Coils are OE Volvo from an S80 T6. They have built-in power stages and are suspected to be internally identical to the Bosch Motorsport Single Fire PT coils, data-sheet here: http://www.vems.hu/files/MembersPage/KarlBuchka/Single_PT.zip

Spec sheet gives (assuming 6A primary current, reasonable?):

Coil pin-out:

Pin Designation
1 Trigger
2 Not Used
3 Ground
4 +12v

The coils pull up to +5v to fire. I believe I need 'Invert Driver Output - Enable' for this to work.
