Dear Tech Folk, I have a horizontally opposed 2 cylinder 2 stroke .It fires the ignition on both cylinders @ the same time.At present has a TCI system with 2 internal coils 180 degrees opposed with 2 magnets in the flywheel opposite one another.This engine is going into an ultralight so for reliability & safety I wish to convert to dual ignition. Being technically challenged my question is can I utilise the TCI system to achieve this or will I have to convert to CDI. The engine has no charging system but plane will be equiped with a 12 volt battery. I have doubled up on a CDI system in the past so have no real problems with the mechanical issues. I would be most great full if someone could give me a solution & a list of components I need, Looking forward to a solution. Regards Graham.
