If you're only planning to run at fixed RPM then the injection timing could be fixed too.

Invert the pulse stream - the LV side of the coil in a spark engine is charging between firing the plugs (this is the dwell angle). When you want to issue a spark the supply it cut.

In your case you want to have 0v, and only issue 12v when the injector needs to fire.
