This engine will be running full sequential COP, so the relationship between crank and cam is important.
It is possible to run this engine in wasted spark using the COPs, and ignoring the cam sensor. In order to do this, you need to recompile VEMS with the ign_dualout (double check this). This will allow you to fire two neighboring outputs at once. You may need to organize the outputs appropriately so they fire the correct coils.
The firing order of the engine is 1-5-3-6-2-4
