startup spark
what time table does the 7747 computer use to start engine? does it start at 400 rpms (21 degrees) plus the value of "startup spark added", or just the main spark map.

If you mean CRANKING spark, it's JUST base timing, and absolutely nothing else.
STARTUP (after rpm is greater than 400 rpm) has a startup spark adder, and coolant vs load adder (biased against it's offset), and main spark table. If your xdf is set-up properly, it's just add the 3 numbers together.
