Ed,
When you said, "I fly with my timing set 3 forward of the center position
which means 2 retarded or 2* 1.875=3.75."
did you mean " I fly with my timing set 3.75 retarded, i.e., 'two button pushes', i.e., 3.75 degrees from 35 degree max
static BTDC."?
In other words, I'm asking for clarification on the ". . . set 3 forward of the center position . . . " phrase. Was the "3" supposed to be "3.75"? Or is there some other physical measurement with respect to ". . . the center position . . . " of something not explicitely mentioned?

Buly,
Last I recall, Tracy's instructions were to set the static timing at
approx 35degree BTDC for maximum advance. Then you can retard the timing
from that point using the EC2 mode 8? (Ignition Timing Adjustment mode)
for best performance. Each time you push the program store button in mode
8 it changes the timing approx 1.875 deg. There are 10 adjustments
possible for a total of 9.375 degs. Or when set at 35 deg static you
would retard the timing to a minimum of 35-9.375 deg = 25.625 deg BTDC.
I fly with my timing set 3 forward of the center position which means 2
retarded or 2* 1.875 = 3.75. Which would give me 35 - 3.75 or 31.25 degs
BTDC for normal flight.
