At the same time, the ignition could be done direct fire, coil on plug. I can use same hardware I am developing for the V8 COP ignition. I designed a similar system for 2.2L engine, and used the OEM ECU for timing control, diverted to coils. The reason would be easier drop-in eliminating crank sensor and bellhousing mod. The EFI trigger would come from my ECU associated with ignition.
