Sport vs Standard Air Suspension

[Versace]

Hey guys,

I have a D3 with the standard air suspension, and I will buy another (W12) with the Sport suspension option. In my opinion it is way to firm, how can I "degrade" it to the standard suspension? Some say I only have to fit the suspension computer that is under the glovebox for the standard, non-sport one. Is this true? I know that the air bladders are completely the same, also the dampers are the same lenght, I compared them!
