Maintenance for Dual Sense and Dual Sense Edge* TMR sticks

Recalibration software (at your own risk)

If your stick center gets worn and drifts from the center eventually, it can be recalibrated to accommodate the current wear and be recentered, extending the life of your sticks even further. Read instructions carefully. Make sure the controller doesn't disconnect when saving.

Dual Sense Edge note:

Recalibration only works if the hardware modification on your module was left on by our technician. If it wasn't, you'll have to reach out to us.
