Early EFi Renault engines came with an unusual trigger pattern on their flywheel. 22 teeth followed by one tooth twice the normal tooth width, followed by a missing tooth twice the normal tooth width.
This pattern occurs twice to indicate TDC & BDC.
A trigger log of the flywheel has been made:

Can this trigger pattern be used with our existing Triggering algorithm?
