Only curious, but if I were to buy an IID tool would I be able to raise the current off road height by as much as 50mm? Is that a safe amount? Is there a recommended safe increase in off road height?

As I say It's a question based on curiosity and maybe the Shiraz.

The car will only allow you to raise or lower it within the working tolerances

not sure what the max increase on height is possible but if you up the offroad height then the standard and access will go up the same amount. ... - .- -.

Thank you chaps.

Only in pre 2006 RR, you can adjust the heights of each level (access, motorway, standard, off road) separately. The later vehicles can only be adjusted together (all levels +10mm, etc.) Ex-FULLFATTY now downgraded

Anyone able to say what the standard height setting on the IDD is for a 2006 MY 4.4 AJV8. I have looked at the setting and can go down about 5 and up 20 something from memory. If I drop or raise as far as I can (drop would be easier) how many units would I need to raise to get to standard. I am looking to set all 4 together rather than measure individual wheels.

What does each unit on the IDD represent in mm. There is a difference between knowing your sh!t and knowing you're sh!t

Hi J90,
On the 2006> L322 you have a possible adjustment range of values between 150 and 250. These values are calibration values in the EAS system and do not correspond exactly to height measurements made outside the vehicle because the height sensors only report values close to linearly around the middle of their travel. The further the sensor goes away from the middle of travel, the further the values deviate from linear. Around the middle of travel, the values are close to 1mm/value. On a L319/L320 you will have a little less than 100mm adjustment range from full bottom to top - the exact amount of how much you can raise or lower depends on where the vehicle's EAS is calibrated within these ~100mm. This means you can have a max of around ~50mm up or down, though in reality it is usually less.

Due to the position of the rear height sensors on the L322, there is even less travel available leaving only ~30mm adjustment up or down at best. Most vehicles will be less (our 2007 test mule only allows 22mm height increase).

You can achieve a little more lift if you use rods (EAS height sensor couplers) in conjunction with the EASControl or IIDTool.

All that said, nearly an inch of height increase may not sound like much, but it is plenty for the stock suspension. You will have very little droop (down travel) left on the front struts and if you are not able to keep tires on the ground, you have no control. More lift without other modifications will become dangerous.
