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 charge time @ 14V: ~2.1ms
- Coil charge time added @ 6V: ~8ms (If I understand this correctly, it means 'how many ms are added to the 14v charge time if the voltage is 6v)
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.
Connectors/pigtails sourced directly from Volvo:
- The plastic connector itself is part number: 9456341 (5 of these)
- The +12v feed pigtail is part number: 30656689 (5 of these)
- The ground and signal pigtails are part number: 30656688 (10 of these)
