Comma 4

I’ve tried 5 different models and they all did the same thing. Some way worse than others. So far, my current model is easily the best, but still not perfect. Guess I need to try a few more models.

Okay, okay. Now, I’m getting pretty excited about shelling out some more cash for this upgrade 🫤 Hey, it’s only money, right ✌️ I do have one question. I have found that the North Nevada model is clearly the best I have experienced for longer sweeping curves. However, even that model can...

I’m in the mountains a lot. I almost always use MADDS mode in those situations. Hard to tell exactly how tight those corners were in your video, but the Comma definitely appeared to be performing better than I would have expected, considering the higher speeds you were going 👍

Do it! I’ve had my Comma 4 for about two months, now. I wasn’t sure what I was getting into or if it would be worth it, but what the heck. Well, I think I can now say it has been a game changer. I can’t seem to go anywhere without using it. Sometimes, I think I will just try driving myself...

Any updates on the Lukas angle based steering upgrade, when it will be available?

Go with the LT’s, if you go off road, at all. For the record, I now have about 4000 miles on my Bridgestone Dueler A/T Ascents LT275/65-20. They are still very quiet and I have experienced no efficiency hit versus the OEM PirellIs. I run them at about 55 PSI. Noticed a little stiffer ride, at...

For the record, I had to have my SC do an alignment on my ‘23 R1T. It was also $287.

Intriguing product. I’ve always wondered if/when somebody would come up with this. I only wish that Rivian had offered a solid roof as an option. I would have been all over that. If my current roof does break, this carbon fiber roof may be a perfect replacement.

I have the Comma 4, without the Xnor longitudinal upgrade. I haven’t felt the need for that upgrade. But, this new angle steering deal has me very interested. I drive regularly on curvy mountain highways/roads. My stock setup definitely has limitations in this environment. The Xnor angle...

I installed the original release last week. I received a notice to install the updated version a couple of days ago. I have yet to do it, however. When I get in the truck, I actually get a notification to install it. My iPhone app is also showing that I have an update to install.

I understand they differ. I‘ve just lost a little confidence in the last two updates. With the recent Unreal Engine implementation, their UI seems to have gotten worse. Now, we’re seeing a rash of other issues popping up. Just sayin’.

I, also, just received the notification about the 2026.07.0 update that I already received and updated last week, when it first came out. Now, I’m wondering if I should give it a second download/install or leave well enough alone and stick with what I have. This is kinda weird. I think I’ll wait...

Thank you, again! That fixed it. It was driving me crazy.

Well, here’s a new one. I got in my truck, today, went to activate my Comma 4, and the Comma display said “SunnyPilot unavailable”. What’s the deal with that? I tried disconnecting it from the mount and reconnecting it, but that didn’t do anything. I even did a software reset on the Rivian. That...

This is all swell. Usually, it takes a few days before my number comes up for any access to a software update. This time, I think I was in the very first batch - woo-hoo, lucky me. I’m afraid I made the mistake of jumping right in with this sketchy update. Then, the bugs show up and it gets...

My elevation stats were wiped out, as well. Haven’t tried a reboot.

This being my first EV, my aha moment came when I realized the whole refuel protocol was totally different from that used with an ICEV. Instead of always filling up at each refuel stop (who doesn’t fill their ICEV to the brim at each stop), with the EV you just need to put in what you need to...

Wonder why they changed them in the first place. They were just fine prior to the last update.
