• Extract downloaded zip file, configure if needed and run MouseToVjoy.exe
• Configure game to use the vJoy device
• You can use the preset input configuration file for Assetto Corsa which can be downloaded here and placed in cfg/controllers/presets
• If game is not receiving input but vJoy Monitor is run MouseToVjoy as administrator

Configuration

Content Manager integration

Copy all files in MouseToVjoy folder to Documents\Assetto Corsa and change Settings > Content Manager > Drive > AC-related events to

Android touchpad setup

You can use an Android device as a touchpad if your computer doesn't have one. Download MouseToVjoy APK from here and install. The app uses USB tethering to communicate so you will be prompted to enable it. To prevent computer from using internet through phone set Interface Metric to 75 on the USB Tethering network.

Use keycode.info to get keycodes. Keycodes for mouse are left click = 1, right click = 2 and middle click = 4.

config.txt

Value	Description	Example
Sensitivity	The main sensitivity multiplier. Raw data from mouse is multiplied by this value and then added to X axis.	6.0
AttackTimeThrottle	Throttle value when pressed. When throttle is pressed, every 2 ms value is added to Y axis. The greater the steaper slope of attack.	200
ReleaseTimeThrottle	Throttle value when released. When throttle is released, every 2 ms value is subtracted from Y axis. The greater the steaper slope of release.	100
AttackTimeBrake	Brake value when pressed. When brake is pressed, every 2 ms value is added to Z axis. The greater the steeper slope of attack.	200
ReleaseTimeBrake	Brake value when released. When brake is released, every 2 ms value is subtracted from Z axis. The greater the steeper slope of release.	100
AttackTimeClutch	Clutch value when pressed. When clutch is pressed, every 2 ms value is added to RX axis. The greater the steeper slope of attack.	200
ReleaseTimeClutch	Clutch value when released. When clutch is released, every 2 ms value is subtracted from RX axis. The greater the steeper slope of release.	100
AccelerationThrottle	Add linear acceleration on throttle axis. 0 to disable, greater then 0 to enable.	1.01

UseForceFeedback	Use force feedback.	0
RequireLocked	Requires the mouse to be locked.	1
MouseHook	Use a global mouse hook to prevent mouse movement/clicking while locked. Doesn't always work properly so disabled by default	0
UseWheelAsShifter	Use mouse wheel as a sequential shifter. Mouse wheel up for next gear and mouse wheel down for lower gear.	1
UseWheelAsThrottle	Number of steps to use for mouse wheel as throttle. 0 to disable	10
WheelThrottleMiddle	Number of steps to use for mouse wheel as throttle when middle button held. 0 to Disable.	30
CenterMultiplier	How much center reduction to use. Greater then 1 to make center less sensitive while making ends more sensitive. Lesser then 1 to make center more sensitive while making ends less sensitive.	1.20
RequireClutch	Percentage of clutch in required for H-Shifter to shift. Max value 100	0
VJoyID	VJoy device ID to use	1
DisableKeys	Disable keyboard when touchpad active	1
Touchpad	Use precision touchpad as touchpad (Z and RX axis). Requires precision touchpad drivers which can usually be installed if your laptop didn't come with them.	1
TouchpadApp	Use MouseToVjoy app on an Android device connected over USB as touchpad (Z and RX axis). 0 to disable, 1 to enable and 2 to open background picker in touchpad app	0
TouchpadTablet	Use drawing tablet as touchpad (Z and RX axis)	1
TouchpadXInvert	Invert the touchpad X axis.	0
TouchpadYInvert	Invert the touchpad Y axis.	1
TouchpadXPercent	Percentage of touchpad X axis to use such as 100 for full and 50 for half.	65
TouchpadYPercent	Percentage of touchpad y axis to use such as 100 for full and 50 for half.	70
TouchpadXStartPercent	Percentage of touchpad X axis to start at.	30
TouchpadYStartPercent	Percentage of touchpad Y axis to start at.	25
TouchpadAxisDisable	Disable a touchpad axis. 0 = none, 1 = rx, 2 = z	0
TouchpadButtonsH	Number of horizontal touchpad buttons.	4
