just had a quick few questions I can't seem to find searching..

On timing and the SPARK MAP

1. During cranking, is the engine starting on base timing then advances to idle advance once idle RPM is met? Or is it starting on idle advance?
Scenario: I would like to run 18*btdc at idle, but I want to only crank/start at 14*btdc to help hot starts. Can this be achieved with base timing(14*btdc) idle advance(18*btdc), or would it be better to set the idle advance at 14*btdc and have (1100 45kPa) set to 18*btdc

2. Are you inputting the target degrees you want to advance to, or the number of degrees you want to advance to?
Example: Idle timing is set at 18*btdc, I want (WOT 3000 95kPa) to be 34*btdc. On the handheld do I input 34* to indicate the target degrees, or 16* to direct how many degrees to advance. basically who does the math, me or the handheld
Thanks in advance (pun intended)

From what I have learned.. The engine will crank on your base timing 14.. then once running will adjust to what you would like, 18. Set the timing at the various breakpoints to the timing that you want it to run at.. I use 34 on my WOT settings for 3000 and 6000 rpm, and higher settings for the cruise or 45 KPA settings ( i use 44 degrees, at 45kpa, to bring in more advance at cruise or light loads) at 3000 and 6000.

At 1100 rpm , if increase from my idle of 18 to about 23 for light load and about 20 for WOT

If you want 34 degrees at 3000 95KPA, then enter 34 degrees.
