Tracy,
 
Anyone had a problem with the Renesis crank angle sensor and had to change it.  I may have to get a new crank angle sensor, but first I want to check with you guys.
 
Tracy is probably gone to Colorado, maybe someone got this problem before.
I cannot get full power on my Renesis for takeoff on Controller A.  Seems like controller B works OK.
It is not the fuel mixture, I tried that.  Actually, when the throttle is wide open the mixture display goes up and down rapidly, from full lean to full rich and the engine surge.
 
I had a similar problem when I first installed and started the Renesis.  I had the EC2 controller then and had to get the EC3 to fix the problem.  Now it is coming back to me on the EC3, I think.  The problem then was with the crank sensor, the EC2 could not handle the sensor signal at more than about 5000 rpm.
 
I think the problem started progressively during the last few hours of flight, at first I thought it was a fuel mixture problem and was trying to ajust for that but now it is not a mixture problem.  Since the controller B has NO temp. sensor and works ok, I wonder if it has anything to do with that problem on controller A.
