(Ended) Comma 3x Sale for $899

[LL75]

Installed the Aug 10th sunnypilot build this morning... We have pandas... Time to start a zoo....

Sorry, have not been in the loop since Gerry helped install the comma a few weeks ago. Is this the new software?

Sunnypilot had a few updates over the past week plus a good number of new driving models were added. At one point, we lost longitudinal control because Openpilot deprecated the panda that is used for us, but Lukas and Sunny got that resolved and was merged. You may have automatically updated and not even known. You can always go to the software tab before activating the truck or in off road mode and hit the check for updates button.

Can anyone comment on how does comma 3x compare to Rivian Gen 2 autonomy platform?

I drove a gen 2 R1T yesterday and the difference was day and night. My 2023 R1S violently swings the car from one side of the lane to the other every time there is a curve in the road but this new gen 2 is very smooth. I would love to install the comma 3x if the lane assist alone is comparable to gen 2.

This comment is so far out there...

My 2023 R1S does not do any of the violent actions you describe occurring in your Rivian.

My suggestion is to open a service ticket.

As Audiotek stated, your Gen 1 shouldn't be doing that.

To answer your question, though - in my opinion the Comma 3X, especially when paired with Lukas' longitudinal upgrade and Sunnypilot with MADS, is actually superior to the Rivian Autonomy Platform exerpience as it stands today. I have no doubt that RAP will get better over time, so I may revise my answer in the future, but right now the Comma 3X offers a better experience with more features.

So, yes, I would recommend a Comma 3X, but if you have an underlying problem with your suspension or something that is causing your car to violently swing within a lane, the Comma 3X may not solve it and it should definitely be looked at by some Rivian techs.

That is very interesting, I didn't think it could be my vehicle. I assumed that's how the Rivian lane assist was. In the beginning when I started using the highway assist, every time there was even a slightly sharper curve in the road the vehicle would swing and the wife would squirm in the passenger seat so I stopped using it when the wife was in the car. Currently my R1S is in the service center for the suspension clunks on rough roads, they may replace jounce lines and/or dampers if they deem necessary. I will try to add this to the service request.

I noticed in one of your videos you made a comment about how Rivian's lane keeping is horrible and that it "ping pongs" in the lane. So I assumed that's what my R1S was doing too. Now I am thinking of at least opening a service request to get it checked out.

It can ping-pong in a lane, but I wouldn't call it violent. It's more of a slow, smooth movement from one side to the other, like it just can't decide where it wants to be. If you're experiencing violent sideways movement, that sounds dangerous and should be looked at.

Perhaps it was embellished a little, but Rivian's turning can be jarring. Comma definitely softens that out. Same with centering - D+ will float a bit and depending on the road can feel ping pongy - again, comma softens that too.

As Gerry said though - the comma with long is a notch above the current state of AP+. Over time, this may change, but there is a cost factor involved for those currently driving a gen 1 that in its current state, does not equate. The other thing to keep in mind is that at some point soon AP+ is not going to be free, so there is another cost to add to the equation - if you don't pay for AP+, you'll be back to D+ functionality. Just some things to consider.

You are correct(I may have embelished a little when I used the word "violent"), the turning is scary though especially at high speeds. In my case the vehicle over steers going from the outer lane line to the inner line and then corrects to try and center the vehicle in the lane. I don't have a point of reference to compare my vehicle against, except for the R1T I drove yesterday and that felt amazing.

On a side note, just got the news from the service center they are not going replace the dampers, just the jounce lines. Anything I can say to them to change their minds?

If the dampers aren't failing why change them? The jounce lines have been a known issue that is one of the leading causes of damper failure.

Just came back from the service center. I was told that Jounce lines were replaced and the fluid was low which was topped up. The vehicle has almost 40k miles on it and there was no leak anywhere so most likely the low fluid level was from factory. Now the questions is, wouldn't low fluid have caused damage to the dampers and other parts of the suspension that need the correct level of fluid? Also when I drive on rough bumpy roads in low speeds I clearly hear clunking/rattling(like you would hear from loose parts) type of sounds coming from suspension. Two technicians agreed they hear it too on the test drive with me. I will hear back from them again tomorrow.

What would be the signs of failing dampers?

Failing dampers you will see your vehicle sag when sitting for a period of time and most likely evidence of leakage. As for your rattles, unfortunately, some of that is actually normal - especially as your mileage gets higher. I'm at 70k and it rattles a bit - but they've checked everything just prior to 60k and all was well.

It is really sad to hear that the rattles from the suspension are "normal". We have a 14 years and 250k miles old LX570 with AHC suspension which still rides completely silent without any rattles or noises whatsoever.
