Normally, you'd use them for a distributorless ignition as a coil per plug application, however they can be fired sequentially or every crank revolution (wasted spark coil per plug). They are the same monster coils used in Street Outlaws No Prep Kings contender, The Hulk!Įach IGN1A Smart Coil features a 19 amp IGBT ignitor built in and can be driven with a 5 volt logic level output - an MS3X or MS3Pro will run them directly (set spark output to going high), and we recommend a 270 to 330 ohm pullup if you're building a MegaSquirt 1 or MegaSquirt 2 to drive them and can fully charge with as low as 2.5 ms of dwell. The IGN1A Smart Coil by AMP EFI requires no CDI Ignition Module to produce 103 mJ per spark, with a longer spark duration (2.9 ms) than what you'd see with a capacitive discharge.
