    LB72004,

    I see that you posted this spreadsheet back in February and then had a discussion on another thread with another tuner in August regarding these 3 tables, TBIQ, Base Torque, and TLIQ in which at the last post you acted like you had an 'ah-hah' moment. Did you get it all figured out? I still haven't had a chance to look into it further but I definitely have not had the 'ah-ha' moment yet.

    in terms of getting the excel sheet to work automatically, no.

    attached is the current sheet that i use for LB7s. to open it change the extension to "xlsx". it is the newer 2007+ excel file type.

    it shows the difference in MM3 between the the throttle base and the TLIQ. past in your tables into the "Math" tab and see what the difference is. the other tabs show the full information between the cells not shown in the tune, dont make any changes here. in the "Math" tab, adjust the base torque and torque limit injection quantity and if you want the throttle base till the green set of cells are as close to "0: as possible. when done past them back into the tune.

    i haven't proved that this is the correct way to tune the TLIQ or that it is safe but it has worked on two trucks so far. feel free to test it out, and please let us know the results

    Resurrecting an old thread. But thought It was kinda interesting. Looked at the math and found an error. In the TBIQ tab and Base Tq tab, you divided by 9 when you should have been dividing by 10, Just something to help you out. I knew you posted the LLY and LB7 ones somewhere else as I downloaded them a LONG time ago. Couldn't find that post again but did find it here.

    You made the same error in the LLY spread sheet as well.

    Good work tho.
