This engine had no trigger sensor by default, so the following position was fabricated:

As the trigger wheel is from a newer version of the engine, the missing tooth position is fixed.
Problem now is that the positions of the sensor and missing tooth at TDC ends up in an "illegal position" in terms of first and second triggerpoint in the setup.
The way to handle this is to set up with a different firing order - starting with cylinder 3!
I've found this option in the ignition table, is there other places that needs to be corrected for this?
Should I place the secondary trigger to light up at cylinder 3 instead of 1?
(Will update with setup info from vemstune later)
