Only answer anyone on here can give you is "Ask your mapper" as it MAY be disabled in your software.

A million people will now tell you it is always disabled in Pectel software, well, i did some testing with one last week on L8 and it IS NOT. It has teh same 6 degree retard map as a std file. P8 may be different.

Ask the mapper.
