Figured this may be a different question from my other post.

I know pcm family matters.

but I have a 2000 expedition 4.6. 2wd eddie bauer.

may need to flash a pcm for it.

I purchased a 2001 2wd 4.6 eddie bauer pcm that's a different family from the junk yard. Will it flash?

I purchased an entire 1999 expedition 4.6 2wd xlt differen family. Also runs coil packs over coil over plug. (Cop) will it flash?

I do not have a forscane tool. Will be taking it to the dealer to flash. Swapping pcms in the drive.
