I recognize that name... Anyway, the command you're looking for is rep (factioncodehere) (value between -1 and 1) -1 will give you a fully negative rep, and 1 will give you full green. The faction codes themselves can be a bit tricky. Take a look in the text file initialworld in Freelancer's Data folder. It lists the starting characters rep with each faction by code. You should be able to figure out which is which with a bit of playing around. I'll be able to give you a more detailed answer once I get to my computer later tonight if you need more information.
