if the sensor is "Shaky" it will never work correctly. No point doing anything until you fix that issue.

No more sync issues
The car is revving perfectly fine now.
I don't know why a 10nF capacitor won't work and a 1nF capacitor does work on my board.
I've also tested with a different conditioner board but same result.

The first test is to confirm that rpm (not load) is the primary condition, by revving to the loss point while parked in neutral. If it disappears, it's probably a tuning issue. If still there, then it's hardware.

If you want to test if the cap is the issue, reverse your VR + & - connections, and set Falling edge. Your Trigger Angle will change. Again, the signal in the video (at lower speeds) is relatively normal for most setups, but your issue appears to be the MAX adaptive function is causing an extended signal at the missing tooth.
