I have seen a few references here and in other threads regarding Ford pushing ECM and/or PCM updates OTA (Over-The-Air via Cellular modem) w/o their knowledge.
Let me very clear here: Ford will not and Ford cannot push ECM or PCM updates to your vehicle via OTA Cellular modem or WiFi
= Your truck must be attached to a laptop in order for Ford to update ECM or PCM programming
I spoke with my dealership's Service Manager today and the only things that can be done OTA are:
1.) Sirius XM updates (done via their receiver via Satellite)
2.) Ford Sync Updates
a.) via OTA Cellular modem (if you have paid AT&T for WiFi connectivity)
b.) via a WiFi HotSpot on your cell phone
c.) via your home WiFi network (if you can park your vehicle close enough to your home/business)
My Service Manager assured me their is no technical method in place today to push ECM or PCM updates to your vehicle automatically.
= I am not saying that isn't possible/feasible, but rather Ford has restricted this functionality and is not currently doing this
= I am also not saying that they may not do this in the future, but they are definitely not doing this now
