OTA update wiped tune

[Eskram]

Interesting... So far, this seems to be affecting OZ tunes. Any reports of this affecting livernois tunes as well?

I'm turning off OTA updates as a precaution anyway..

Thanks for the info everyone. I'm trying to decide what my course of action is going to be. Leave OTA's on and the Oz tune 'off ' or turn off OTA's and put the Oz tune back in. I've asked Ken Osborne if it's OK to do nothing at this point.

Oh bother.... never a dull moment with all this technology ?‍

I just checked my truck (FP/Whipple installed with their tune) and I see the 23-PU1009-SS-NS PCM update. The status says updates have been made, but also says the update failed. I disabled OTA and sent Whipple an email asking. My hope is that Roush, Whipple, and FP/Whipple know the secret PCM handshake and don't mess with the tuning......

I was told by Josh @ 5 Star to disable auto-updates, I wish there were a simple fuse we could pull or something that would permanently disable them because I've done it before (via toggle auto-updates in settings) and sure enough it was back on the other day.

Interestingly the Oz announcement mentions dis/re-connecting the battery can enable it, I suspect this is what happened and I was just lucky to have caught it.

Anyone know of a bullet-proof way to disable them that would be reversible?

Unplug your TCU?

Then this truck is cut off to the outside world for sure.

Disable the truck WiFi connection?

Disable the truck WiFi connection?

Yeah, that's the route I'm going to pursue. Some good info on this thread. Going to pull the fuse today. I'll monitor/post any negatives.

The vast majority of the OTA updates have come over the cellular connection, not wi-fi. @Snakebitten has the only bulletproof method I’ve heard of—unplug the TCU. That stops all communication with the outside world. No FordPass, no nothing.

I recently received 23-PU1009-SS-NS which updated my PCM and it overwrote my custom tune. The interesting thing is that it didn't seem to completely overwrite the custom tune file, certain changes were obviously still in place while others had reverted back to stock. What's more interesting is that I never received a notification on my Sync screen, and I had to check the Ford Pass app to verify what happened.

I'm not bothered by this at all, but I have to wonder how Ford is identifying Roush, Whipple, or Ford Performance supercharged F150s. Imagine taking your supercharged F150 on a road trip and having the PCM revert back to a stock file when you stop for gas or get to your hotel.

They have official files that reflect on fords servers.
Aftermarket tunes are the same file name modified.

So does anyone actually know what the PCM update is doing in terms of details?

I'd imagine that Ford releasing an update to critical hardware impacting components is basically an admission that your truck has been operating either suboptimally at best or poorly enough to damage itself at worst.

I don't think that helps. OTAs generally come over the cellular connection. Supposedly, enabling wifi only makes OTAs quicker, but there's not a lot of evidence at least on the forums that Ford actually uses the wifi connection even if it's available.
Furthermore, I believe that "disabling" OTAs only impacts the scheduling of an update that would require disabling the truck for a period of time. I don't think you can "disable" other updates except by disabling the cellular network connection by, for example, disconnecting the TCU, kinda like unplugging your router's internet connection at home.
I could well be wrong about that.

Pulled the modem fuse and disconnected the TCU. Before & after shots below. So far no in-dash or silent errors thrown (checking via SCT handheld).

Fuse - It's the unmarked #8. Pulled the 3-prong on #9 then used the 2-prong 5a spare located at #35 to restore #9, leaving the center socket open.

Thanks to all who've contributed this information, figured some photos would help.

Before:

After:

TCU - Located against the cab on the passenger side. Flip down seat, get a good grip on and yank the plastic push fastener. Unplug that far left cable.

After:

Just to be safe:

Now when I hit any of the connected oriented services I get a spinner then it gracefully stops trying and falls back to the previous menu.

Wait.
So every PCM update, and there have been many over the past 3 years, is an admission of........

OK, I guess you COULD put it like that. Technically anyways.

But then every patch/update on your phone, pc, router, television...... Would imply that the previous version was operating poorly enough to damage......

I personally have experienced the continuing drivability improvements of my 2022 over the course of a couple of years and several pcm updates. Especially the 10r80 shifting strategy. I would call it a refinement process.
And the benefits of OTA, is unlike previous generations of vehicles, the ones already sold and on the road are getting the refinements that the newer year model are being shipped with.

But I admit that if you are going to "jailbreak" your PCM, you do have to take into consideration the impact of further software development being delivered OTA.

Right, but why did the automatic transmissions in every other car I've ever had work perfectly from day one with no updates? Why did it take literally half a decade to get the shifting right on these 10r80s?

How did Ford do it right way back in the 90s with the ford explorer I used to have? That thing shifted perfectly towing or driving at any speed. I'm not convinced the extremely harsh shifting prior to these updates didn't cause excessive wear.
