I'm currently in the middle of this swap and would like to start working on the tune. Today I was comparing my 98 tune to a 02 tune and noticed that many of the tables were different. Now do I have to migrate any table that is different from my tune to the later tune? Are there any tables that I can just leave alone? What about the tables that use different parameters in the columns/rows? For example, the {B5911} Spark IAT Table. In my 98 tune the column is in kPa while the 02 tune uses grams/cylinder. Any help is appreciated!
