This is my prototype of simple EFI. I use NE555 as monostable oscillator triggered by high voltage field of the first sparkplug ignition cable. With a potentiometer I can adjust the output duty cycle. For this test I use white LED instead of fuel injector.
I built this prototype according to this article: http://www.rotaryeng.net/simple-cheap-555.html
