Smart Coils

IGN1A smart coils! These coils are designed to deliver a hotter and cleaner spark then stock style coil near plug. Maximum recommended duty cycle is 40%.

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 than the LSx coils.

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

These are very solid, robust coils that will do well for you if dwell is set up correctly.  However, they can be killed by excessive dwell or duty cycle.  As they are race coils, the manufacturer does not provide a warranty.
