I have the equipment so I do my own PCM/FICM/TCM flashing on Ford vehicles. You will need to disconnect the Edge before flashing. I tried to flash my '03 F350 with an Edge connected and when I tried to do the flash, I kept getting an error when the computer tried to rewrite the PCM or any of the modules. When the Edge was disconnected, the flash would take just fine.
You will just need to unplug the Edge from the PCM and plug in the original OEM wire harness. Any connections to the MAP or EGT pyrometer may remain connected.
Being the owner of an early '03, I would highly recommend the induction heat flash. The buzz flash didn't help much at all. It was just annoying. Even though it only gets down to about 25 deg. F in the winter, it made a huge difference in starting and drivability while the engine is cold. Since I have a manual transmission, I can't comment about the Auto shift patterns or Tow/Haul.
