Crank Sensor pattern:
The choice to have the long gap detected at 30 BTDC and 0 TDC is weird.
- for fastest sync during cranking, 40 BTDC and 10 TDC would make most sense.
- for most precise timing during the whole range (and also for programmer's convenience) 90 BTDC and 60 BTDC would make most sense
Camsync:
The relative position of the cam (aving the camsync pulse coming inside the middle of the long gap) was a reasonable decision.
On both pics with the wheel, it turns anti-clockwise. The engine runs clockwise, but the pic is of the back of the wheel.
If we look at it as 15+3, 12+3+3 than the "funny part" is right after the 12.
- TDC is 30 crankdegrees after the single missing 2
- in other words, TDC is the 4th tooth after the single missing 2
There is a camsync signal 45 crank degrees before Cyl 1 TDC, then the second comes 135 crank degrees after TDC

- start from a sane config, than at the bottom of primary trigger dialog click the subaru configlet (so primtrig subaru mode), than change:
- nr of tooth on wheel = 12 (yes, not 30 !)
- tooth width = 30 degree (=3 * normal tooth)
- another_trigger_tooth=6 if 4 cyl
- (3 if 8 cyl, but assuming 4 cyl here)
- reference tooth from top to bottom: 0 6 0 6 ...
- disable camsync (burn, and might need to reboot)
Please measure+figure how to set trigger tooth and TDCdelay.
(tooth 0 is after the long gap after the group of 16 normal tooth).
