Table labeling

[Greenmachine501]

hey i was wondering if anyone could clarify how tables are labeled for example closed loop base afr target table 1 vs 2? what one should i be changing or both and the difference between the two? or say minimum spark timing 1-4 which is more confusing considering all values are the same.

The ECU code is not documented and it is a very time consuming process to identify the exact conditions under which each table is used. As a result, when the conditions are not known, the tables are labeled with numbers (1, 2, 3...)
In reality one of them could be "normal", another one could be "high load", "high IAT", "limp mode", etc.
You can either do some testing to figure out which one is used in your scenario or you can make similar changes to all of them.
