Why have any values in B5910 Spark ECT Table

[Chalky]

Getting into EFILive after a layoff. Added heads and cam and thought it would be a good to attempt to tune it myself.

I am going through the various calibrations and just don't see the need for this table. I would rather dial in timing with the fewest outside influences. Am I wrong here?

Once your engine is fully warmed B5910 should no longer come into play, but it may get you there troublefree with the richer values of AFR required for startup and cold idle.
