7mgte cam sync trigger tooth issues

Attached is a log of my engine idling and having issues with cam tooth trigger sync. This setup worked fine for several tuning sessions and is now not functioning correctly and i can’t figure out why. Hoping you guys might be able to help. Its very hit or miss, sometimes it counts 24 (12t/1t) and sometimes it will count anywhere from 19-23 erratically. I have tried smaller and larger gap with the hall effect sensors, rising and falling edge, tested the sensor, isolated it from other electronic components nearby that could be interfering. Im really not sure whats going on. Talked with the company that sells the kit (sr fab) and they arent sure either.

setup as follows -

7mgte

emu black

sr fab 12t crank and 1t cam hall effect sensor kit

1zz coils

bosch 1000cc injectors

various other modifications unrelated to this issue

Any input is appreciated,

Did you figure it out, as I have the same kit with tooth count and may run into the same issue

Turns out the reluctor wheel on the crank hub was loose and intermittently moving around, usually under load. I talked to sr fab and this has not been an issue for them prior. I think this issue started when I first fired up my engine and had a bad timing belt that walked around. Changed the belt and it didnt walk around anymore. I think the original bad timing belt put axial pressure on the reluctor wheel and began pushing it off, then load/ vibrations caused it to move around causing my trigger issues.
