How to activate Tesla Dyno Mode in 3 steps for performance testing
Tesla Dyno Mode can be activated in three easy steps for owners looking to test performance of their all-electric vehicle on a dynamometer and in a controlled setting.
Tesla owner and Drag Times YouTuber Brooks Weisblat posted a video on how to turn on the Dyno Mode on a Model 3 and see how the secret mode affected the car’s performance.
Information on how to enable Model 3 Dyno Mode is also documented on a Tesla EPA filing dated October 2019. The said document details how a user can activate the Dyno Mode in three easy steps.
How to activate Tesla Dyno Mode
- Vehicle must be in Park.
- While holding down left (turn signal) stalk, press and hold the Tesla “T” logo at the top of the screen.
- Enter Dyno Mode activation password, “dynotest”.
Dyno Mode can be deactivated by the user by pressing the “Power Off” button within the Safety & Securit tab of the UI.
Once the Dyno Mode is activated the car will prompt drivers with a warning that the vehicle is on Dyno Mode and that one should not drive on public roads. With the Dyno Mode on the vehicle’s traction control is disabled, stability control is disabled, as well as automatic emergency braking.
“Fair warning — be very, very careful,” said Weisblat.
The Dyno Mode was specifically created to have representative driving controls while testing the vehicle on a chassis dynamometer or a rolling-road dyno where proper vehicle testing and calibration are done.
Weisblat went for a drive to test the performance of the vehicle. Without a Dyno Mode on, his Tesla Model 3 was able to hit 60 mph from a full stop in 3.1 seconds. According to him, his best time historically is 2.9999.
The DragTimes YouTuber turned on Dyno Mode and did another 0-60 mph test and clocked in 3.1 seconds but felt a bit of wheelspin. He gave it a few more tries and was able to clock 3.027 seconds on better pavement. Tesla pegs the 0-60mph time of the Model 3 Performance at 3.2 seconds while its Long Range All-Wheel Drive and Standard Plus versions clock 4.4 seconds and 5.3 seconds, respectively.
Weisblat’s final opinion on the Model 3 Dyno Mode is that it provides a slight improvement but might provide a bit more on a sticky drag track but it’s hard to tell.
“Dyno Mode, it’s pretty much just used for if you’re gonna dyno the car,” he said.
But of course, Model 3 owners who want to drift their Model 3s need to switch off its amazing traction control. Some owners turn off a wheel sensor but the system can go haywire since something is missing. The system will turn off ABS, Autopilot, regenerative braking, and even power steering. Furthermore, taking a wheel sensor out can potentially damage a vehicle.
Again, the Tesla Dyno Mode was created for testing Teslas on a dynamometer. If one will try to drive while it’s on, better stay away from other cars or pedestrians, or better yet, do it on a track.
Here’s the new Tesla Dyno Mode video from Drag Times:
Teslarati does not condone the use of Dyno Mode. Any information or opinion expressed in this article is to be processed at the discretion of the reader.

Starlink passes 9 million active customers just weeks after hitting 8 million
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
SpaceX’s Starlink satellite internet service has continued its rapid global expansion, surpassing 9 million active customers just weeks after crossing the 8 million mark.
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
9 million customers
In a post on X, SpaceX stated that Starlink now serves over 9 million active users across 155 countries, territories, and markets. The company reached 8 million customers in early November, meaning it added roughly 1 million subscribers in under seven weeks, or about 21,275 new users on average per day.
“Starlink is connecting more than 9M active customers with high-speed internet across 155 countries, territories, and many other markets,” Starlink wrote in a post on its official X account. SpaceX President Gwynne Shotwell also celebrated the milestone on X. “A huge thank you to all of our customers and congrats to the Starlink team for such an incredible product,” she wrote.
That growth rate reflects both rising demand for broadband in underserved regions and Starlink’s expanding satellite constellation, which now includes more than 9,000 low-Earth-orbit satellites designed to deliver high-speed, low-latency internet worldwide.
Starlink’s momentum
Starlink’s momentum has been building up. SpaceX reported 4.6 million Starlink customers in December 2024, followed by 7 million by August 2025, and 8 million customers in November. Independent data also suggests Starlink usage is rising sharply, with Cloudflare reporting that global web traffic from Starlink users more than doubled in 2025, as noted in an Insider report.
Starlink’s momentum is increasingly tied to SpaceX’s broader financial outlook. Elon Musk has said the satellite network is “by far” the company’s largest revenue driver, and reports suggest SpaceX may be positioning itself for an initial public offering as soon as next year, with valuations estimated as high as $1.5 trillion. Musk has also suggested in the past that Starlink could have its own IPO in the future.

NVIDIA Director of Robotics: Tesla FSD v14 is the first AI to pass the “Physical Turing Test”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine.
NVIDIA Director of Robotics Jim Fan has praised Tesla’s Full Self-Driving (Supervised) v14 as the first AI to pass what he described as a “Physical Turing Test.”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine. And just like smartphones today, removing it now would “actively hurt.”
Jim Fan’s hands-on FSD v14 impressions
Fan, a leading researcher in embodied AI who is currently solving Physical AI at NVIDIA and spearheading the company’s Project GR00T initiative, noted that he actually was late to the Tesla game. He was, however, one of the first to try out FSD v14.
“I was very late to own a Tesla but among the earliest to try out FSD v14. It’s perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn’t tell if a neural net or a human drove you home,” Fan wrote in a post on X.
Fan added: “Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.”
The Physical Turing Test
The original Turing Test was conceived by Alan Turing in 1950, and it was aimed at determining if a machine could exhibit behavior that is equivalent to or indistinguishable from a human. By focusing on text-based conversations, the original Turing Test set a high bar for natural language processing and machine learning.
This test has been passed by today’s large language models. However, the capability to converse in a humanlike manner is a completely different challenge from performing real-world problem-solving or physical interactions. Thus, Fan introduced the Physical Turing Test, which challenges AI systems to demonstrate intelligence through physical actions.
Based on Fan’s comments, Tesla has demonstrated these intelligent physical actions with FSD v14. Elon Musk agreed with the NVIDIA executive, stating in a post on X that with FSD v14, “you can sense the sentience maturing.” Musk also praised Tesla AI, calling it the best “real-world AI” today.

Tesla AI team burns the Christmas midnight oil by releasing FSD v14.2.2.1
The update was released just a day after FSD v14.2.2 started rolling out to customers.
Tesla is burning the midnight oil this Christmas, with the Tesla AI team quietly rolling out Full Self-Driving (Supervised) v14.2.2.1 just a day after FSD v14.2.2 started rolling out to customers.
Tesla owner shares insights on FSD v14.2.2.1
Longtime Tesla owner and FSD tester @BLKMDL3 shared some insights following several drives with FSD v14.2.2.1 in rainy Los Angeles conditions with standing water and faded lane lines. He reported zero steering hesitation or stutter, confident lane changes, and maneuvers executed with precision that evoked the performance of Tesla’s driverless Robotaxis in Austin.
Parking performance impressed, with most spots nailed perfectly, including tight, sharp turns, in single attempts without shaky steering. One minor offset happened only due to another vehicle that was parked over the line, which FSD accommodated by a few extra inches. In rain that typically erases road markings, FSD visualized lanes and turn lines better than humans, positioning itself flawlessly when entering new streets as well.
“Took it up a dark, wet, and twisty canyon road up and down the hill tonight and it went very well as to be expected. Stayed centered in the lane, kept speed well and gives a confidence inspiring steering feel where it handles these curvy roads better than the majority of human drivers,” the Tesla owner wrote in a post on X.
Tesla’s FSD v14.2.2 update
Just a day before FSD v14.2.2.1’s release, Tesla rolled out FSD v14.2.2, which was focused on smoother real-world performance, better obstacle awareness, and precise end-of-trip routing. According to the update’s release notes, FSD v14.2.2 upgrades the vision encoder neural network with higher resolution features, enhancing detection of emergency vehicles, road obstacles, and human gestures.
New Arrival Options also allowed users to select preferred drop-off styles, such as Parking Lot, Street, Driveway, Parking Garage, or Curbside, with the navigation pin automatically adjusting to the ideal spot. Other refinements include pulling over for emergency vehicles, real-time vision-based detours for blocked roads, improved gate and debris handling, and Speed Profiles for customized driving styles.
