lc1 wideband output ?

on the lc1 wideband it has two outputs. output 1 to simulate a narrow band and output 2 for running a gauge. In the efi live manuals it state to hooked output 1 to a dyno tune and output 2 to efi live.

I have hooked up output 1 to the pcm. My question is can i hook up output 2 to efi live tunes and program it to run with efi or can you only use output 1 with efi live tunes?

The outputs come pre-programmed,
#2 connects to Flashscan without needing to be re-programmed.
#1 will not work properly with the pre-defined LC-1 PIDs unless you re-program it.
