "height" value via a diagnosis tool, it will increases the "pressure" in a single front airbag, the car recognize it and automatically balance (deflating) the rear opposite airbag in order to level the rear of the car.
This result in a car which ride 2 suspensions hardener than the other, going in a unsafely handling during cornering.
This is what i have learned on my leveling experience. Hope this make sense - Easy-Lift suspension module 4.0

I thought more pressure equals more hight.
Or is it possible to drive at the same hight with more pressure?

I think this is the reason you measure from the wheel centre?07 Land Rover Discovery III HSE

Still working it out...
Good Mowning,
i tried to find out the range of my height sensors with the iid BT Tool by moving the lever up and down.
My Right sensor has a range from -120 to +176.
My Left Sensor has a range from -91 to +55.
Seems like the Sensor is not funktioning.
Today the new one should arrive.
I hope this time it funktions

Nope, more VOLUME equals more height.
You pump air into the airbag, the spring expands, keeping pressure more or less the same. If the spring remained the same size and you pumped more air in, then pressure would increase. But since the spring expands pressure remains the same, but volume of the spring increases to make space for the extra air.Dennis

Yep you are right.
I was not thinking the right way.
So analysing the pressure is only then interresting when the pressure is constantly falling.
My Frontleft sensor had a bad Contact. I have a new sensor with a good contact now.
After i calibrated now all is fine

Hi
Digging old posts...
Can i use the standard iid tool (nit the BT one) to perform the calibration????
Cheers

Hi Ollram
Yes, but you will have to use the manual calibration. More details in the user manual:
