This behavior from your tilt inputs can be caused by the auto-calibration system the Z uses.
This system is intended to ensure the Zs tilt levels do not drift over time, but there are certain use cases where it can make matters worse. So if this is happening to you, we recommend the following steps to get the most stable and reliable performance from your tilt functions.
- Disable the "Tilt Auto Zeroing" option in the profile settings screen.

- Manually re-zero your tilt angles with the Z flat on your desk when you start playing; and maybe between some matches if you are doing an especially long session. You can create a mapping to do this by adding a "Reset / Calibrate Tilt Angles" outputs shown in the image below.

Additionally, the following suggestions may also help to provide a better experience with tilt.
- Set your tilt mappings angle to ~1.5-1.7° rather than the default 1.2° to reduce the chance of accidental activation.
- If
you are using tilt to hold down a key and it is releasing before you
want it to. Slightly increase the "noise value" setting on your tilts
(e.g from 0.5 to 1.0°).
- If your tilt inputs are activating when you lift your mouse to reposition it, try using a tilt input below 3°, or above 10°. Inputs below 3° are recommended because they are ignored when the mouse is lifted off your desk.
