Not really. Your ECU already has that setup, so there is nothing for you to add there. Hence me mentioning that ECUs are already designed to resist EM noise, which is why an "EMF gun" is not really feasible.
However, all the wires leading in and out of the ECU would act like antennas and pick up the EMF as well. In theory, If you pump in enough noise you could cause garbage data signals to be sent to the ECU, which could confuse it and cause some problems.
If you wanted to resist the hypothetical EMF gun, you would have to shield all those wires (up till the sensor endpoints). Considering they spider all over the car, it would be quite a feat to shield all of it. You would literally have to rip the entire car apart, shield every single trunk/wire in the loom, then reassemble it.
Quite frankly, in my mind a carb conversion would be easier, because you only have to do work on the engine itself, run a steel cable to the "go" pedal, and disconnect the ECU.
