Has anyone installed the factory launch control to one fo their cars that was not equipped with it, and if so was it an easy install?

If by launch control you mean sport plus then I had that installed. The dealer needs to order a new button module for your car (not just one bottom but the left side bottom module) and the rest is just a software update. I haven't actually tried launch control but I'm sure it works given that the other features of sport plus work.

I don't think it's possible to add on older Macans though but the dealer can verify with a vin check when they order the parts/software anyway.
