Hi All,
Thought this might spark some ideas.
For those lucky enough to own a PSP it is possible to use EFILive on it. Using some homebrew software on the PSP you can do like a remote desktop hookup with a PC.
The PC can be connected to the vehicle and you can then use the PSP to control EFILive on the PC.
