Adjustable 12v Flashing

ThirtyTwo said:

hello again

i need to set up a fuel injector controller that sends 12v to the injector at an adjustable rate from around 70 times a second to 130 times a second. i was thinking about something similar to a strobe light setup with a trimmer or regular potentiometer to adjust the rate. but i think injectors pull around 4 amps which to my knowledge is a lot for a small components circuit

Any ideas?

yeah an adjustable pulse width sounds like it would perform better, but it sounds like it would be a lot more complicated, could it still be done using a 555 with an adjustable pulse width and rate?
