GT Speed spoiler raise & lower MPH

[Sunnysidebb]

Good evening,
I would like to lower the speed at which the rear spoiler raises automatically on my 2008 GT Speed using VAS 50504A
Does any one know how to do it. I've been over 2 hours going through the Masks and can find no reference of raise and lower default speeds/ settings ?

Any help please??
Frank.

Sounds like a lot of trouble. There's a button you can press to raise it at lower speeds than the 91mph it automatically goes up at.
