A) how the heck do you know all of this...great infoHi, I will try and get them off of mine but there has been a total of 2 IPMA updates. he first IPMA update resolved a clarity/Resolution issue with the camera system. The second was not specific to the camera in motion but that was included. Also if you have the latest update and still do not have motion you will need to adjust as built in the APIM as well. I used a 21.5 as a guide. You could maybe use the forscan dropdown style configuration also to adjust yours to remove the speed limits. I just found it easier the way I went with it since I knew the speed restrictions were resolved in those truck.
Unfortunately the IPMA will likely not get OTA for these updates as they are so large and can cause too many issues if they do not complete. Since the IPMA controls so much of the vehicle. It is one of the most important modules in the Truck. If you look at the operation charts for the 2021 almost all runs through it. If it were to fail during an update it would be a big problem for ford and this update is huge. I do understand a portion of the time required for the update is due to the Canbus data speed limitations but the update took me 6 hours or so on a 360 cam IPMA. Could be less for the rear cam.
My understanding(Could be wrong) The ethernet is only for OTA, the gateway downloads the update(8GB limit) and then transfers the update through ethernet to the module. Modules with Ethernet. APIM, TCU, IPMA(If Update is Small enough), Gateway(Some that have an early build that have not received OTAs as of now need to have the dealer manually update their Gateway as it was the issues causing OTAs to not work), IPC, B&O Amp. Again I could be wrong but its what I understand since the ethernet has a much higher data transfer speed.
I have received all the power up updates including the latest 2.1.1 and prior the 2.1.0 and neither address the IPMA. The 1.7 was an APIM update to 21146. I did that one manually though, I was to anxious to wait.
The 1.7 power up was to get the APIM to build 21146 for 21 builds. The 1.6 was a gateway update. I cant say what the prior one was. I believe it was a TCU(Telematic Module) update to improve responsiveness.
There are several updates available for early 21 builds that are dealer visit required. I would suggest to those of you that have not gone to a dealer or have FDRS access to log in and get all of those done and I believe that will help with those of you not receiving OTA. I am receiving OTAs and my truck is so far from stock its hilarious when I get in and see a successful update.
One Note to those with a APIM build previous to 21146. 21146 will not even show in FDRS until the Gateway update is completed, If you have a truck that has not received any updates I would suggest strongly you be the ones to go get your truck fully updated. A lot of the updates depend upon other updates being there.
Sorry if this is a bit of a rambling post, I just got on and am going freestyle. I am trying to help as best I can. I know it can be frustrating to not have updates others are getting but I really suggest you follow the advice I gave to get the updates done. I think once you do that you'll be ready to start receiving updates.
Also be careful when comparing to 21.5 trucks for as build date. They are different and some do not have the start stop they removed it so they can ship them faster.
Side note any of those with a July build that can not activate Fordpass you need to go to the dealer for a gateway reconfigure. There is a TSB/SSM/GSM about it.
B) what you're describing really feels like why the older trucks aren't getting bluecruise. They shipped them with APIMs that can't do it, and they're struggling to get OTA updates to work on the older APIMs....
