NOTE: Not all Supported controllers can be read.  Some vehicle manufacturers have disabled the ability to read the contents of a controller from the factory.  In these cases, EFILive customers will need to obtain base files from an alternative source. Some EFILive Custom Operating Systems are written to non-readable memory.  These files cannot be read from controller.  Refer to the Problems Reading a Controller  article for further information.

Follow these steps to read the selected controller.
