Installing Comma.ai / OpenPilot (BlueCruise alternative)

[ScoobyDoo27]

First, I want to thank everyone who has made this community an awesome experience to be a part of. There has been an amazing amount of collaboration and positive feedback for the entire BluePilot team. As we reach the two-year anniversary of the launch for BluePilot, I am taking a moment to let the community know that I am shifting my priorities now that BluePilot 6.0 has been released. I never had a desire to lead my own fork; the whole project started because I was passionate about improving how openpilot behaved on Ford vehicles. After I developed several key improvements, but my PRs were rejected or ignored by Comma and the popular forks, and since I felt guilty about how much better my experience was than everyone else driving a Ford, I started BluePilot. While I have learned a lot from leading this project, it is not the type of activity that I enjoy. The grind of keeping up with the changes forced on forks from Comma has left me with no time to pursue the aspects of the project I do enjoy. I have been unable to make any progress on better lateral control, firmware unlocks (I bought a spare PSCM over a year ago and have not had an opportunity to work with it), and new vehicle ports (Big Bronco anyone?). Now that bluepilot is in a very stable state, I will shift my focus back to the efforts I believe will have a greater long-term impact on the community. My reduced online presence will require other members of the community who have benefited from the last two years of work to give back by helping new users get started in the ecosystem. @tonesto7 will be continuing to support the project, ensuring the platform can remain current by incorporating upstream changes and supporting compatibility going forward. I am also seeking individuals who would be willing to take on a role of interfacing with the community for bluepilot, soliciting feedback on new and future features, testing, and developing the future branches. If you are interested in taking up this mantle, please reach out to me via a direct message.

I appreciate all your effort you've put into BluePilot, it has made my commute to and from work so much better. You've always been friendly and helpful when I've had questions or needed help. Thanks again and best of luck on your future projects.

Thanks for BluePilot! I really like using it, and you have been most helpful! I am familiar with how a labor of love can turn into a thankless job and a time suck, so no argument on my part! And thanks for finding people to carry the torch!

I was trying to search through this entire thread before asking but was unsuccessful in my answer. If it’s in here, I apologize in advance.

When upgrading from 3X to 4, can I reuse the same harness? Do I need to plug in the OBD or can I get power without it?

You can reuse all of the harness and wiring just like the 3X.

Thanks!

Right now I have OBD connected for my 3x, would I will that for the C4? I’m trying to steer away from using the OBD if possible.

It's optional. The device will power on and off with the car without it.

I have just installed my Comma.ai 4 today. Are we limited on steering angle and input as it seems to have issues with curves that are not gentle. I also am using the default BluePilot install.

yes. Comma safety limits are absurdly conservative. Even without them cord designed the system for interstates, not urban roads.

I would recommend you read all the articles. It will take less than 45 minutes and answer a thousands questions.
