Anyone with PIWIS?

No, just a Cayenne with an AGM. But it works fine to maintain voltage on the Taycan.

My only concern would be sudden voltage drops or dips. I’m looking to do ALK and Matrix headlights and I heard those can take a long time to complete

I'm no electrical engineer, but I think you just want to prevent battery drain from letting your Taycan 12v drop too low from all of the accessory usage, and a running engine with jumpers will keep the Taycan battery voltage up while hooked up to PIWIS.

I agree 100%. I’m no expert, so I asked Gemini about this very thing a few days ago and it strongly advised against it. What have you done with you car via PIWIS so far? How long did it take to complete the tasks?

That's funny, because it was Gemini who originally recommended the jumper cables. I did the LED matrix upgrade on my car. It took me all day, but mainly because I was ultra cautious in navigating PIWIS for the first time. If I were to do it again, it would probably take about an hour.
