How about this, we're sidetracked.



I'll say, look, you just don't get it. You are measuring something that is not legitimate. There is no published spec anywhere that relates to a CONDUCTING coil with the engine off. Moreover, it depends on what I mentioned earlier---the entire voltage drop across the harness, starting with the battery, ---through the bulkhead (twice) through the ign switch and it's connector, etc etc etc.

What you want to do is either determine WHAT your coil "is" or buy one that you think will perform (aftermarket) and then follow the manufacturer's destructions as to what resistor to use.

The other thing that you cannot do anything about, is the incredibly poor quality of some of the late ECU boxes we keep hearing about. It just might be that due to poor QC in the internal circuitry, you don't get the full output of the coil that you should

ONE BIG FACTOR in that equation is the "CONDENSER." (Capacitor) Just exactly like a points system, an Mopar ECU has a condenser (cap) inside the box. IF THIS CAP is poor quality, or over or under capacity according to the coil, you won't get the spark that you'd expect.
