Tracy,

Could you please elaborate a little about some of the symptoms that you have heard or know about that this will cure?  My Renesis starts fine, but I get some rough running at speed.  I have had backfire once.  Also, when I advance the throttle, the engine does a large hesitation before it takes off in a quick rev.  Like a car might if it didn’t have an accelerator pump.

My air/fuel indication seems to be unstable also at speed.  Is that related?

 

I put the circuit together this afternoon and will install it, but I am wondering what symptoms I might expect to go away… 

 

Thanks,

 

Bill B

Forgot to explain how to connect it.  The two leads are to be connected directly across the two leads of the Renesis crank sensor.  It can be installed near the sensor, near the EC2 or anywhere in between, whatever is easiest.   It is not polarized so it doesn't matter which terminator lead goes to which sensor lead.

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.
