==== Adjustment Steps: ====

* Loosen the 3 screws holding the circuit plate slightly—do not remove them.
* Push the plate upward toward the casing (without side-to-side movement).
* Move the plate just enough so the swiper arm no longer runs in the grooves (less than 1mm).
* Swing the swiper arm through its full range, ensuring it never intersects old grooves or leaves the carbon track.
* Tighten screws securely after confirming correct alignment.

'''Tip:''' If you can’t move the plate far enough up, try moving it down.
If that’s still not enough, slightly enlarge the screw holes with a file.
Proper ''side-to-side'' alignment of the carbon track is more important than top-to-bottom.

Once adjusted, reinstall the AFM into your car. You can stop here or proceed with the following procedures.

Now’s the time to use your '''dielectric grease'''—apply it to electrical connectors to seal against
moisture, prevent corrosion, and ensure reliable AFM operation. If you don’t own an air/fuel ratio gauge,
avoid proceeding further unless you’re confident in air/fuel tuning, as the next steps adjust the mixture.

⚠️ Performing the following procedures is done at your own risk.
