Comma AI Owner Demo Drive Connect Thread

[Viet658]

I’m in Pomona, CA with an 3X and would be happy to give demo drives. Love the comma but I’m in the same camp as others who prefer the gap distance of Rivian ACC

I find for our traffic patterns here that I prefer sunnypilot mads mode over cruise regardless of op long or Rivian acc.

Late to the party, as usual, but I'm in Vancouver, WA, and am happy to offer demo drives.

When did you place your Comma order? I’m 3+ weeks into my order and wondering when I should expect delivery. Also, on the Lucas harness, what was the final cost and delivery time on that? I have a Janka mount showing up tomorrow. Ordered it on 2/6. So, pretty quick delivery from China. Thanks.

You can find spreadsheet on their discord with estimated ship times.
I placed order last week, and my eta was 7 weeks at the time.

Thx for this link!! I was able to open it and it definitely answers my delivery question, or, at least, narrows it down. It’s looking like the first week in March, for me. For some reason, after many tries, I have been unable to log on to the Discord site. I have pretty much given up on it.

Ok, i just finished installing my comma 4. I used the luka longitudinal upgrade and a slide mount. I have the fuse tap connected in F33 and i exchanged the 20 amp in jankas fuse tap with the 10amp i pulled out of f33. I installed the cross glide mount, and i am using the janka hub box in the footwell to connect everything to so i only have one usbc cord running up the A pillar. I turn on the comma and it downloaded sunnypilot no problem. It had me drive for a short time while it calibrated. But when i tried to engage the comma it does nothing. Thoughts? Help? Also, there is an red triangle with an exclamation point on the driver display in lower left corner.

False alarm, i did a hard reset (held down far left steering button and hazard and it cleared the error. It is working now and its beautiful!

I get my Comma 4, tomorrow. Let the games begin Hope all goes well. I think I will have your same setup, minus the longitudinal upgrade. May get that later. We’ll see.

You'll like your Comma and want to see what else it can do so you will get Lukas' Longitudinal upgrade kit as well as the Chun or Janka mounts for easy dismount from your windshield so it doesn't bake in the sun this summer. I've had my 3x since May and love using it all the time. With the upgrade kit, it taps into the sensors for blind spot monitoring during auto lane changes. Try the stock Comma and when you do get the upgrade kit, you'll be asking yourself why you didn't get it sooner.

Guys, how do you download the version of sunnypilot that allows auto lane changes? Gerry, i tried using the branch that you installed in the “DIY Rivian autopilot” video but it wouldnt install (sunnypilot/staging-c3-new). I’ve downloaded the version i found on their sunnypilot website (staging.sunnypilot.ai) and that downloaded and works but it doesnt have a lot of the options that you were using in that video, including auto lane changes.
