    Your E38 pid selection looks good to me.


    Copy the tables/parameters from the first file to the second file:
    - open the second tune as the current tune,
    - open the first tune as the alternate tune,
    - press the differences button (red left/right arrow), this brings up the Compare tab,
    - do ctrl-A to select all differences,
    - press the Update button (copies the tables that differ from alternate to current), wait for it to finish,
    - press the Save As button and select a new filename.

    Flash this in, check what IAT does, and report back.

    If I pull that off without screwing it up or saying "oh shit" I should get a free Aussie Beer!

    Ok, I'll give it a whirl and see what happens.

    Snort, I think I did it without messing up. It's almost 8PM here. I'll upload the resulting file on Wednesday and see what IATs I get. Thanks for helping the old folk!

    Than

    Only if the "merge" doesn't make my ECM a paperweight.

    I'll let you know what happens.

    Ok, we did the merge. I loaded it into the ECM and we have different data! My current temperature is 58 (early in the morning) and my IAT is -8 F. I will NEVER pull timing while driving at the North pole!

    I will make another post with what I did next.

    After the -8F I loaded this tune. I then ran a scan while I drove. Notice the sudden increase in IAT? There is something wrong with the EFI Alchemy (local tuner) tune that is blowing the IAT reading into never-never land.

    That makes no sense... in the log in post #19 IAT ranges from 75°F to 77°F.

    Have you contacted Doc at EFI Alchemy...?
