Turns out the E86A.pmm file is mis-configured to retrieve the OS using $1A,$C2 (which is the speedo segment). E86B suffers the same problem.
I've attached updated *.pmm files to correct the problem.
E86_OS_Validation_Fix.zip
Download and unzip the two files into the folder: \Program Files (x86)\EFILive\V8\Config
Note: The 12641475 speedo number can be manually removed from the drop down list by editing the file: \Documents\EFILive\V8\Config\PIDs\E86A.pxl
