What's involved in coding a PCM for a MOST component?
 

I need to have this done so it will accept my Tooki. Is it time consuming? Any idea what it should cost? I'm ignorant to the process and don't want to get a bill for $300 for a process that takes 30 seconds of button pushing, so I figure it is best to get some insight. Thanks.

Porsche System Tester (PIWIS) is connected to the OBD port. Should be under 15 minutes by a dealer tech.
