Just installed a new Comma 4 on a 2025 Lightning Lariat (have the BluePilot noise coupler in there). Vehicle is throwing no errors or codes; everything appears fine. Comma is connected to Wifi and has Bluepilot installed (bp-c4-basic). Sunnylink is paired/setup and displays the Comma status on my phone just fine.
But: Comma says "start car to start using SunnyPilot". My car is started. I drove around for ~15 minutes, no change. I turned it on and off/again, and drove another 10 minutes. I set the Vehicle in SunnyPilot to "Ford F-150 Lightning 2022-2023". (Maybe this was a mistake?)
Not too sure what to do next. Any help appreciated.
Thanks!

It's my understanding that the 2025 Ford EVs use an encrypted data buse and aren't compatible with Comma AI. There are a number of threads and the Comma forum that reference it.

It is likely one of your cables isn’t seated fully. Try rotating the connections on both ends of the long USB C cable 180 degrees and make sure they are plugged in all the way.

Sorry, I have followed this closely before ordering one for my 2022. If you do a Google search you will see Ford has begun encrypting some 2024-25 models and that people are reporting problems with comma AI on newer model Lightnings. ALSO, if you check Comma AI's compatibility list doesn't showF150s after 2023 models.

No lightning shows as compatible on commas site either. ICE F-150s are encrypted with tron as are most of their recent vehicles. But that doesn’t change the fact that the lightings are not encrypted. Feel free to read through this thread to see multiple users with a 2025 with the comma installed.

Thanks! That worked (2025 F150 Lightning). Rotated a few connections around, nothing changed. Then I rotated the small USB-C to USB-C extender in the Comma4 sliding dock, and that did the trick! Just did a calibration drive.
Different topic - the Comma was abandoning turns all the time; beep beep beep then tell me to take over, throwing the car into the other lane. Is that typical? "Turn Exceeds Steering Limit." Is there some F150 setting or branch that fixes these tolerances and is customized for the steer torque?
Is Comma only safe on straight stretches with extremely mild turns like highways? Fine if that's the way it is, as it is likely still better than BlueCruise, but I'm curious to know the limits. I was very surprised at how often it abandoned turns.

Comma has absurdly low safety limits. It will handle almost all highway driving, but surface streets will be hit or miss.
if you are running bluepilot then the torque bar at the bottom should show you how close to you are to the current limits.

2025 here and runs great on bluepilot, as far as sunnypilot goes is the lightning supported now? May need to SSH in and add your own fingerprint. I know with Bluepilot the 2025 fingerprint wasn't there so I added it manually.

You can still force your fingerprint manually, but on the C4 it has to be done from the sunnlylink website, no ability to do it locally on device.
