So...it's always open above 2700RPM regardless of flow conditions. I don't see the point of doing this "flap mod" if that's the case. Who drives these cars under 3K RPM anyways?The dealer sent the following that shows the algorithm of the flap operation with the following note:
"There is an algorithm that controls the flap. It takes into account what gear the transmission is in, engine rpm and air quantity the engine is ingesting. The attached chart shows all parameters for operation of standard exhaust and sport exhaust. "
I am still not able to follow on how to create conditions so I can actually witness this flap working as it is always open after I have been driving behind our Macan. If anyone can interpret and post back a sequence of steps on how to make the flap close, that would be great help to me.
