Joe,
  Have you made sure the bypass plug in the front of the eccentric
shaft is completely closing off the opening in the shaft ?? Your
oil pressure at high rpm seems a little too low to me if your gauge
is accurate !! IMHO

Tracy,

 

I reset the EC2 to the "RV-Otter" settings (cold start on), and it is very close now.  Got rid of most of the staging stutter too!

 

Now a question about oil pressure for the group.  Since I removed the balls and springs from the rotor jets and have stock jets, here are my oil pressure readings.  Somebody let me know if this looks like enough flow.

 

Cruising at 5350 RPM,

 

Oil Temp     Oil Pressure

160                86

195                75

201                70

 

and at idle RPM with Oil Temp at 170,

 

RPM         Oil Pressure

1250              19

2000              37

Bill,

If/when you find a solution to the annoying surge during high idle/taxi

let us all know what it is.

I too am experiencing this annoyance.

I think we need to set the staging point higher but have not tried this yet.
