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 wi th external heat sink Requires HEI-type plug wire ends/ boots. Compatible with most brands of HT lead Box Contents1 x IGN1A Smart Coil 1 x Mating Connector Kit 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. Link User Guide: https://linkecu.com/documentation/IGN1A%20Smart%20Coil.pdf Show more
