I don't know much about electronics, maybe enough to scrape by. Hoping somebody here might be able to help. I'm building a fuel injector flowbench and cleaning system and using the Megasquirt ECU to actuate fuel injectors as if they were in an engine for flow testing. I need to generate a signal that will mimic the signal the ECU gets from the negative (distributor) side of the ignition coil. I need to be able to run the injectors the equivelent of idle speed to 10,000 rpm the pulse from the distributor would be 1/2 crankshaft speed so I need a device to generate 200 to 5000 pulses per minute for the ECU signal or 0 to 5000 will work fine. If anyone would like to check out the megasquirt: https://www.bgsoflex.com/megasquirt.html
I should ad that the flowbench will run off 115V ac and a regulated 12V DC power supply will power the megasquirt and high pressure fuel pump. A pot that I could turn to adjust the frequency would be the way to go.
I am capable of building a circuit from a schematic if someone could help me out with a circuit that would work.
Thanks for any and all help and happy holidays!
