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.

Subject: [FlyRotary] Timing adjustment
Now since I joined the NA crowd, I have to adjust my timing accordingly. A racer told me to do it at 3K engine RPM. Last night I run the engine at 3K RPM and played with the timing from the EM. Noticed the RPM changed with change in timing. I'm thinking if it is right to run the engine to 3KRPM and someone rotate the CAS for best RPM and leave it there. Or just use the timing light as the manual preaches?
