Could I have an explanation of this table (this is as defined in TunerCAt)
The definition in Tuner pro is:
Spark adv temp. correction vs. load vs. temp (I think is the same table with a different label..)

As stated if is a "correction" table the values (MAP/coolant related) should be to add or to remove from a commanded spark.
Example: if in the main Spark table I have 2000 RPM 70 Kpa with a value of 40.08 deg.
If i see the "Base cool adv. correction vs. load vs. cool temp" table, I was thinking that a value will be added (or removed) to this 40.08 value..
This table has so bigger value that it's impossible that these value can be added (or removed).
At a load of 70 (i think this is a Kpa value) and at a temp of 32 °C, I have a value of 27,07 deg!! (at 80°C is 20 deg)!!!!
Simply I don't understand this table...
Help me I need to understand.
Thanks

Maybe i understand...
...let me know if I'm correct.
There is a constant called "Spark adv. base temp correction table bias".
this costant in my ANHT is 20.04 deg.
If the table "Base cool adv. correction vs. load vs. cool temp" has at 80°C 20.04 deg, this means that there is no correction.

20.04 deg - 20.04 deg = 0 deg correction.

if the table "Base cool adv. correction vs. load vs. cool temp" has at 44°C 27.07 deg, this means that there is correction .

27.07 deg - 20.04 deg = 7.03 correction (added or removed i don't know)

if the table "Base cool adv. correction vs. load vs. cool temp" has at 104°C 16.88 deg, this means that there is correction .
16.88 deg - 20.04 deg = - 3.16 deg
(added or removed i don't know)

Teortically if I modify the table accross the board to 20.04 (like the constant "Spark adv. base temp correction table bias" is), I will have NO CORRECTION.
I'm guessing right?

Sounds right to me. There should also be a temp threshold that disables this lookup altogether. On my stock chip it was somewhere around 112°F I think.
