I can get a new one thru a friend who works at the local ford dealer cheap, and I have another friend with an IDS that can program it, but....
Is it going to erase/write over/try to update my PCM when I install and program the new FICM? Will my FICM tuner still work as long as I return the old FICM to stock before I change them out? Yes, IDS will reprogram the PCM when it programs the FICM. Here is what i would do, return your old FICM to stock, get the new FICM and have your buddy at the ford dealer program it on another truck at the dealer. Afterall its a 6.0, odds are pretty good there will be another one in there getting work done on it. It wont matter what year it it. Have him program it on another truck and remove it and install it in yours after. Then reprogram it with your FICM programer.
