new to efi live. I have a buddy helping me get going since he has used the system for 5+ years. I have tried plugging into both a 07 lbz duramax and a 15 lmm and It wont even let me view the PIDs...if I open it in v7 it tells me to check firmware and use v8 but when I open it in v8 it reads 0 all across the board. all software and firmware are up to date so I'm stumped. any help is appreciated. thanks
