Syvecs Forums

Hello,

I am new to this forum. I am dealing the first time with a syvecs system but have arleady some general experiance with aftermarket ECUs.
Topic:
I am setting up a porsche 991 GTS naturally aspirated engine in an 987. This engine has two resonance flaps in the inlet port/manifold. First flap is actuated at 4200rpm, second one in addition at 6300rpm.

Question 1:
Currently the flap acutation is realized over the function "output functions / change light". Change light status1 at 4200rpm, change light status2 at 6300rpm. --> will change light1 output still be active/on when change light2 output will be active? Or asked differently: Will the flap1 remain closed when flap2 will be closed at 6300rpm? (I am asking this because I could not test it yet and whant to prevent unnecessary issues during first run)

Question 2:
I saw that some calibrations are actuating the inlet port flaps over a custom map (rpm and MAP). Are there any advanteges over the pure "rpm strategy"?

comment: I started a second post regarding Porsche 991 returnless low pressure fuel system in the porsche section. If someone has a general advice I am more than happy to hear it

As far as i am aware from my own setup, the shift light stages remain on even when others are activated.

You could also use engine speed controlled outputs A & B? If they arent already used.

Or spare Fan On/Off?

if two change light outputs are set to activate at different RPM points, it's likely that the change light status will be determined by the RPM condition that's currently met

Why does your quote include random weblinks with no relevance to what is being discussed ? Seems almost spam related. I've removed it for my quote.

Reported just in case.
