Also what inputs do you have available because the 07 expedition and navigator are completely HS CAN controlled to send info back and forth from one module to the other what stuff is stock from the expedition and what has changed (abs, pcm, mechatronic tcm, etc). I can try to help out and see if we can get it working correctly saw you are using a tone rig for rpm ad other stuff you added to assist with the gas pcm to run the diesel motor?
also saw you are going into limp mode or the wrench i was able to get rid of this issue when i did a trans swap on my 08 expedition prior to changing my system completely.
Ill send you a couple thing to try personally on your truck I think its fully possible to get it working.
