Hi there. I purchased a 2000 FRC vette last November and have added a few parts to the car. I just installed an LS6 intake manifold along with headers an X pipe and highflow cats. I have also just purchased EFI live and an Innovate LC1 (which was installed with the headers and X pipe). Do I supply an additional ground to connect the LC1 to the V2 scanner? As far as I can tell I am supposed to use the brown wire from the LC1 for wide band logging and the included adapters have a pos and neg markings for the scanners analog inputs. Also I downloaded what I am assuming is the stock calibration from the PCM, when I tried to open a tun from a 2002 Z06 that was included with the EFI software I get a message stating the tune has a differant OS and no comparison will be attempted. Do I need to flash to a differant OS? Are there tun's posted from members with similar mods and would that be the best route to begin with for a complete newb like myself? Any advice is much appreciated.
