Solid wire ignition
i guess the reasons people say NO is radio interference
i.e the FCC might be upset :)
and if its going to mess with your ECU it will
if it isn't going to it won't
ECU as in something with a computer in it
i doubt the FBO box or a mopar orange box or an HEI would be considered a computer or an ECU if we use ECU to mean the brains of a modern engine control system
they have more in common with a switch than a computer
