Controlling optispark with Ignition box
Is there anyway to control the optispark with an ignition box without the ecm? Going carb and already has msd opti spark coil and wires. Trying to keep it simple.
Has anyone used the PCM to only control timing by chance and left the fuel up the carb?
The goal was to use the parts he has in a relatively simple manner along with the carb setup.
