I'm on the verge of pulling the trigger to upgrade my E38 to the 2.5bar map, mainly for the increased clarity in the maf in addition to the built-in VE table.
What happens to my existing tune when I upgrade the OS?
Do the existing values automatically flow to the correct locations or will I need to double check everything?
Since the maf has more cells and more clarity, what happens to the sections that previously had no value in the original OS? Are they left as blank spots for me to go in and interpolate?
I'm ready to upgrade, but I want to make sure I understand what's going to happen when I do.
