It looks closed to normal. See ignition controlled idle in the help file. http://www.hondata.com/help/smanager/in ... meters.htm
It has not got much vacuum for the highish idle speed, so if you make tuning / mechanical changes which improve the idle quality then you'll find the ignition variation will go down. I'd suggest looking at cam timing first.
This is a turbcharged B16a. Perhaps the high idle can be adjusted on the throttle body but if you look at the datalogs, the idling is pretty stable with very slight variation.
Moreover, the ignition map has been adjusted to the same numbers for the entire idling areas.
How could the ignition timing have so much variation on its own? I dont see why the camshaft timing would affect the way the ignition timing fluctuates so erratically.
