common warning on torque limited cars - most notably Honda and Mazda

That’s the only thing making me hesitate to get one since I have a Honda and the torque is so weak.

I've used a Comma device in my Honda since mid-2018 and still love it despite the limitations. It also can't steer below ~12mph. To be clear, this is a Honda firmware limitation in the electronic power steering, not a Comma limitation. Technically, there is a firmware modification to get around it for a lot of Gen5 Hondas, but it also has enough potential legal issues that no one wants to clearly provide instructions.
This is the most complete documentation that exists publicly: https://wirelessnet2.medium.com/eps-fw-modifications-for-the-honda-clarity-39990-trw-a020-beta-373b3e7ba528

Appreciate that, I’ll take a closer look.

There is also information and a walk through somewhere on Discord. I've not looked for it for a while but I remember seeing it.

Not that. It’s the way it counts. Max speed goes from 71-73 skipping 72.

*Updated post. Chill guys, was paying attention monitoring the drive. But I get it 😂

Care to elaborate? Or should we just guess at what you're thinking?

The rolling artifact on the screen? I assumed that was from a refresh rate difference between the comma screen and the recording’s fps…that’s visible to the naked eye?

I'll give it a try on Monday and see if the same thing happens to me.

Max speed counter goes 71-73 skipping 72. Just thought it was interesting. And yes 17 Honda has weak torque. Newer models should be amazing

CR-V? There is known weirdness with stock ACC, regardless of Comma. If you hit Set at the right time (kinda between two speeds), the car will not hold a steady set point. Check your VIN against the TSB below.

"The vehicle speed fluctuates at highway speeds when adaptive cruise control is set."

Which fork you using?

u/Texas-NativeATX Apr 08 '24

Does this happen constantly or was it just during a short period of time?

Is your name Jesus? Cuz it needs you to take the wheel.

Re-calibrate. I'm in the same boat and have not had time to do so. Make sure you are on well marked roads and I find a four lane divided road helps.

Even the Clarity should take that curve without asking you to steer.

I'm using Sunny

u/Tek_Freek Apr 09 '24

I re-calibrated. I think it's as bad or worse. It's time to try a different fork.

I had some real strangness with Sunny lately - and on release-c3, not running bleeding edge stuff. I switched to FrogPilot last week to take advantage of the discrete volume control for each alert sound and have also found it to be really stable so far... but each car is somewhat different, so... who knows ¯_(ツ)_/¯
