    2 bar VE table missing

    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?

    once you apply the custom OS the coefficients are gone.


    depending on what version of HPT your using, go back to the stock OS and you can take the VE from there to populate your current

    You lost me. The VE table is gone in the new OS. I don't have the option to open it. I'm using 3.0.

    Post the tune.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Here is the migration path for a 2008 Vette with a stock OS to a 2 Bar enhanced (on the left side) ,,,,,

    Ed M

    Stock 1 Bar on left and right side



    Left File being upgraded to 2 Bar enhanced OS; No VVE option available



    Left file now contains conventional VE table in place of the VVE; bear in mind it is populated with zeros just after the upgrade and must be re-populated

    Use the built in virtual VE editor which lets you set it up for whatever range of boost you want

    Or do the 2 bar OS upgrade (that is free by the way) and then you get "regular" VE tables again.
    Post a log and tune if you want help
