I was wondering if there is a list of recommended settings or toggles to turn on?

So far, I'm not really impressed with the Comma 4. I have my lane offset set to +40, and my truck still hugs the center lane, sometimes even goes over it, and it drives like it's been drinking, constantly moving within the lane. Also, the speed is way off and hardly ever accurate. Not a big fan so far, and I hesitate to use it.

Well, a +0.4 on offset would cause it to ping pong like crazy. I've repeatedly explained that this setting should be only used as a last resort, because you are fighting the model when you try to adjust the offset. usually 0.05 or 0.1 is okay, but getting higher than that will cause problems.

If you don't like where it is positioned in the lane, verify that your device is properly centered in your windshield. Then you can try different models, as some tend to place you differently within the lane.

The Comma4 doesn't show your speed by default. There is a blue plot specific feature that placed information in the bottom right corner of the screen, and it is adjustable to what it shows. I suspect you have it set to show the speed of the vehicle in front of you.

Thanks, I will change the offset to .05 and see but I know it's going to hug the center lane. The unit is centered but I will confirm this.

What is “the Model”, why does it change so often, and why can’t we fix problem x/y/z on Fords?



In Sunnylink you can change the model, I use suggest WD40 or Notre Dame, locate under legacy models:

Okay, mine was set to the default option. I changed it to the one you are using. I'll test and see.

I changed it to the Notre Dame model and the lane positioning is much better but the speed control is awful. It doesn't maintain the speed set even when the car in front is way ahead. I will try the other model to see how that works.

not a model issue.

I assume you are using alpha long and experimental mode.

my first advice would be to turn off experimental control. What are you really getting from it? Stop signs and red lights don't work very well, so all you are getting are the headaches of it never driving fast enough because it thinks that would be unsafe.

If you insist on keeping experimental mode turned on, then toggle on "dynamic experimental control", that will help tremendously with it driving too slow.

I went down that road. My suggestion is hit the reset button so all the settings are back to default and then enjoy blue pilot.!

Alright - apparently my C4 was stuck in limbo until today. I am officially posting my 3x for sale - I don't have a ford harness anymore, but I will throw in a lightning coupler and sliding dock for $600 total (Including insured shipping) to the US. DM me here or on discord if interested. I won't be able to ship it until my c4 gets here, but it should be here by the 17th.

I bought the 3x Apr 21, 2025 - so it should even still be under warranty.

For those of you considering a C4 purchase and wondering about the 4-12 week delivery stated on Comma's website, I purchased a C4 on February 24, 2026 and received tracking info today that my C4 will arrive on March 17, 2026.

That would be exactly 3 weeks from purchase to delivery.
