i want to ask about that. on a mopar electronic system the box does not control input voltage to the coil, the coil is what either needs or does not need the ballast resistor to attain the correct ohm ratings. i run a stock parts store box (looking at Rev-a-nator but am not sold yet) with a relay powered/resistor bypassed petronix 60K E coil that is HOT. now except for the actual controlling of the spark timing, retarding at rpm, what does a GM controller do that is better.
im also using brass contact cap and rotor, 8.5mm 500ohm wires, NGK plugs and recurved dizzy(yet to install my VC208 can).
