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.
