livewire monitor

[04_6.0]

i was wondering if the SCT livewire was able to monitor the fuel pressure on a 04 6.0? It has the line to select to it just says error when i load it up to the monitor screen? And i have two eot lines to pick from. eot gives an error message. And eot_v works but gives really wack reading like on start up it is usually at 700 then slowly drops to about 190-200 on a long trip. Do i need to update my unit or somehting? Any help is greatly appericated.
