Steps to Use:

With the vehicle on and the Accessport Connected, select "Troubleshooting" from the main menu.
On this menu select "Toggle Dyno Mode"

Some vehicles offer both a single and double roller dyno mode. Allowing you to use either a 2 wheel, or 4 wheel dyno.
A long hold of the center select button will bring up this long description of what it does.
A short press will begin the process to put the car into dyno mode. Keep in mind this is not safe for street use, and is only used while on a dyno.

For 992 vehicles only using AP3-POR-018 and AP3-POR-019 Accessports, users will see an extra prompt that states the engine must be OFF with the key in the ON position before proceeding or dyno mode will not enable/disable.

NOTE: If you find yourself proceeding with dyno mode with the engine running, the AP will leave the user on a blank screen and the vehicle's instrument cluster with several fault indicators.
To exit this, just unplug the Accessport from the OBD2 cable and reconnect it. The user will be taken back to the Accessport's menu and the instrument cluster will return to normal after about 5-10 seconds.
During the process do not turn the car on or off or disconnect the Accessport. If it was successful you will see the following message.

The cluster will show one of these messages.
If something caused the process to fail, double-check that this feature is supported on your vehicle and that your car was on.

Exiting Dyno Mode

There are two ways to disable dyno mode depending on the vehicle:
1. If you are using an AP3-POR-006, 007, 010, 011, 012, or 013, you can key cycle the car on and off.
2. If you are using an AP3-POR-014, 015, 018, or 019, you disable it by running through the same procedure you did to enable it on the Accessport.
To confirm dyno mode has been disabled:
1. No matter the vehicle application, the instrument cluster will no longer flash or display dyno mode or rolling mode.
2. In some vehicle applications when disabling via the Accessport (not key-cycling the vehicle), the user will just be taken back to the troubleshooting menu while in other vehicle applications, you will get the following message:

Do not use this system on the street, it is only designed for use when the vehicle is on a dyno / rolling road.

When And Why To Adjust:

Most vehicles are sensitive to any differences in wheel speed, this means that even on many linked dynos the cars can have issues. This feature enables those stability features to be temporarily disabled allowing you to safely dyno the car without issue.

Things To Look Out For:

This is for off-road dyno use only and unsafe to have active while driving the vehicle on the street.
