At that time, with the EC2, I could get the engine to run up to about 5000 rpm, after that it was missing, running rough and surging but would not run any faster.   I worked with Tracy on that, he told me to add diodes in the CAS circuit, it did improve the situation but did not correct it.  We tried a few diode configurations with no acceptable results.  Tracy mentionned that the EC3 controller would fix that problem so I ordered one and it did fix the problem.  But now it seems that it is comming back.
 
Since the problem is with controller A only, it could be that it is in controller A.  I did not dare fly with one controller operational only.  I get full power on controller B.   On controller A, the symptomes are the same as when I had the problem with the EC2 controller.

Rino,

What exactly is it about the Renesis crank angle sensor signal that the EC-2 can not handle?

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.
