You can throw the whole ficm in. There are different flashes for them depending on how old truck is or last time ford flashed it.
I burned one up in my truck where one of the resistors fried and it quit. Purchaced 8 new 0.0075 foil resistors for .49 cents each and soldered in the replacement part easy enough. I doubled them up for the hell of it and it's cruising away at 48 volts all the time. Also reflowed solder on all the places they recommend when you work on them.
One thing about a older flash you can wind up with the buzz flash that cycles injectors for 20 seconds after you shut off truck and it might make you crazy listening to it buzz away after your walking away from the truck. lol
I think thats a 05 or older flash,I have 3 ficms and one has the buzz flash took that one out because of it and it has lower hp for whatever reason. Repaired my old one truck came with and it's much better on throttle response, has something to do with pcm flash working with ficm flash. So it would probably be in your best interest to keep your logic board, was in my case.
