I have the 13 BREW. What did you do to change back to the old style CAS? Wouldn't I have to change the front cover and e-shaft?

Brian, 

Do you know anyone that would let you borrow their EC-2 to try?  You want one configured for the old style CAS.  This is what I did and it confirmed that the CAS was causing my problems (same as yours).  I finally gave up on the crank-mounted CAS and went back to the original style CAS.  No more high rpm mis-fires.

I just installed the Magnecor wires, put on a smaller prop, re-routed the CAS sensor wires to a location further away from the secondary igntion leads, and ran up the engine. No joy- I still get lots of misfiring above 5200 RPM. Wondering if the issue might be with my EC2.
I still have questions about how my CAS is wired, on the 13BREW the CAS is next to the trigger wheel, it consists of two hall effect sensors, one to count every 30 degress,and one that counts every 360 degrees. The EC2 has three wires going out to the CAS- one to provide voltage to both sensors, and one wire each (#22  &  #23 ) to read each sensor. My question is- is polarity a possible issue with hall effect sensors?
 
Also, does the EC@ fire both leading and trailing plugs simultaneously?
