High Power Inductive Coil with built-in ignitor.

  • Produce 103 mJ per spark, with a longer spark duration (2.9 ms) than what you’d see with a capacitive discharge
  • Built-in ignitor with external heat sink
  • Requires HEI-type plug wire ends/ boots. Compatible with most brands of HT lead

Connector Pinout:

A – Ignition signal from ECU

B – Logic ground, connect to ECU ground

C – Spark wire ground, connect to cylinder head

D – Power ground, connect to battery negative E – 12 volt power.

The coil dwell starts when a 5 volt signal is applied to pin A and the coil fires when the voltage drops to zero.

The signal is similar to an LSx coil, although it does need a bit more current to trigger.

Smart Coil specs: Minimum Output Voltage (no load, at recommended dwell): 40,000 volts

Maximum Output Voltage: up to 81,000 volts (+/- 10%) Output energy: 103 mJ Spark duration: 2.9 ms

Primary resistance: 0.5 ohms (not directly measurable) Primary inductance: 4.8 mH (not directly measurable) Secondary resistance: 8,500 ohms

Secondary inductance: 22.5 H Turns ratio: 71.1 Maximum current: 19 amps Maximum battery voltage: 17 volts Nominal dwell: 3.0 ms

Excessive dwell or duty cycle may cause meltdown. As with any race coil, the manufacturer does not provide a warranty.
