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
Currently running:
- Coil charge time @ 14V: ~2.1ms
- Coil charge time added @ 6V: ~1ms (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 have built in BIP373 drivers and pull up to +5v to fire. VEMS is configured as 2+6 with logic level outputs going to the coils. 'Invert driver output' is set to 'Disable'.
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)
