Hi Finn
I am using NGK plugs RE7C-L 6700 and RE9B-T
6701. I use unleaded 87 Octane car gas – alcohol but no lead
and normally go 100 – 150 hours on a set of plugs. The
current plugs were installed about 15 hours ago.
My EC-2 controller is about 20 years old.
My son-in-law Brayton Hackbarth and I are considering burning
new A and B chips because RAM and flash ROM doesn’t last
forever. What do you think of this? We estimate cost to be
about $250-$300 total.
Per Jeff Whaley - we are also going to
check to make sure the A & B chips are completely inserted
in the sockets.
We will look for any cracks on the circuit
board traces also.

I have an RX-8
in my RV-7a with Tracy’s EC-2 and EM-2. Recently while
cruising the engine lost some power and went into a rough
mode. It only lasted about 2 seconds and returned to
smooth running as soon as I switched to the B
controller. I landed and have been running it on the
ground to determine 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.
Has anyone else
experienced this problem and is there a fix?
Thanks
