2013 GTS Start Up ECU Mapping
Hi All,
Long time lurker, first time poster. I appreciate all the great info guys share here and I've learned a lot and love the car. So my question is one I'm sure no Porche guy asked, ever, and I may have to turn in my man card but here it goes.
When I start the car it revs to about 2500 rpm and is quite frankly a bit obnoxiously loud. Due to the location of my garage, neigbors, and kids room it's too loud as I often leave for work in the middle of the night and wake everyone. Not to mention I look like a juvenile when starting it up anywhere else. I know it doesn't have to rev/start so loudly since when it restarts using the auto restart function it restarts like a normal car.
So my question is does everyone else with a GTS experience the same thing and can the ECU be reprogram to not rev so much on the initial start? Thx in advance.

I believe that the valves need engine vacuum to hold them in the quiet position (closed?). They could be held closed during auto start/stop since that only lasts for a brief period of time, but I doubt the vacuum can be held for longer periods of the engine being off.

I can't answer your question specifically, but in general many cars have a cold fast idle to warm up the catalytic converters ASAP for improved emissions. Maybe that's what Porsche had in mind. Since it's a normal idle when warm this makes sense to me.
