you are looking for "Spark extension slope" this will be say 5degrees per 1000rpm, from there you should be able to extend the table to identical to what the car sees.

So the Tune I used to run in $A5 would have increased 5deg per 1000rpmonce outside of the spark table, unless the Param "Spark extension slope" had a different value to stock?

just had a look in your tune, its 2 degrees per 1000 .....

sorry the name is F1 Table Extension Slope.

so will be whatever the value is in 4800rpm cells and then 2 degrees added at 5800rpm etc.

just to be clear, that is 2 degrees at 5800, but the rows between 4800 and 5800 need to be averaged out to keep it smooth and so on.
