I simply put values of 25 deg in there with a slope which made it much nicer to drive, I then considered disabling it completely, however this got me asking the question what were nissan trying to achieve with the warmup timing? Is it simply trying to warm the motor up faster by taking a few degrees out of the timing map? If so how much should you take out and if you disabled the map would the longer warmup time make much difference?
Thoughts?

and finally there is this map which also seems to add timing, when is this one accessed?

edit: and how does the after start timing advance table come into play, it looks as though it is adding timing on cold temperatures, do all the maps cumulatively add to the timing for the final number? When datalogging I found that using the stock warmup table I was only getting 7 degrees ignition timing on cold start which makes me think the other two maps were ignored.
