I have recently tried to install a DSP5 switch and tune my truck with EFI live and so far its been a massive failure. I am not getting any voltage from my switch as well as I cannot figure out how to do a full reflash for my lb7 ecm such as the tutorial instructs me to do every time a make a calibration change. The button is not active to do the reflash. if anyone could help i would highly appreciate it.
