First, look at the screen:

Adjust status (standing/crouching):

• Hold LB + Press RB → Swap stand/crouch status
• Warning: It’s kinda buggy

Enter tuning mode:

• Hold View (two squares) + Press Right Stick (RS)
• Red LED = tuning mode active

While in tuning mode (red LED):

• D-Pad Left/Right → Adjust X deadzone
• D-Pad Up/Down → Adjust Y deadzone
• Press RB/LB → Change guns

SAR only:

• Hold LT + Press RB → Switch between 1x and 4x
• Only adjust these

Exit and save:

• Press Y → Save settings and exit

Critical note

• You must hold both:
• LT (aim)
• RT (fire)
• At the exact same time for recoil assist to work
• Let go of either → it stops
