I have an RX-8 in my RV-7a with Tracy's EC-2 and EM-2.  Recently while crui=
sing the engine lost some power and went into a rough mode.   It only laste=
d about 2 seconds and returned to smooth running as soon as I switched to t=
he B controller.   I landed and have been running it on the ground to deter=
mine the cause.  It has occurred 3 or 4 more times and only lasts seconds. =
 I believe I have determined that one rotor quits firing when it runs rough=
.
Hi Dennis, I have not experienced that problem myself but it sounds like an=
 intermittent problem someone else had a few years back - at that time I su=
ggested checking to ensure the Controller Chip is securely seated in the PL=
CC socket of the EC2 board ... it worked ... something you can check or eli=
minate.

Has anyone else experienced this problem and is there a fix?
Thanks
