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?
