    Default B1703 not Showing in the E-38 COS

    Can someone please show me how to open B1703 in the E-38 COS so that I can directly adjust that parameter?

    E38 Custom OS, is this the Ethanol enable switch?

    B1703 is in the Idle parameters of the E-38 OS 22614676 and is titled Airflow Area Conversion Max with DTC. Hymey told me to raise this valve to max when tuning the idle for large cam and boosted applications.

    Yes he is correct as some of the factory cals have that set very low.
    I can see the .calz files for the COS has not been regenerated with updates since 2014, but the change log shows that parameter was added in 2015 so it won't be in any of the COS's.
    Are you running E85? If you aren't then there is probably no need to use the COS.

    Thanks you for the reply. I am running NOS along with the Blower but not all of the time, so I would like to keep the COS files if at all possible. When I do a backwards comparasion between the stock and COS (Stock to COS files), I can see B1703 in the stock files and it is visible in the COS but I cannot change it in the COS so I know it is there. I have two COS files that TAZ added a cruise control mod to back in 2015 that I need to use. Is there procedure that I can do to regenerate the COS files?

    No that is something we need to do but I'm not going to do for this (it's a bit of a convoluted process to generate and validate the .calz file once they fall behind so far).
    What you could do is just to fix that B1703 calibration is this procedure:

    1 - In Windows File Explorer go to - C:\Program Files (x86)\EFILive\V7.5\Calibrations\E38
    2 - Copy 12614676.calz in to - C:\Program Files (x86)\EFILive\V7.5\Calibrations\E38\Custom
    3 - Rename the existing 22614676.calz to something else (you will change it back again later)
    4 - Rename the 12614676.calz you just copied to 22614676.calz
    5 - Reopen your tune in V7 and you should see that parameter

    When done just delete that renamed .calz and restore the original .calz, don't leave them like you just changed them.

    Cheers,
    Ross

    You guys always have the best answers and Thank You very much. If I were close I would buy you dinner or a cold one but I dont think that is possible given the distance. Just to make sure I throughly understand the instructions (by the way it is working, so I might have done it correctly) I have completed steps 1-5. I can now see B1703 in the COS. The last part sort of confused me. I copied 12414676 in step 2 into custom then changed it to 22414676 after changing the original to a different Number. I then I deleted the 22614676 that I changed to a different number (22222222), but since I copied the 12414676 out of step 1. from above, the original is still in is Calibrations/E38. Am I supposed to restore the original back into Calibrations/E38 if It is still there? I hope this is not a dumb question

    If the original 12414676 remained in the main E38 folder then there is nothing more to do, to be on the safe side just reinstall V7 and it will put everything right again.
    It was a quick and dirty hack but I'm glad it did the job, I would never normally recommend that as the COS .calz files usually aren't 100% compatible but in this case for what you wanted to do it was ok.

    Thank you Ross or as you would say, "Cheers" :-)
