Hey there, fellow Tesla enthusiast! Are you looking to unleash the raw power of your Tesla on a dynamometer, or perhaps just curious about what "Dyno Mode" entails? You've come to the right place. This guide will walk you through the process, the risks, and everything you need to know about putting your Tesla in Dyno Mode.
Understanding Tesla's "Dyno Mode"
Before we dive into the steps, it's crucial to understand what "Dyno Mode" actually is and, perhaps more importantly, what it isn't.

What is Dyno Mode?
Tesla's "Dyno Mode" is a hidden, unofficial feature primarily designed for testing purposes on a dynamometer (dyno). A dynamometer is a device that measures the force, torque, and power of an engine or motor, usually while the vehicle is stationary on rollers. When activated, Dyno Mode disables several crucial safety features of your Tesla, including:
Automatic Emergency Braking (AEB)
Traction Control
Stability Control
The primary purpose of disabling these systems is to allow for accurate power measurements on a dyno without the car's computers intervening and limiting power or correcting wheel slip.
Dyno Mode vs. Track Mode
It's important not to confuse Dyno Mode with Tesla's official Track Mode. Track Mode, available on Performance models, is designed for performance driving on a closed circuit. It optimizes the car's systems (power delivery, cooling, suspension, etc.) for track use while still maintaining a degree of safety features. Dyno Mode, on the other hand, is a more rudimentary and less safe setting that completely strips away electronic aids.
The Risks and Warnings
Seriously, pay attention to this section. Activating Dyno Mode carries significant risks and is NOT recommended for public road use.
Loss of Safety Features: As mentioned, AEB, traction control, and stability control are disabled. This means your Tesla will behave very differently, and you'll have no electronic assistance in maintaining control, especially in slippery conditions or during aggressive maneuvers.
Potential for Damage: Without traction and stability control, it's much easier to over-rev motors, put excessive strain on drivetrain components, and even cause tire damage.
Legal Implications: Driving with these safety features disabled on public roads could have serious legal repercussions if an accident occurs.
Reduced Power (Recent Changes): Tesla has reportedly limited power output when Dyno Mode is activated in newer software versions to prevent misuse and accidents. This means that if you're trying to achieve maximum power figures on a dyno, the current Dyno Mode might not allow for it. It's designed to test, not necessarily to provide full, unrestricted power for hooning.
Only activate Dyno Mode in a controlled environment, such as a professional dynamometer facility, and with extreme caution.
Tip: Focus on clarity, not speed.
Step-by-Step Guide: How to Put Your Tesla in Dyno Mode
Now that you understand the implications, here's how to activate Dyno Mode. Remember, these steps are for informational purposes and should only be performed in a safe, controlled setting.
Step 1: Prepare for Activation – Get Ready!
First things first, make sure your Tesla is in the right state to activate Dyno Mode.
Ensure Your Vehicle is Parked: The car must be in Park (P). Attempting this while driving is not possible and highly unsafe.
Touchscreen Access: You'll need access to your Tesla's central touchscreen.
Step 2: The "T" Icon Trick – The Secret Handshake
This is where the magic begins.
Locate the Tesla "T" Icon: On your Tesla's main touchscreen, look for the small Tesla "T" logo at the top center of the screen. This is typically where you find information about your car, such as the software version.
Press and Hold: Firmly press and hold the Tesla "T" icon for approximately 5 seconds. Don't let go too early!
Step 3: Entering the Access Code – The Password to Power
After holding the "T" icon, a dialogue box will appear.
"Please Enter Access Code": A prompt will pop up on your screen asking for an access code.
Type "dynotest": Carefully type the word "dynotest" into the provided field. Ensure there are no spaces and it's all lowercase.
Step 4: The Left Turn Signal & Confirmation – The Final Key
This is the last crucial step to activate Dyno Mode.
Activate Left Turn Signal: While the "Please Enter Access Code" dialogue box is still open and you've typed in "dynotest," engage your left turn signal.
Press "OK": With the left turn signal active, press the "OK" button on the dialogue box on the touchscreen.
Tip: Reading carefully reduces re-reading.
What to Expect Upon Activation:
If successful, you'll likely see a red warning icon appear at the top of your screen, possibly with a message stating that:
Automatic Emergency Braking (AEB) is disabled.
Traction control disabled.
Stability control disabled.
Dyno Mode Enabled (Dev Mode Only - Do not drive on public roads).
This is your car explicitly telling you that the safety nets are gone.
Deactivating Dyno Mode
It's just as important to know how to turn it off!
Method 1: The Simple Reset
Park the Vehicle: Put your Tesla in Park.
Exit and Lock: Get out of the car, close all doors, and let the car lock up (wait a few seconds for it to go into a sleep state).
Re-enter: When you get back in and start driving, Dyno Mode should be deactivated, and all safety features should return to their normal state.
Method 2: Re-entering the Code (Less Common, but Reported)
Some users have reported that repeating the activation process (holding the "T," typing "dynotest," engaging the left turn signal, and pressing "OK") can also deactivate it. However, the exit and lock method is generally more reliable and recommended.
FAQs: Your Burning Questions Answered
Here are 10 common questions related to Tesla's Dyno Mode:
QuickTip: Check if a section answers your question.
How to put Tesla in dyno mode?
You can put your Tesla in Dyno Mode by holding the Tesla "T" logo on the touchscreen for 5 seconds, typing "dynotest" as the access code, engaging the left turn signal, and then pressing "OK."
How to turn off Tesla dyno mode?
To turn off Tesla Dyno Mode, simply put the car in Park, exit the vehicle, let it lock up and go to sleep, then re-enter the car. This typically resets the system.
How to know if Tesla dyno mode is active?
When Tesla Dyno Mode is active, a red warning icon will usually appear at the top of your touchscreen, indicating that safety features like traction control and stability control are disabled.
How to use Tesla dyno mode safely?
Tesla Dyno Mode should only be used in a controlled environment, such as a professional dynamometer facility, and never on public roads due to the disabled safety features.
How to activate Tesla Track Mode?
Track Mode is an official Tesla feature (often on Performance models) accessed via Controls > Dynamics > Track Mode on your touchscreen, offering customizable settings for track driving.
QuickTip: Don’t just scroll — process what you see.
How to avoid damaging my Tesla in dyno mode?
To avoid damage, ensure the vehicle is properly secured on a dyno, and exercise extreme caution as all electronic stability and traction aids are disabled, making it easy to lose control or over-rev.
How to check Tesla software version?
You can check your Tesla's software version by tapping the Tesla "T" logo on the top center of your touchscreen and then looking for the "Software" section.
How to get the most out of a dyno test on a Tesla?
To get the most out of a dyno test, ensure the battery is at an optimal temperature and charge level, and consider professional guidance, especially given Tesla's power management and cooling systems.
