just a idea can i use my edis as amp for cops
realistically you want to run fully sequential to run cop's if you run them wasted spark they tend to die as your running them at double the duty
they are designed for.
there are many different types of cop's requiring different circuitry to run them. some require a logic level signal to fire them either going
from 0-5v or 5-0v or 0-12v or 12-0v. then there are the dumb ones that only have two wires that dont have a built in ignitor so need an extra high
power drive circuit (bip373's can do it).
what cops do you have what ecu/trigger system/fuel delivery system?
have blade cop toyota celica cop its got megasquirt and edis at mo
