[Drunken DragPak]

The crank and cam sensors are the optispark, that's why it's called an optispark. It's an optical sensor that picks up a light source that's blocked by a timing wheel with slots to show where on the rotation TDC and every other cylinder is and the rpm increase.

I dont need to talk to anybody because I can clearly read the rules. The motor has a crank sensor and needs one to function.
