They are the actual settings for that height. This can be confusing for some, in that the height setting for each position is actually a measurement from axle to bump stop. Or as some have done a measurement from centre of wheel to wheel arch. The readings from the sensors can vary dramatically with the vehicle sat straight and level. So as such there are no default that you can set each corner too and have the vehicle sat straight. These settings vary sensor to sensor. There are however a set of default settings for each height built into the ECU these are reverted to if you exceed the paramiters for a sensor at a given height. But they will not guarantee the vehicle is sat level. For instance at standard height the paramiters for setting the fronts are 95-150 the rears are 85-130. Depending on the signal from the sensor, with vehicle sat level at standard height, the readings could be NSF 108, OSF 115, NSR 95, OSR 121. Or any combination between the acceptable paramiters. So you can see that there is no set value you can put in. Each has to be set individually to get the height correct. I would recommend strongly that you write down any settings before changing anything. So you can revert if you get in trouble. If for instance you decided to set the fronts at mid point on the paramiters, say 130 and the rears at 120 i can almost guarantee the vehicle will not be level and will not be at the correct height. So whilst there are defaults in the ECU that it can return to if it has a bit of a fit, they do not mean everything will be straight and level and at the correct height. Also there are NO standard settings for the sensors each has to be set individually to obtain correct height at each corner at each ride height setting.
