The programmable module installation option is only a possibility on any tool that offers it if the original PCM is still capable of communication since it needs to pull some fields of information out of the old module before installing replacement.. I thought the diagnostic and service functions of an MP808 are identical to those of an IM508, Just being Level 1 tools offering no active tests. I thought virtually  the same as an IM508 since the IM508 is based on chassis of either the MP808 or the MK808, I forgot which , but aside from the Immobilizer and Programmer, and a few hot functions the IM508 has, the service functions and diagnostics of the MP808 likely mirror the IM508 as a basic level one tool.
