No cam signal (MS3)
Had VVT head. Swapped to non-VVT head. Cam sensor wiring was extended, but wired the same as before. It has ground, reference, 12v going to it.
Not getting a signal for it in the MS.
Have 36-2 trigger wheel (spark mode set to Miata 36-2). Ignition input I've tried both rising and falling edge.
Have tried 3 different cam sensors. One from a 99, other two came out of the previous VVT head at various points. I know for a fact at least one of them was working last year. Unlikely any of the 3 are actually bad.
Attached is composite log if it's of any use? Unsure what else to check. Also attached current tune.

This is how I have the cam sensor wired: https://i.imgur.com/mkG2va7.jpg
Left to right - ground, signal (green/yellow wire from car - '96), 12v.
