[Prologue]
First of all, let me explain to you why I needed to make this PSE Control Unit and decided to provide it as a Complete DIY Kit.
In May 2015, I imported the Porsche Sport Exhaust System (PSE) and tried to retrofit it to my Porsche 911 Carrea S (Type 997.2).
And I planned to control the PSE with the Combined Switch on the center console, as if it were a genuine Porsche option.
