I need to control from one to four fuel injectors, these will be controlled by a potentiometer (throttle regulation)
problem is injectors are 12v and I need to control voltage per cycle and duration of it to vary fuel delivery to engine.
board, Arduino nano
-fuel delivery control for 4 injector
-injectors from min5v up to 12v (fully open) and control of injection time (voltage vs time)
-termistor/temperature sensor to condition when it should work and when cold not to work
-rpm reading from the hall sensors
please no heroes!! You need to be able to know perfectly how it works combined with the engine, please no copy pasters!! there are plenty of free codes out there! clean code no more surprises, if you don't have experience interfacing it with a engine having it's own power source and magneto please don't bother.
