I want to tune a turbo truck. I don't get the 4th gen layout on the computer they made it more complicated then the older generation. So I'm trying to make a 2bar SD tune and get the remaining tables from 110kpa on up to 200+ whatever they are to tune for boost. I go to the virtual volumetric efficiency table and it's not there. As soon as I make a 2bar tune that option disappears. Can anyone explain to me how to get the file ready to read boost and for me to tune for boost?
