It is for mainly carbed engines, most modern EFI systems include programmable ignitions. See point #6 below, it provides crank cam signal for sequential EFI. It is for Mopars, requires distributor modification, does not use Mopar ignition box or ballast resistor.
Some of the gains are as follows:
1. Electronic advance, elimination of flyweights and vacuum dash port for accurate programmable advance curves. Electronic advance provides more adjustment than can be done with flyweights, slots and springs .... An example is timing retard for rev limit, timing retard for turbo.
2. Elimination of distributor rotor and long plug wires.
3. High energy multi-spark. Longer duration than MSD CDI.
4. Programmable rev limit.
4. Simple real-time tuning.
5. Data logging and presentation of RPM, Ignition advance, manifold pressure, battery voltage and engine temperature.
6. EFI ready timing reference signals, including tachometer signal.
7. Fuel pump keep-alive signal, for running engine, shuts off pump 0.2s after stall condition.
