    Can you also post your .tun file

    ( E38/E67 is a lot deeper water than I can swim in, so it will take me a little longer to analyze )

    Here Joecar,
    We havent licensed the car just yet. but the other shop file was pulled from the car, named Stock File. We havent licensed and installed our speed density file (this is the tune file i created reading the E38 pdf).


    Pro Car Speed Density 0001.tun

    I just had a look at the tune files.....

    I seems you may have missed a step when changing the VVE zones. You didn't copy over the stock VVE and regen the coefficients. The VVE in "Pro Car Speed Density 0001.tun" is way off and I'm hoping you aren't driving that thing around!

    What's done to the car? Is it just a stock motor or are there mods done?

    I will look through the PDF again and look for the mistake.

    The original tune I pulled out was of 2 other shops previously. I do not have the factory tune and went off what I have.

    The Speed Density file has not been uploaded to the car yet. This is all done on our Dyno Dynamics but first I need the LC1 to communicate with the maps so I can dial in the load cells!

    -2010 camaro ss manual trans
    -Whipple Blower (dont know the psi)
    -Comp Cam and valvetrain components (sheet is at the shop with specs)
    -Liginfelter Fuel pump
    -ZR1 3 bar map
    -headers, exhaust, rotofab intake.

    Any help would be appreciated.

    OK, see how you go. Here's a really quick guess at the VVE for you to compare with, I wouldn't be surprised if it needs a fair amount of work though....

    PC-Swingy_0002.tun

    I'm not sure about what's happening with the LC1. You can play with the VVE just going by the STFT's, but you'd need to turn them back on. Actually, if you did a decently long road log, you could probably get the lower part of the VVE pretty close just using the trims.

    Thank you Swingtan, when i get home tonight i will look at both these maps.

    I noticed they have dfco turned off, they turned off long terms, and they have the maf set to enable 400rpms and disable 300rpms so it looks as if they are running maf all time!

    I come from a Japanese and European background in tuning. The owner of the shop is the GM tuner but has given me a challenge as i step more into domestics. I am trying to learn this and am 3 weeks in on reading this forum etc.

    Now you said i can do it with stft's is there a pid i can log in the maps to see where i am at with these trims? Also i dont think i found a target AF map for the ve tables, is there one somewhere?

    You can easily make a map...

    1. in tunetool:
    find the table that you want the AFR map to mimic,
    highlight the whole table, do copy-with-labels;

    2. in scantool:
    goto the properties of a new map,
    on each of the Row and Col tabs click Paste Labels,
    on the Data tab select the AFR you want (checkmark Names),
    then on each of Data, Row, Col tabs checkmark Show units;
    goto the Cells and Empty tabs and set them appropriately as desired;
    save as with a suitable filename.
