As long as it doesn't delete the Ford Performance tune or an aftermarket tune I will accept.

 

[Trimjb]

Not sure.
I don't have any of that.

I got that too, and now Gemini wants to take over for Android Auto and it SUCKS.

Go to your phone, go into setting and set the Google Assistant as your interface instead of Gemini. I had that update about a week or so ago, suddenly had Gemini running, looked up the issue and made the settings change.

I don't use Gemini. I'll have to keep an eye on it.

Thanks! It wasn't easy to find but I got it. Appreciate the help!

Has anyone confirmed if these over the air updates wipe any custom setting changes made through FORScan or wipe the ProCal tune?

 

[CACTUSGREYFX4]

I got mine the other day too for some reason it turned on the check back seat for passengers. Had to turn it back off.

 

[Mgrmax]

How would I check if it erased the ProCal tune?

Read last paragraph - TCU updates

Over-the-air (OTA) updates, including those designated for central computers (similar to ECG2-25.2.8.5), have a risk of overwriting Ford Performance ProCal4 calibrations on Ford vehicles. While Ford may state updates are unlikely to affect tunes, reports indicate OTA updates can overwrite performance tunes, requiring a re-flash of the calibration.
Key Considerations for Ford Ranger with Performance Calibration:

• Update Risk: Performance tune files (ECG2/ProCal) might be overwritten by "Central Computer" or "ECG" update types.
• Best Practice: It is highly recommended to turn off automatic OTA updates in your vehicle settings to prevent unauthorized overwrites. This allows you to manage updates and consult with Ford Performance or your tuner first.
• Re-flashing: If your tune is overwritten, you will likely need to re-flash the PCM using your ProCal4 tool to restore the performance calibration.
• TCU Updates: Updates specific to the TCU (Telematics Control Unit) often relate to connectivity and generally pose less risk to engine calibration compared to ECG/PCM updates. However, many OTA updates are bundled, so reviewing the update details in the Ford app is important.

Disclaimer: Based on user experiences with similar "Central Computer" OTA updates (e.g., ECG2-25.2.8.5) and performance tunes.

I received the update also and for some unknown reason it screws up one of my SiriusXM channels every time.

 

[superj]

no ota update has changed my procal tune or any changes i have done in forscan.

i thought it did one time but i just hadn't used a certain app in so long it wasn't in the normal view area anymore. i found it though and it still worked. (youtube app, hardly use it since i am always driving)

 

[Sparky62]

I received my update today, hopefully nothing gets fubar'd.

 

[Trimjb]

I don't know if this is from the update but now when I receive a text and do read aloud I am now getting a guys voice. It use to be female.
Screen is different too.
Could be possible the person used a voice text?
