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.
