My GT4 is arriving shortly and I am hoping there is some way to permanently disable the Start/Stop feature with cylinder deactivation. If I understand correctly there is a button allowing this system to be deactivated temporarily. Is there a permanent fix?

Interesting question.
Every time i start the engine automatically i press on Autoblip, Exhaust ad Start/Stop....

Yes, I have programmed my brain to push the button at every start , permanent brain programming that is, or a habit.

I veyr much doubt it unless its a PIWIS option ...

Interesting. On my MY20 Macan it stays off with every start (after I turned it off and memorized it to the key - could that be the difference)

Yes they are part of the 4 buttons I press on start up - exhaust, Stop/Start, autoblip, ride. I also was under the impression you could keep SS off permanently.

Depends on region, US spec cars once you press the Stop/Start button off, it stays off from that point forward unless you turn it back on.

@katzndogs can you confirm for us in the US that US 718 GT4s/Spys allow to still press Auto Stop / Start and it stays off until you turn it back on? Or does the car reset the off switch every time re-start the car?

That will be very annoying if it does not "remember". To someone else point, eventually you just add it to the "flight check" when you enter and start up the car. I used to have to do this with lane assist in my last car (stupidest feature ever)...annoying but becomes second nature after a while.

It does not remember (in Canada).

I usually deactivate it but I tried it a few times and cannot get it to actually stop. Probably because of AC

I have had my Spyder for just one day now and drove it top down. I left A/C off and the start/stop deactivator works!
I shall try with A/C on and see what happens.

My A/C always defaults to ON. Anoying...

Nothing in the manual nor settings, it seems you have to pull a wire:
I've typically left it because the button also controls the cylinder de-activation, and the car gets really impressive mileage (20mpg+) in even 2nd / 3rd gear (stuck behind slow vehicles on back roads). Freeway mileage no so good though, only 25-27mpg. Compared to like a Corvette with cylinder de-activation enabled, which gets 30mpg highway but more like 16-18mpg at slower speeds (it'll only do cylinder cut-off in 4th gear).

That said, the Porsche stop-start thing is way way less annoying than the Corvette forcing you 1st to 4th thing, which never has in my observation been healthy for the motor nor actually saved gas... the GM engineers who bolted that feature on at the end were not the smart ones.... GM probably could have lobbied around it if they hadn't gotten convicted of that ignition switch fraud. In contrast, Porsche did a good job here with the dieselgate-mandated features of stop-start and cylinder shutoff-- it's actually usable.

Is this what you have to do? Leave the A/C off, then you don't have to click the deactivate/start stop everytime?
I have a US spec car. I have to push the button everytime.
