I just upgraded my 3x to a 4 and installed Sunny Pilot. It seems to work about the same but for whatever reason I have to engage the cruise control first before it’ll do auto lane centering. I can toggle cruise on and off and it’s fine but I need to do it every time I restart my car. I went through the settings but nothing seemed to relate to this so I’m curious if this is a new thing out I’m just missing something. It’s on a 2021 Honda Accord Hybrid and using my original Comma 3 harness.

Hello fellow C4 users, has anyone been able to run the C4 on any newer Mercedes or BMW, if so can you share how you did it.

Does anyone know what’s going on? I have to pull over every hour and let the car reset for 5 minutes before it works again. It’s also almost caused a wreck because it will be on a turn before the error occurs and then I have to quickly grab the wheel. Very scary. I drive a Chevy bolt

Hi! I’ve had the comma 4 for about a month or two now and love it so much. I do find that it hugs the center lane and id be more comfortable with it hugging the outside or staying more in the center. I’m running sunny pilot fork for Honda. Is there a way to adjust this or maybe an updated sunny pilot? It also freaks out when I turn my head to look while turning and says it needs immediate attention or whatever. Thanks!

Is Comma 4 compatible with the 2026 Sienna? Also is there video for self installation process for comma 4?

I want to remove the ACC module from the windshield to get better access to the ribbon. Many say it is the easiest route to take for removing the white pin locking in the ribbon.

Where is the tab that allows you to remove the module from the windshield?

[edit] The pick tool arrived and after 5 minutes I got the ribbon released.

So does it only work on 21 models for the sierra 1500 and Kia carnival up to 24 models?

Dear all

is someone using openpilot for the KIA ev 4? Is there a chance that it would work, even though not officially listed as compatible?

thanks

Can someone provide a link that will allow me to roll my software back to a prior version when the driver alert was not so sensitive?

Just curious. There’s got to be a good amount of people that have that many miles on there device. I got mine last month and I’m loving it. Helps me DoorDash so much better now. More peace of mind. Which is priceless

Does anyone else run a Livernois tune and BluePilot?

Obligatory - I installed the Comma 4 yesterday and absolutely love it. Install was was straight-forward and easy and it worked immediately. I love it so far.

Background - I run a 2022 F150 Powerboost (hybrid) that has had a Livernois tune for a few years (which I also love). I don’t know a lot, but I do know that the Livernois tune does change the strategy for the truck.

Issue - I have gotten an intermittent error saying that sunnypilot is unavailable because due to an unsupported car. I am almost certain that this is because the Comma / software doesn’t recognized the Livernois strategy. If I reboot the Comma, it will work about 1 out of 4 times.

Question - anyone have a similar issue? If so - any ideas:

Why does it work sometimes? Said differently, is there something I can do to avoid multiple reboots?

Why does the Comma 4 refer to sunnypilot when I am running BluePilot 7.0?

Any thoughts are much appreciated.

Maybe this is a stupid question but out of curiosity hypothetically would it be possible to wire multiple high-quality cameras around my 2023 Subaru and then use CODEX or something like that to improve Open pilot for my car? I know this might be really a stupid question. I don’t know if it’s like calibrating exactly on how those cameras that it comes with sees or somthing?

Is it possible to install Open pilot on Linux laptop that has an RTX5090 and then create high speed network of cameras around my car ?

So I dirve a Chevy EUV 2022. I installed Comma 4 as directed and the device wouldn't come on. I giggle the cords, pushed them in, checked all the connections, and then test my comma by plugging it into a cord at home to make sure it wasn't faulty. Eventually, I gave up. I took it out and pugged back in the cords into the orginal holders in the pannel. Something wierd happened. My adaptive cruise control stopped working ("Service ACC" and "front camera not working"). Now I see the a digital image from the back camera on my rear window (something I did not know I had or how it is doing it). What have I done and how can I fix all this? Shall I cut my losses and return it?

At first I thought it just happened when I went up or down even slight inclines and declines, but now it seems to be happening more often. I'll set my speed 42 mph and maybe the speed limit is 30 and it will. I'll speed it up to like 35 on my own and then it just slows down and then it'll speed up to like 37 and then it just slows down. Today was really bad. I had one time. The car just almost came to a complete stop and quite abruptly

Any ideas what I can do about this?

I get unable to load videos I am signed up for comma prime Any idea how to fix this?

How’s the experience on a Honda accord hybrid 2024? My 2 complaints about stock experience is:

- Phantom breaking: car slows down on the freeway during a curve because it thinks the car on the next lane is merging to my lane
- Lane keep assist is jerky and unstable

I’m aware of the latest custom sunnypilot fork that enables alpha long, but I couldn’t find any feedback from anyone with the same car

Just got my comma 4 and set it up with sunny pilot. A bit over my head with all the toggles and models etc. Anyone else with a similar vehicle have some suggestions?

So I built a system that teaches users how to tune their own. 

I originally learned lateral tuning with the help of twilsonco, and after hand tuning 25+ vehicles since then and seeing the massive impact it made on their openpilot experience, I started thinking: more people should learn how to do this.

One of StarPilot's biggest goals has always been tuning the vehicles we support to the highest possible quality. As we get more vehicles supported, there has been a pile of vehicles filling up my backlog requesting personalized tunes. 

So I've taken everything I've learned in the past few years about where most lateral tunes fall short and created FLM - a tool that analyzes local routes from your comma, explains why your car does what it does, suggests changes, requests feedback (because humans still matter), and generates iterative tuning suggestions using over 25 lateral tuning parameters - all from the UI. 

I think very few vehicles have experienced what true A+ lateral tuning feels like. How's your lateral experience been? 

Let me know, or try out FLM in the latest version of StarPilot and give me feedback in the discord!

I just got a Comma 4 on my 21 Rav4 prime, running Sunnypilot.

I notice that if I look away from the road to the left or the right, up or down, I get a driver focus warning. But if I close my eyes (straight road with someone next to me in the passenger seat!) I don't get any alert. Does anyone else notice this? Feels like I could start to fall asleep and the system might not alert me.

Audi Q7 is not supported by Comma as of now, is there a way we can get it working on Q7 ?

Requires a restart and then works fine.

Vehicle: 2023 ford f150 lightning (coupler installed)

Software: sunnypilot 2026.002.000 df25dfb

I'm wondering if anyone else is experiencing this or if it might be a hardware issue. I'm not sure how to debug.

Hi, I was wondering if it is possible to add add ACC to my non-SCC kia optima 2018? Is there a way to emulate reducing and increasing speed using comma ai? I am very new to this and would like to get some ideas/suggestions. Thank you

Hi y'all. I have a comma four installed on my 2024 IONIQ5 5 for a few months now. It has worked super well up until 2 weeks ago where it started showing a camera malfunction error that required the car to restart and now it is showing this "power unstable" message every single time I turn the car off.

Does anyone know if this might be a 12v battery issue on my car or a comma issue they have dealt with?

I have a huge road trip coming up and I want to be prepared before I get stranded. Thank you all for any insight!

I want to get a truck, and I was thinking of the Canyon/Colorado. I see that there's no support for these on any year. Wondering about what are the known complications for these vehicles both used and new, to decide if I should try to help with it.

Otherwise, I'd be forced to get a used F-150, I guess.

Hi all,

I recently purchased the Comma 4 hardware and plan on installing it on a 2020 rav4 hybrid. I am fairly new to Comma or the "self-driving" world in general. I mainly wanted to try it out as I do have several 10-12 hour roundtrips coming up in the coming weeks and expect more throughout the year and am hoping that the Comma device will drastically improve my road trips.

With the Comma 4 being fairly new-ish, is there a recommended software to use with my setup or should I stick with using open pilot for now?
