Hello 911 Pilots!!
I designed an original electronic circuit and made a printed board. It can control Porsche Sport Exhaust System (PSE) as you want.
First of all, Please watch this movie.
I analyzed the electronic circuit of "Combined Switch" from your information.
Thank you very much!!
I checked the voltage and the current of "Combined Switch" and "Solenoid Valve".
Then, I made an original electronic circuit for evaluation on a bread-board.
This is the smallest micro-computer in the world.
I wrote a controlling program for the micro-computer.
This is an original electronic circuit for controlling PSE which I made.
I designed a printed circuit board in order to increase the reliability for implementing to Porsche.
This is an original printed circuit board.
This is a prototype circuit for controlling PSE.
This circuit has some fail-safe functions for implementing to Porsche.
I checked the operation of the prototype circuit on my desk.
