The peak current draw on the LS1 coils is 9A EACH.   This can happen on startup before the EC2 can compute the proper dwell time.  Average amps is much lower during normal operation.

Prior to any discussion of fuses vs CBs; this issue needs some clarification.  Is it possible for more than one coil to be drawing this level of current at the same time?  I have 6 coils on my 20B; three on each circuit with a 16 AWG wire.  This could be frightening!
