Configure Toggles & Settings

Toggles

Most toggles here are up to you.

ACC Bolts Only

Enable "openpilot Longitudinal Control (alpha)". This will use the smoother, tuned experience vs. the Bolt’s stock ACC. It does not disable automatic emergency braking.

FrogPilot Settings

In general, FrogPilot settings should remain between fork installs and branch switches.

TL;DR?

Just look for all the blue highlights - they will tell you any settings you need to turn off or on for best experience.

Tuning Level

There are multiple tuning levels in the FrogPilot settings - these will enable or disable more advanced tuning parameters.

For best results on StarPilot, you’ll need to use the Advanced tuning level.

Make Sure your Fingerprint is Correct

If you ignore the rest of our suggestions here, at the very least, make sure you set your correct fingerprint to avoid issues.

Alerts and Sounds

These are optional changes. Some popular changes include:

  • Under Alert Volume Control, you can adjust or mute the disengage and engage sounds. We DON’T recommend changing the volume of any important alerts.
  • Under FrogPilot Alerts, you can enable the Green Light Alert and Lead Departing Alert to get gentle nudges when a traffic light has turned green or the car in front of you has started moving.

Driving Controls

Driving Model

  • Automatically download and update models: Turn On

Warning

This is a departure from previous advice - we used to advise against this due to the potential for incomplete models. But with the new tinygrad model switcher, having this on helps ensure all pieces of the model have been downloaded correctly.

Full info on models coming soon. For now, try the following:

  • WD-40: A smooth, but outdated experience. It'll be like 75% good for lateral and longitudinal control.
  • LeTR: Our current go to tinygrad model. Try this first! (as of 7/20/25)
  • Vikander: A custom model by the venerable chubbs. Great long, decent lat. Some users experience bad oscillations, but it varies by environment, so try it out!
  • TR Models "Tomb Raider" models. There's always a new version, TRX is decent, higher numbers can be VERY hit or miss. Use with caution.
  • Simple Plan (SP): Seems to be decent, some minor oscillations but better than Vikander. Most have switched over to LeTR.

Gas / Brake

Conditional Experimental Mode: Turn On

These settings control Conditional Experimental Mode, often called "CEM". Experimental Mode (vs "Chill Mode") is not yet good enough to handle all driving. But it can handle traffic lights & stop signs, and is better in some situations. So we automatically enable it in certain conditions where it is better than Chill.

Experimental Mode has a tendency to slow down/speed up weirdly, and overall just behave strangely, so we recommend conditionally enabling it only when necessary.

  • Curve Detected Ahead: Can be useful if you regularly take tight corners above the speed limit. Activates when a tight curve is detected. Most leave this off. Likely to be superseded by a fancy new curve speed control FrogsGoMoo is working on.
  • Lead Detected Ahead: Turn on both Slower Lead and Stopped Lead, to help the model better slow when using VOACC (Visual Only ACC).
  • Navigation Data: Recommend leaving off.
  • openpilot Wants to Stop In: Helps with slowing to a stop at lights, in traffic, etc. Default is 8 seconds. Increase this number if your car is not slowing down in time for leads/lights. Decrease this number if you're getting lots of false activations and the car is going in and out of CEM when it shouldn't.
  • Status Widget: Up to you. Recommend leaving on. Shows an icon that displays if CEM is active, and if so, why.

Curve Speed Control: Personal Preference

Relatively privative currently. Slows down for curves. Advanced CSC coming soon.

Customize Driving Personalities: Personal Preference

Allows you to enable or disable certain personalities.

Manage lets you set the follow distance to your preference.

These have been tuned by firestar - if you wish to tune how they react, you can unlock additional settings by switching to the developer tuning level. Be careful though!

See Appearance -> Driving Screen Widgets to enable an on screen button for switching personalities.

Optional: A macropad accessory is available to adjust driving personality without touching the screen. It costs around $25 and requires minor tinkering.

Longitudinal Tuning: Turn On

  • Acceleration Profile: Sport
  • Deceleration Profile: Eco

The above profiles have been specially tuned to work better with the Bolt's accel & decel curve.

  • Human Like Accel/Leads: These do... things? This will change how the model acts. Sometimes quite significantly. Varies model to model. Test with on and off.
  • Taco Bell Run: Just leave taco bell run stuff off.

Hate a model?

Model trying to drive you into the back of leads? Model leaving a gap of 200 certified football fields? Try turning on or off the "Human Like" settings - they often change quite a bit about a model's behavior.

Quality of Life: Turn On

  • Cruise Intervals: These are up to you! I'm not sure the "long press" works on all vehicles. Some like to increase short press to 5mph for easier jumps in cruise speed.
  • Force Keep openpilot in the Standstill State: When this toggle is on, openpilot will require user input before it will resuem from a fully stopped state.
  • Force Stop for "Detected" Stop Lights/Signs: Recommend Turning On. This will help prevent (but not eliminate!) the Comma from running red lights or stop signs.

Stop Light and Stop Sign Detection can be Inconsistent

You should always be extremely alert and ready to take manual control at stop lights and stop signs. Every model is different, and although red light and stopped lead detection is getting very good, stop sign detection is still quite bad. Additionally, our reliance on regen-braking only in the Bolt means that openpilot will often not have enough stopping power to stop in time once it has detected a stopped lead or traffic light.

  • Increase Stopped Distance: Only applies when coming to a complete stop. If your car is regularly stopping too late when coming to a complete stop, increase this number to your preference. This will not help in cases where openpilot did not start slowing in time. See "openpilot Wants to Stop In" in the CEM settings for help with this.

  • Map Accell/Decel to Gears: Allows sport mode to increase to the next accel profile. Reccomended to keep off as sport mode changes the lateral response for gen2 cars (gives them less torque).

Steering

Advanced Lateral Tuning: Leave Off

Section is WIP, features here are more for special cases & testing.

Always on Lateral: Recommend Turning On

Always on Lateral, also known as AoL (or mads in sunnypilot) allows you to turn on just the steering control (lateral) without the pedal control (longitudinal). This can be quite nice & useful, so we generally reccomend having it on.

With this on & the default settings, the cruise control main button (the one that turns all of cruise control on or off) will enable/disable Lateral control. Then, with cc main (and therefore AoL) on, hitting set or resume will enable longitudinal control. Cancelling with paddle or brake will keep AoL enabled but turn off longitudinal control.

Does not work under 6mph

The Bolt does not allow for lateral control under 6mph. This applies to AoL and standard modes. It will not steer for you under 6mph.

Lane Changes: Turn On

  • Automatic Lane Changes: Turn Off. With this off, you have to nudge the steering wheel before it changes lanes. This is ideal, since it lets you signal to other cars that you are changing lanes without actually starting the lane change.
    • Due to a quirk with steering torque, human-initiated lane changes will also be smoother and more natural.

Stay Aware while Changing Lanes

The Comma won't change lanes if it detects a car in your blind spot, but you should ALWAYS check first. Neither your Bolt's blind spot monitors nor the Comma have 360 degree awareness.

  • One Lane Change Per Signal Turn On just to be safe.

The remaining settings can be left at default.

Lateral Tuning: Turn On

  • Force Turn Desires: Leave off
  • Smooth Curve Handling: Turn On

If NNFF appears here, disable it. Upstream NNFF doesn't play well with the different gens of Bolt.

Quality of Life Improvements: Optional

Ignore Navigation. It's not supported very well by Comma and it's a pain to set up. It's not able to, say, drive you to your destination without your intervention. Just use your prefferred mapping app via CarPlay/Android Auto.

System Management

Optional. Provides options for adjusting the screen brightness and other device settings.

Theme and Appearance

Appearance

  • Advanced UI Controls: Optionally enable

    • Some prefer to hide Current Speed and Lead Marker for a cleaner look. I like leaving them on. Lead marker can be useful when testing new models. All personal preference.

  • Developer UI: Leave off, unless you have a specific reason to turn this on. Gives stats and things that are useful for troubleshooting & development purposes, but not useful for day-to-day driving.

  • Driving Screen Widgets: Turn On

    • Enabling Acceleration Path, Blind Spot Path, and Rotating Steering Wheel can be nice, but is optional
    • Driving Personality Button: Turn On for Gen 0 and Gen 1. In StarPilot, the driving personalities mostly handle follow distance. Gen 2 is able to control this using the steering wheel button. Gen 0 and Gen 1 need to use the on screen button for this.
    • All other options are optional.

  • Navigation Widgets: Optional

  • Quality of Life: Optional

    • Can adjust camera views, standby mode, and other optional settings

Theme

If you prefer a more professional look, you can disable all toggles here and set the startup alert to stock.

The frogpilot startup alert & various frog themed things can sometimes be concerning to passengers who have not encountered the Comma before.

  • Custom Theme: Optionally disable frog noises. Although I'm personally generally fine with the more fun frog-themed stuff, I do always change the sound pack to default to disable the frog noises on activation/deactivation, as I find them to be a bit much.

Vehicle Controls

Vehicle Settings

  1. Select your car model.
  2. Disable Automatic Fingerprint Detection.
  3. Under General Motors Toggles DO NOT enable FrogsGoMoo’s experimental longitudinal tune. DO enable Smooth Pedal Response on Hills.
Fingerprinting Info

Fingerprinting is inconsistent on GM vehicles at the moment. As such, sometimes ACC bolts decide to fingerprint as Non-ACC which causes fun issues such as… not having Gas/Brake. So to be sure, it’s just always best to manually fingerprint.
