What happens to my existing tune when I upgrade to the 2.5 bar custom OS?

Agree 100%. The upgraded OS works really well from what I could tell playing with it for a few hours. I'll just have to go back and revisit the map settings.

So how'd this go?? I have a test file saved and have been comparing the 2 bar to the regular OS. Two things that I see right away; 1) the MAF Hi table is different and has 300 rpm steps verse 200 rpm steps. I suppose you could manually populate as many cells as possible from the original tune file, then interpolate between cells... 2) There are new VE tables, but the original coefficient tables are still there as well. I have no idea what to do about that... I thought the VE tables replaced them.

It went fine. Been running on the new OS for a few weeks now with no issues. I just input the knowns and interpolated the rest. I copied/pasted the map offsets from my original file and everything went off without a hitch.
