Software calibration vs Hall effect replacement
Software calibration fixes wrong centre and uneven range on a sensor that is still stable. Hall effect (or TMR) modules remove the carbon wear path but do not arrive pre-aligned, you still write centre and range after the swap. Calibration on a worn pot is temporary; Hall on a good install plus calibration is the long-term repair story.
Which path matches your scan
| Scan pattern | Software cal alone | Hall / TMR module |
|---|---|---|
| Steady off-centre rest | Often enough | Optional upgrade for longevity |
| Jitter at rest | Wrong tool, may worsen feel | Replace, then calibrate new module |
| Drift returns in minutes | Hardware unstable | Replace, then calibrate |
| After any module swap | Required finishing step | Same. NVS still holds old reference |
Cost and effort (rough bands)
Software calibration in DriftNo is free on the diagnostic path. Hall modules add parts cost and install time but remove the usual wear mechanism on stock pots. See the repair cost guide for shop vs DIY bands.

FAQ
I fitted Hall effect sticks. Do I still need to calibrate?
Yes, and it matters more than people expect. New modules rarely land on the exact centre and range the controller expects, so a freshly repaired pad can still read off-centre until it is calibrated. Run a scan, calibrate centre and range, then re-test to confirm the repair.
How do I know whether to calibrate or replace the stick?
Run the scan first. Stable readings with an off-centre rest point point to calibration. Noisy, inconsistent readings, or drift that returns shortly after a fix, point to a worn module - replace it, then calibrate the new one.
Can calibration make drift worse?
It can on a badly worn stick, because you are moving the reference point of a sensor that is no longer consistent. When the scan sees signs of wear, DriftNo recommends replacing the module first rather than calibrating over the problem.
Does DriftNo fix stick drift permanently?
It depends on the cause. If the stick rests off-centre but is otherwise stable, calibration can correct it and the correction holds. If the potentiometer is worn (scratchy, jumpy, drift that comes back within minutes) no software can repair that. DriftNo tells you which case you are in instead of guessing.
Can I calibrate without opening the controller?
Yes on DualSense and DualShock 4. Connect over USB in Chrome or Edge and DriftNo can write centre and range to the controller itself, so the correction transfers with the pad to your console. No disassembly and no soldering.
Let the scan pick the path
Stable offset → calibrate. Noisy rest → replace, then calibrate.
