Default RE: PCM or FM RX on an electronic iginition engine?

Not all engines need shielded plug cap. None of the dozen engines I have do. Make sure you use a resister type plug in it though. Most Mfg. have an R in the plug # such as Champion RCJ7Y. Make sure you do a range check. It will be slightly less with the engine running.
