Swirl flap delete VAG 3.0 tdi EDC16 .
People are often interested in Swirl flap delete via the ECU because some cars have plastic manifolds with swirl flaps that fail easily and set an engine warning/error code. The manifolds are expensive to replace. Do not just switch the ECU software. You must modify the manifold as well. If you do not modify the manifolds, the flaps can break, fall into the engine and Bang!!
There are at least two different ECU map layouts for swirl flaps in EDC16 files.
The simplest is shown below in 2D view.
The swirl flap control consists of a main Duty cycle map plus 2 or more correction maps. The correction maps seem to be for temperature and air pressure.
