How to change USA country code to Rest of the World (ROW)

[gorichville]

Hi,

I would like to know how to change the country code of USA to Rest of the World. My car came from California and shipped to the Philippines. It is a 2008 boxster s manual transmission. The car emission in California is very strict and lessens the car's performance. I tried to change the country code to Rest of the World but other areas of the car like the alarm and door lock don't work properly. Can someone please explain the proper way of changing the car's country code the right way.

Thank you!

I'm not sure you would want to change the country coding in most of the control modules. For example, as you have found, by changing the alarm country coding you have set different remote frequencies on the control unit, so the key remotes you have won't work.

It sounds to me that what you are really looking to do is change the fuel map in the DME to a RoW map. Other than that, and possibly the radio frequencies for your region, there's no reason to change the country coding in any other modules.

This is done using a PIWIS unit, which tells the DME (amongst other things) to ignore the second O2 sensors (a traditional "fix" for the CEL on US cars that run headers without the second sensor). I am not aware of any other system that can correctly change this..................... I've seen multiple cars in the shop that have had this done, none exhibited the issues you mention.
