Great job MIKE! Can you find   out the timing  when  the starter is engaged?

DBM ,thanks for taking the time to check , I didn't know what the wire did ,but assumed because it ran from the starter pos. cable that it might retard timing at startup .But perhaps it monitors voltage, ( volts drop when the starter engages) . We know voltage over 14v can cause damage to the TCI , and that voltage below 10v fails to produce a spark ,I don't know anything about circuit logic ,but does amperage tend to increase when voltage decreases? Could the TCI be  shutting down to protect itself from higher amps? We know if we leave the key on without starting the bike for a extended time the TDI can burn up, is this caused by applying constant voltage ,amperage or both?

Thanks for all your hard work and for sharing!
If the bike is really running such mild advance numbers, it either means that Suzuki is being very conservative, or that the combustion chamber is very efficient.
As to the ignition not working for the first revolution, I'm guessing that was done do eliminate kickback on starting.
