I just got my FC black box installed in the car and the datalogit software installed in my PC. I'm trying to et the PFC to connect to the datalogit fallowing the instruction on the screen but its stops at waiting on FC box. Then it keeps asking if I have the ignition on (I do) but nothing. All the LED light up and the commander is working fine. I'm just trying to switch my fan switch temp.

 

I always start with the obvious... Double check all of the cables, make sure the cord from pfc to datalogit is plugged in all the way. Also check that you are using the correct pot number for your serial cable

 

Figured it out. Needed to installed the USB to serial adapter.
