FC CAS Settings
 
I noticed in my trigger settings in my Adaptronic, it is set to 6, 156, 126, 96, 66, 36 degree's BTDC, however, I noticed that the 2 tooth trigger is exactly half way between 2 of the 24 tooth triggers. Wouldn't this mean that the first value should be 15 degrees, knowing that it is 30 degrees between each of the 24 tooth triggers, and the 2 tooth trigger is TDC on the front rotor? Actually, since the 2 tooth trigger is at TDC on the front rotor, wouldn't the first value on the trigger settings be 15 degrees ATDC, or 165, since the Adaptronic values are BTDC. Maybe I am overthinking this, I couldn't find any values online other than 1, 151, 121, 91, 61, 31, but that is further off than what I think it should be.

The worst thing about my timing is that my pulley is not matched with its hub, and the factory timing marks are a good 30 degrees retarded from what i calculated tdc to be. It runs with timing set to that, but the exhaust glowed at idle with the stock ecm. Therefore I don't have a definitive timing mark.

I might be over thinking it, and I should just run it with what works, but I don't like having no definitive timing for both the trigger wheel and my actual timing.
