My car
2000 3.2 manual
If i wanted to install a row tune using the PIWIS, are other steps involving the immobilizer required? and would I be able to go back to a US tune?
Tinkering with the PIWIS coding/programing portion and got to this "important" page mentioning the immobilizer. I saw tunes in the drop down for "Boxster S manual RoW" but nothing for US.
Pictures of the steps i took and the "important" message.

Sorry, blurry pic but setting selected are for a 2000 3.2 manual RoW tune
