    High lighted are the things I think should be copied over to update my tune on the previous 1 bar tune( in red)

    So I just need confermation that the stuff below in red is what I need to change to update my 1 bar tune to the new 2bar clsd tune. Is this correct? thanks in advance.

    I did have to change shift point and did rfig rfin in the middle of on the ve tune(lower rpm map was good I just worked on higher rpm changes after rfig and rfin update.

    To run CLMAF, you set the MAF fail parameters and O2/trim parameters/tables back to stock.

    To tun CLSD you set the MAF fail parameters to fail the MAF (make sure that a MAF DTC trips).

    I know maf is maxed out and has been for a while that's why I got a 2 bar but thanks so clsd it is.

    Post your new tune and your old tune (containing the tables you want to copy to the new tune).

    I think some portion of your VE is not filled in with current data (where it dips down)...

    I hope you set the cells in B3647 and B3649 to values other than stoich (EQR 1.00) during tuning...

    if you didn't, then the COS would have trimmed using STFT when running on these cells.

    I think it's good to set B3618 to the same values as the 100kPa column of B3647 (B3618 is throttle based so it leads B3647 which is MAP based by a short time period).

    I also think it's good to have the last few columns of B3647 and B3649 extend all the way down (up in the table) to 400 rpms (consider this: what happens when you go WOT at 800 rpms, you're going to need fuel).

    With the COS you can run different HO B5913 and LOO B5913 spark tables (COS retains adaptive spark when MAF is failed).
