You should have a resistor installed on each P-lead to the EMS and use 2 pulses per revolution for a 4 banger. The Dynon will use the first RPM sensed from mag that comes online. When doing a mag check, it will use the last mag it senses.
EDIT: You should be using pins 32 and 33 for mag RPM, per the install manual.
