I purchased the V12 out of a 98 750. The documentation I can find shows the crank position is sensed by two Hall Effect sensors positioned 60 degrees apart on the bell housing while the flywheel spins 60 spaced tabs, except 2 tabs are missing. The 2 tabs signal the ECM's where top dead cylinder is on cylinder one. If the sensors are 60 degrees apart, then do two cylinders firing at the same time? If the second bank isn't firing at the same time, then the second sensor would be 45 degrees apart. The documentation I have doesn't talk about cylinder firing except to list the order.
Thanks for any help.
