But yeah, I found a guide on how to do it with ESYS as alpina comes with PSZD data aswell so I'll hopefully flash the map this weekend If I can get the psu first.

If you only want to flash the Alpina software you don‘t need the power supply.
The Alpina flash takes only 3 minutes.
The battery can do this even without a power supply.
I've done this several times.
