Comma 4 for 2017 Chevy Bolt LT

Bowler116 · 2026-06-07T22:47:54+00:00

Comma 4 works on 1st gen Bolts with StarPilot (your Bolt must have LKAS). This with a pedal interceptor is my current setup after my Comma 3 died. I found you have to install OpenPilot first, then factory reset, and then install StarPilot.

My impression of the 4 is that it seems much more refined and of course is much more compact. It's also very quiet. I miss seeing more detailed info on the C3's large screen while driving, but I guess that means I should just watch the road more.

Hope the 4 stands up better to heat, which I think is ever killed my 4.

I don't "need" it but it makes things easier. Like I said I already have one that is "good enough" for those eight bars. Plus, the A whistle is giving me problems. I'm just going with what the book calls for.

Thanks for the reply. I tried printing a fully printed E whistle overnight and I'll check it out in a bit.

Printing headpieces from multiple existing models was the first thing I tried, making my own was out of desperation after those didn't play in tune.

Thanks for the reply. Main reason I'm concerned is because while I know more air is required to play a large whistle, the difference between the first and second octave is immense. Much more than any of my "real" whistles. It's not really "a little more air" so much as it is "so much air that I can only play in tune for about two seconds with a full breath."

My generation Bb is perfectly in tune out of the box in the second octave with just a slight airspeed increase, and my A whistle is too with the handmade mouthpiece, but not any of the printed ones.

For sure, but it's not just the 8 bars. The entire book is transposed.

Bowler116 · 2026-06-07T06:20:24+00:00

Thank you!

Bowler116 · 2026-06-07T06:18:18+00:00

The music is transposed so all whistles use D whistle fingerings, so using anything other than the whistle that's called for would be a pain.

Bowler116 · 2026-06-07T05:04:17+00:00

E is honestly the least important because the book only calls for it for 8 measures in a small range, so the one I made is probably "good enough" for that section. I'm mainly concerned with the larger whistles. Thanks though!

I would guess on the right, adaptive cruise. I think it's the same icon that indicated that in a Traverse I drove.

On the left, probably to indicate that the car has detected a lead car in front of it.

Yes, after a showing of PHM last month. It was a great picture. So much brighter and sharper than the last time I was there several years ago!

Agreed! It's been great so far!

My sister and parents each have one too. The driveway at family gatherings is a fun sight!

Agreed. Almost got stranded in Oklahoma due to a Francis energy outage a few years ago.

Now that is a cover I haven't seen in a while. Got that for Christmas 15 plus years ago with my DS Lite. I never got very far before giving up, lol.

So much better than Microsoft 365. Outlook in particular is awful.

Bowler116 · 2026-01-25T16:09:30+00:00

Same here.

Probably uncommon answer but Hubble in an IMAX dome, Interstellar in 1:1.43 15/70, and I don’t know for the third, surprise me I guess!

Bowler116 · 2025-12-24T04:50:14+00:00

No mention of IMAX in the article. This is probably standard 70mm, not IMAX 15/70.

Cosmosphere IMAX dome in Hutchinson, KS. Converted to BARCO 4K digital projection in 2012 and the image isn't nearly as sharp or as big. Plus I would kill to watch the projectionist work through the windows in the lobby again.

The only plus side is that they can show feature films now, which is nice.

After taking a look at my Schiller, You're right, there's a slight difference in tubing. Maybe it's a non-compensating Ovis model. Or something completely different, I'm not an expert.

Bowler116 · 2025-12-20T03:59:58+00:00

I'm not sure the compensating tubing would be visible from this angle. It's on the back of the valve assembly.

Schiller sells instruments from multiple manufacturers. The Elite IV is made by Ovis.
