An aircraft piston engine magneto having a magnetic rotor and an ignition circuit with a reconfigurable charging coil inductively coupled to magnetic rotor. The charging coil includes multiple coils inductively powered by the magnetic rotor and electronically reconfigurable from a higher turn, lower amperage power coil for use when running at low speeds into a lower turn, higher amperage coil at higher speeds. The charging coil is configured into the higher turn coil by electronically connecting the multiple coils in series, and into the lower turn power coil by electronically connecting the coils in parallel. The ignition circuit is a fully electronic ignition circuit that generates and distributes ignition pulses to the piston engine spark plugs using only non-mechanically actuated electrical components within the magneto.
