    The IGN-1A Race Coil is a smart coil designed to provide 103 mJ per spark, with a longer spark duration (2.9 ms), exactly what is necessary for high rpm, high compression, forced induction and/or nitrous engines!

    Each IGN-1A Race Coil features a built-in 19 amp IGBT ignitor, can be driven with any 5 volt logic level output and can be fired either sequentially or every crank revolution (wasted spark/ coil per plug).  Maximum recommended duty cycle for an IGN-1A Race Coil is 40%.

    IGN-1A Race Coils are normally used for distributorless ignition as a coil per plug application, however they can be fired sequentially or every crank revolution (wasted spark coil per plug) and do not require a CDI ignition source.

    NOTE: Coil plug/pin set included - Spark plug leads not included

    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.

    IGN-1A Race Coil specs:

    • Minimum voltage output (no load, at recommended dwell): 40,000 volts
    • 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

    IGN-1A Race Coils are very solid, robust smart coils, however, excessive dwell or duty cycle may cause meltdown.  As with any race coil, the manufacturer does not provide a warranty.
