After completing a study of my 20B problems associated with the Renesis trigger wheel and sensor,  I am recommending that all users of these parts along with an EC2 engine controller install the sensor termination circuit shown on the attached drawing.

 

The Renesis sensor has different enough characteristics from the 2nd gen sensor that it needs this circuit to properly match it.  It replaces the 1000 ohm resistor that some may have already installed.   This addresses both the starting problem and the high rpm miss that have occurred in some installations.
