To my knowledge, there is no dyno mode. Maybe they said dynamic control or dynamic mode. The bars solely affect shifting; they have absolutely nothing to do with horsepower. The only two HP modes that differ are 400 and 500. Sport 500 also improves your control reaction. When in any shift mode other than “DSC Off and Sequential Mode,” the bars on your automobile go from 1 to 5. Only when DSC is turned off and you are in sequential shift mode can you reach shift mode 6 (the sixth bar). Your manual explains this in detail.

What does Dyno mode accomplish?
Many of your car’s safety features, such as traction control, automatic emergency braking, and stability control, are disabled by dyno mode. These safety features exist to increase the predictability of your car’s handling, especially in circumstances where you would otherwise lose control.
What does dyno in a car mean?
A dynamometer, commonly referred to as a “dyno,” is a tool used to gauge power or torque. A dynamometer is made to replicate different speed (RPM) and torque (Nm or lb-ft) requirements for chassis or engine applications. Power (HP or kW) can be derived from this data. In turn, this gives a quick picture of the chassis’s or engine’s performance for comparison with the maker’s requirements. A dynamometer often allows the operator to change the load delivered to the equipment being tested to imitate particular requirements.
How can I activate the Dyno mode on my Tesla Model 3?
It remains in place. It was transferred to the software menu about a year ago. When the “Model 3” logo starts to throb, press “OK,” write “dynotest,” and then depress the left turn signal.
On the road, though, it doesn’t accomplish anything noteworthy. Simply keep your speed at 15 mph. Maybe it only functions on a real dyno?
Now you go to the software settings screen, which displays a picture of your car, your mileage, release notes, etc. and has your car’s logo in big letters, i.e. “Model Y” for me, in case anyone trying to do this in V11 is unclear on what the OP means by “main screen” (or if that’s where it used to be). Consequently, once there, hold down the left blinker and the stylised model name logo until a “password” dialog box opens. Next, type “dynotest”
How can I exit dyno mode?
Tesla’s 2019.40 software upgrade appears to have included a new capability that nobody was aware of until it was found in an EPA file.
The EPA filing and description of “Dyno Mode,” which was introduced to production vehicles on October 7, 2019, and subsequently made available to the full Tesla fleet in their 2019.40 software update later that month, were found by Long Ranger of the Tesla Owners Online forum.
WARNING: Dyno Mode disables a number of important safety systems, which can get you into trouble quickly if you are not careful, especially with RWD. People have reportedly underestimated the degree to which these safety systems keep their vehicles in check, leading to accidents and damage, as seen in the video below. Use this function only on a closed circuit, far from other vehicles and people on foot. You do so at your own risk when using Dyno Mode.
Press and hold the Tesla T logo on your in-car display to activate Dyno Mode. A prompt requesting for code will come a little while later. Enter “dynotest” at this point, then after you hit OK, keep holding down the left turn signal.
In your Tesla, choose “Power Off” from the Safety and Security page to disable Dyno Mode.
The whole explanation from the EPA file is as follows:
The implementation of user interface (UI) features that give all users access to our “Dyno Mode” is now being finished by Tesla, Inc. To preserve representative driving controls when doing testing on a chassis dynamometer, this function must be activated. On October 7, 2019, production will begin, and during the whole month of October 2019, version 2019.40 of the Tesla fleet will be updated to include access to Dyno Mode.
Dyno Mode implements the following capabilities to maintain the right driving functionality and behavior:
– Make the torque split exactly as it would be while driving in a straight line.
Regenerative braking is inhibited when the Stability Control and Traction Control systems malfunction, as is the case on a dynamometer when driving is detected but movement is not. This prevents unwanted braking torque from causing traction or control loss on low friction surfaces. Stability control and traction control are disabled to preserve the most accurate driving energy usage. Disabling these systems stops them from interfering with regenerative braking behavior.
The user can enable Dyno Mode by doing the following actions:
1. The car needs to be in park.
2. Press and hold the Tesla “T” logo at the top of the screen while continuing to hold down the left (turn signal) stalk.
3. Type “dynotest” as the Dyno Mode activation password.
The user can turn off Dyno Mode by clicking the “Power Off” button in the UI’s Safety & Security page.
By October 7th, 2019, we hope to have this Dyno Mode option ready for installation in all new production cars. We will provide this capability to our US fleet throughout the month of October, enabling all Tesla cars to go into Dyno Mode.
What is the BMW roller mode?
A supposedly Test stand mode or roller mode is not available on all vehicles. This is a unique mode for the brake test as well as for measuring test bench performance. For instance, if you drive a BMW car with the X Drive four-wheel drive off, the roll mode all-wheel drive on the front axle may be deactivated in particular circumstances. Or, to put it another way, just the rear axles are still powered. Additionally, all electronic aids like traction control and ESP are totally deactivated.
A power measurement is typically attainable in this mode without any issues, and the vehicle’s drive/power controls are not automatically made. A pure test result is also actionable. The role mode is frequently activated through a secret menu in BMW automobiles. As an illustration, take the BMW F30 335i. When you push the trip meter reset button on this car for a long time, the unique menu appears.
What advantages does dyno tuning offer?
Engine output, including horsepower, torque, and the air-fuel mixture, is measured by dyno tuning. Depending on the kind of your car, your technician can modify the air fuel mixture and timing to your chosen settings. This kind of adjustment is possible for various engine loads and circumstances. It is a unique tune-up that improves your ride and boosts your car’s effectiveness and performance.
Dyno tuning aids in fine-tuning your car for a more economical and comfortable ride. Common problems like poor gas mileage, surging, pinging, trouble starting the car, or a lack of power are also helped by this technique. If your car needs performance repair, you might think about getting a dyno tune to get the best performance out of it. Many of these issues can be resolved with a dyno tune.
A dyno tune optimizes the performance of your vehicle by using the ideal settings that are fitted to it and its equipment. A dyno tune often offers the most power, improved driving characteristics, high fuel efficiency, and a smoother ride. Your car’s horsepower is increased, and its fuel efficiency is restored to factory levels. Additionally, it lessens the chance of backfire.
Additionally, dyno tuning can help you avoid future expensive problems. Compared to a car that has not been dyno tuned, an engine that has been tuned does not need to work as hard. Dyno tuning also lessens the wear and strain on the car. Your engine’s lifespan is also prolonged.
When performing dyno tuning, a technician first conducts an interview with the owner of the car. The mechanic will inquire as to if there are any specific issues to watch out for, such as a lack of power, poor gas mileage, trouble starting, or surging.
A technician visually inspects the vehicle for issues like burnt wiring, a filthy carburetor, or a damaged vacuum line in addition to checking the engine compression for any potential issues. The expert then decides, based on how you drive the car, what heat range is best for yours.
The distributor is then taken out and put in a special machine where it is put through a rigorous testing process. This test keeps track of the distributor while it is really in use, giving us a better understanding of how sound its mechanical construction is. We change the centrifugal advance rate and make other adjustments to fit the vehicle’s ideal settings, including maximum gas mileage, after determining whether the distributor is mechanically sound. The ignition system is examined, and any necessary replacements are made.
The dynamometer is used to test your car while the engine is operating. As we track the performance of your car, we test it under various circumstances, including various loads and speeds. Throughout this testing, we keep an eye on all of your carburetor’s circuits. To ensure optimal efficiency and drivability, we modify the circuits.
Customers are given a thorough test report with the tune-up requirements after dyno tuning. You can have this report explained to you in detail by one of our skilled professionals.
Dyno tuning is it safe?
One of the simplest and safest ways to increase your car’s power is through dyno tuning. You can assemble components all day long, but without modifying the ECU, little will change. In fact, you can end up in worse shape than if you hadn’t worn those components.
Does dyno tuning boost horsepower?
Unfortunately, there are limitations. It’s quite challenging to quantify the increase in horsepower or torque. Everything largely depends on the components that you have. Tuning your automobile will undoubtedly give you a lot of horsepower if you have fitted a lot of performance components, such as an exhaust system, turbo, and cold air intake.
A dyno tune may likely add 10-15 horsepower to a stock car, to give you an idea of the range. However, if you have performance accessories like an exhaust and a turbo, you could add 50 horsepower or even more, depending on your engine and the accessories you have.
