MS2V3.0 Hardware Guide 3-wire COPs are ambiguous, many are high-current (needing an ignitor), some may be logic level with a built in
COPs with 4 or 5 wires have a built in amplifier (ignitor) so they require that you build the circuit in 5.3.1.3 and set the Spark Output to Going High. 5.3.3 Amplifiers (ignitor, power transistor, ignition module) An ignition amplifier module takes a 5V logic signal from the Megasquirt and drives a high-current ignition coil. This can be advantageous to keep ignition noise outside of the Megasquirt, or your engine may already have There are many different modules available on the market with 1, 2, 4 ignition channels.
Bosch style 1, 2, 4 channel ignitors and Quadspark 4 channel ignitor. Bosch 0 227 100 124 Cross references Intermotor 15015. This single channel module can be used to drive a single high-current coil. Dwell is controlled by the Megasquirt. Set the Spark Output to Going High.
