Overview
DIYAutoTune Smart Coils
DIYAutoTune Smart Coils by AMP EFI produce CDI-level spark energy--without a CD ignition module. They're manufactured with a 19 amp IGBT ignitor built in and can be driven with a 5 V logic level output. Normally, you would use Smart Coils for distributor-less ignitions, such as a coil-per-plug application; however they can be fired sequentially or every crank revolution (wasted spark coil per plug).
Smart Coil specs:
* Minimum voltage output (no load, at recommended dwell): 40,000 V
* 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 V
* Nominal dwell: 3.0 ms
* Maximum recommended duty cycle is 40 percent
* Requires HEI-type plug wire ends/boots
