Current throttle
When you move the throttle/brake you will see the bar move to the left and to the right indicating that the
throttle/brake channel of your controller is working. The value should move from -100 to +100 and in neutral
position it should be at 0.
Calibrate
When you change controllers or return to your VRC controller you should always re-calibrate the controller for
VRC Pro before you start VRC Pro. It is also advisable to re-calibrate after a certain period of use, like once a
week.
The calibration process is started by clicking on the orange Calibrate button. The Windows Game Controller
dialog will open.
Click on the ‘Advanced…’ button and make sure your controller is selected in case there are several controllers
connected to your computer.
Next click on the button: ‘Properties’ and select ‘Settings’ and then ‘Calibrate’. This opens the Windows Device
Calibration Wizard. This wizard guides you through the calibration steps.
Step 1: Find centre point
Don’t do anything, leave throttle and steering in neutral position. Click Next.
Step 2: Axis calibration
Move steering to left and right position and throttle/brake to maximum and minimum position several times.
You will see the axis move in all directions and when done somewhere near the centre of the calibration
window. When done click on Next.
Step 3: Verify centre position
Don’t move steering or throttle/brake, leave them in neutral. Click Next.
Step 4: Axis calibration
This is for the Z-axis, this is not used in VRC Pro. Click Next.
Step 5: Calibration complete
Click on Finish. Your controller is now calibrated and ready for use. You don’t need to restart VRC Pro after
calibration.
Controller sample rate:
When you move the steering or the throttle/brake on your controller this value indicates how many input
samples per second your computer or notebook receives from the selected USB device . The higher the
number the better the 'feel' of your controller. The maximum value is 125, limited by Windows itself. The
value may depend on the USB device itself and on the transmitter/receiver combination you are using.
Reverse steering:
For fixed USB controllers it might be necessary to switch the steering if the car, driving away from you, goes to
the left when you steer it to the right. Then click on Reverse steering ON.
Steering exponential:
Exponential steering changes the sensitivity of the steering. Normally it is linear (0) meaning that the steering
angle changes exactly with the amount of steering on the controller. Decreasing the exponential means that in
the beginning there will be less steering than your input on the controller, but at the end there will be more.
